A Sign of Quality

The Manufacturer and Certifier

PAM access covers and gratings

consistently manufacture products of

the highest quality in adherence

with the BS EN 1SO 9000 series of

quality systems, approved by the

BSI, under the registered firm

approval scheme. This involves

periodically subjecting the company, its

processes, and its suppliers to the most

rigorous and objective assessments, providing

reassurance that the consistently high

standards of quality are maintained.

Further assurance of product quality is

gained from the fact that the majority of the

PAM product range is also certified with the

prestigious British Standard Kitemark.*

This internationally respected symbol of

product quality accredits the following

standards relevant to municipal castings

manufactured in the UK:

BS EN124 (1994)

European standard for gully tops and

manhole tops for vehicular and pedestrian

users

BS 5834: Part 2 (1983)

Specification for small surface boxes

BS 5834: Part 3 (1985)

Specification for Large surface boxes

BS 750 (1984)

Specification for underground fire hydrants

and surface boxes and covers

Today, quality is of paramount importance

in the construction of the road network, not

just to manufacturers, but to suppliers, installers

and road users. With the ever increasing

traffic volumes on our roads today, the strain

placed on access covers and gully gratings is

at its highest levels.

In this climate, specifiers have become

increasingly conscious of their obligation to

ensure road user safety by demanding

products that are manufactured and tested to

the highest standards. Customers can be sure

that the PAM product range bearing the BSI

kitemark are of the highest quality and have

been independently certified as complying

with BS EN124.

The Certifiers Accreditor

When specifying products that are by their

nature installed in very onerous locations,

much due care and attention must be

placed on selecting a manufacturer that is

certified by an institution such as the BSI.

A specification can request that products

are ‘kitemarked’ or ‘similar approved’. The

difficulty for specifiers is defining what is

‘similar’.

References to EN 45012, EN 45011 and

EN 45001 will help ensure that the

competence level of the certifying

organisation has itself been

assessed. In the UK, specifiers can

request that the certification

organisation has been accredited

by UKAS (United Kingdom

Accreditation Service)

With this in mind we recommend that

specifiers request the following:1) The Manufacturers

ISO 9001 CertificateBS EN 124 Certificate & Product Schedule

2) The Certification BodiesEN 45001 CertificateThis is the schedule for site andlaboratory testing, which demonstratesthey are approved for BS EN 124EN 45011 CertificateCertifies the issue of productconformity certificates within thescope of BS EN 124EN 45012 ScopeThe scope, which demonstrates thatthey can assess a manufacturer toISO 9000

PAM access covers and gratings

manufacture a range of high performance

ductile iron access covers and frames. We

recognise the need to provide a material that

is capable of combating the wear

characteristics inherent with the increasing

amount of vehicular traffic on our roads

today.

What is Ductile Iron

Spheroidal graphite or ductile iron is a

unique form of iron which prior to the metal

casting process receives a treatment with

magnesium to produce an exceptionally

strong, impact resistant durable metal.

The difference between Ductile

and Grey Iron

The addition of magnesium at the molten

stage transforms the flakes of graphite which

are common with the grey iron casting

process and transforms them into spheroidal

or nodular form. The spheroidal structure

provides a higher tensile strength as well as a

higher ‘strength to weight’ ratio when

compared with the properties inherent with

grey iron manufacture.

The benefits of Ductile Iron

Ductile irons high strength to weight ratio

allows for the production of light weight

castings that offer what can amount to a 50%

weight saving over traditional grey iron

equivalents.

The high strength inherent with ductile iron

not only minimises the risk of failure when

installed but reduces the likelihood of

breakages in transit and off loading.

In a market place that is increasingly

being encouraged to specify products that

offer less of a manual handling risk, the dead

weight of the castings during both installation

and actual operation in service is recognised

as a key feature and obvious attribute.

Ductile Iron Spring Bar Technology

Continual development on advancing the

elasticity inherent in ductile iron has provided

PAM with a unique method of locking a

number of its units. The ‘Spring bar’

technology uses the ductile iron’s elasticity in

the area where the components interact and

allows for the locking of the grating or cover

within the frame without the use of a

mechanical locking device. There is an

obvious benefit to simplifying the current

methods used to retain a cover or grate within

the frame.

The spring bar tecnology will allow for

stability under load and silence in operation.

Gully Gratings and the Ductile Advantage

Ductile iron’s inherent properties of high

tensile strength and resistance to impact

allows the waterway area of gully grates to be

evenly distributed over the surface of the

gratings without losing structural strength. This

provides improved drainage efficiency per

clear opening size, particularly in the 90mm

area closest to the kerb.

requirements of the European Standard BS

EN124. This applies to all situations, road and

off-road and all materials. Products designed

to BS EN124 are grouped and classified

depending on their place of installation.

It is the responsibility of the engineer to

ensure that the correct product is specified:

‘‘The appropriate class of manhole top or

The BS EN124 standard provides a general

guide to product stability and sets out test

load parameters for the various classes of

products in terms of static load tests.

However, it provides little specific

information on dynamic loads imposed by the

wide variety of traffic conditions found on

modern road systems.

Product selection in most cases is a

simple matter, but long association with

specifiers has convinced us that there are

certain conditions which dictate a little extra

care in making a selection. The diagram

illustrates vulnerable spots where products

may be subjected to extreme loading.

With BS EN124 offering little or no

guidance on selection of products under

dynamic loads, PAM has developed a

portfolio of products incorporating the

Interaction range of covers and gratings

which, when complemented with the

selection guidance software, enables the

specification engineer to make the right

choice with confidence.

2. Roundabouts

Turning vehicles encourage movement

between cover/grate and frame and can

increase wear. Gully grates are particularly

vulnerable at clipping points.

1. Dual Carriageways

Speed of traffic increases the impact

loading on castings and deceleration areas

at roundabouts can be

particularly aggressive.

3. Hard shoulders

Changes in traffic flow necessary to

accommodate maintenance work or

emergencies, can result in units being

required to accept loadings and conditions

for which they may not have been intended.

Note: In each of the circumstances outlined

above, a product of a high specification

should be considered. For further advice,

7. Narrow lanes

Width restrictions can lead to road

castings being heavily trafficked, particularly

on bend clipping points. Gully grates are

particularly vulnerable.

6. Traffic calming

The installation of traffic islands and

narrowing of roads to slow traffic will increase

the vulnerability of gully grates to clipping.

5. Bus routes

The pulling into the kerb or lay-by and

braking of buses result in gratings being

legislative requirements and allows for a more accurate product specification

within any given installation or environment.

I r o n I n t e r a c t i o n w i t h t h e H i g h wa y

The Nottingham University research gave us an understanding

of the transfer of the dynamic loads from traffic onto the manhole

cover and subsequently from the manhole frame to the chamber

structure. It was found that in conventional designs the load is

concentrated at the corners of the casting creating excess strain

on specific areas of the bedding material. The new LTS feature

(Load Transfer System) designed specifically to reduce this strain in the mortar thereby reducing the

risk of cracking which can cause premature failure.

LTS Load Transfer System

The system comprises the following four features:

1. Corner Webs

The shape of the flange has been optimised so that there is an increased area where the

load is concentrated. This minimises the strain in the bedding and will give a reduction of

measurable strain between 30% to 50%. The design increases the ‘Pressure Bearing Area’

where the load is concentrated and provides excellent seating for good installation. The

reduction of flange width between the corners has the effect of reducing torsional stiffness

whilst retaining the necessary bending stiffness thus avoiding vertical deformation of the

casting and the resultant strain in the mortar.

2. Rib Positioning

The positioning of the ribs plays a critical role in reducing the risk of cracking the bedding

material due to frame deflection. The position opposite the cover seating areas reduces the

risk of deformation and ensures that impact to the surrounding materials is limited.

3. Bonding Ribs

The increased contact area provided by the rib design significantly improves the bonding

of the casting to the bedding material creating a greater resistance to lateral shift. The

improved bonding helps to avoid early separation and cracking of the bedding material

which can cause premature failure.

4. Flange Stiffness

The thickness of the flange at the corners prevents bending caused by dynamic loading from

the wheel. The prevention of bending in this area reduces the disturbance of the bedding

material.

Historically, traditional access covers were

designed and manufactured with just one

objective in mind - road performance and

longevity. This unfortunately has had an adverse

effect on the kilogram unit weight and the design

methodology facilitating the covers’ removal from the frame, which

ultimately, allows for safe access to the chamber.

However, in today’s legislative environment, where the employer has

to ensure the safety and welfare of the employee at work, PAM has

taken access cover safety design to a higher level.

The Health & Safety Environment● Manual Handling

More than a quarter of the accidents reported each year to the

enforcing authorities, are associated with manual handling. The vast

majority of of these result from an “Over 3 days” injury. The most

common types of injury are sprains and strains - often to the back.

● Back injury

The most common cause of back injury is:

i) The operative’s poor posture when lifting

ii) The excessive repetition of the lift

Many of the manual handling injuries are cumulative rather than

being truly attributable to any single handling incident.

● Access Cover Removal

Effective upkeep of today’s sewerage and telecommunications networks demands a regular

checking and maintenance programme. This obviously has an effect on the number of access

covers the operative has to remove in any working day.

It is the regularity associated with traditional access cover removal that can expose the operative

to the possibility of a repetitive strain injury (RSI), which can result in physical impairment or even

permanent disability over a period of time.

PAM has taken these factors into account and a lengthy research programme has resulted in the

development of an “ergonomically positive” range of access covers that “fits the product to the

person”.

I r o n I n t e r a c t i o n - P o l y e s t e r R e s i n B e d d i n g M o r t a r

Failure of the cementitious bedding

mortar was found to be a principle cause of

failure of road ironwork installations. Cracking

of bedding material caused the ironwork to

become loose. Cracking occurred due to a

number of factors:● Shrinkage of the mortar during installation.● Mortar having insufficient strength. Both

compressive and tensile strain is built up

during loading.● Installation opened to traffic too early.● Differential stiffness between the manhole

chamber and the surrounding road.● Movement of the frame and flange of the

casting under dynamic loading.● Failure of the bond/adhesion between the

casting and mortar giving rise to separation.

An understanding of the behaviour of the

ironwork under loading and the subsequent

load transfer was developed along with the

quantification of the strength (compressive

and tensile) requirements of a bedding

material.

PAM’s engineers in collaboration with SBD

Limited (manufacturers of specialist

construction mortars) have now developed

the new LTS feature designed to increase the

long term performance of an ironwork

installation. This includes Iron Interaction

Polyester Resin Manhole Bedding Mortar which

has been purpose designed to provide:● Long-term strength● Resistance to shrinkage● Long term durability● Optimum workable properties● Early site opening● Consistency of performance

Used in combination with products that

incorporate the LTS frame design feature, the

new Iron Interaction Polyester Resin Manhole

Bedding mortar will reduce the incidence of

premature failure and improve the long term

performance of an ironwork installation.

Strength properties

The Nottingham research identified and

quantified the required strength to withstand

the dynamic loading of a vehicle wheel. The

Iron Interaction bedding mortar exceeds this

performance level in both compression and

tensile load.

Optimum workable properties

Ease of installation is an important

element in ensuring good site practice. The

bedding mortar has been designed to allow

enough working time to set the manhole and

a ‘slump’ to give easy manipulation during

bedding preparation.

Durability

Resistance is excellent to environmental

conditions found in the highway. The mortar is

resistant to the action of frost. It will not react

chemically with de-icing salts. It has a low

permeability which prevents damage to

ironwork by chloride ingress.

Material Specification

The table below indicates the general

Using the following set of criteria to

determine the type of use that a casting may

undergo during its life will help the specifier

choose the correct casting:

Speed: Restricted or de-restricted areas?

Volume: Density of traffic. Continuous or

sporadic?

Type: Lorries, cars, buses etc?

Road: Inter-city road, urban, estate, rural?

Placement Wheel tracks, verge etc?

Location Bend, junction roundabout etc?

Zone: Accelerating, decelerating or constant

speed zone?

Future: Likely development of area?

All of these criteria will affect the

performance of the installation as different

types of loading occur on the casting in the

dynamic environment that they are utilised.

The Traffic Intensity system designates

castings as either High Intensity (H), Normal

Intensity (N) or Low Intensity (L) and choice

can be made dependent on the severity of

the determining criteria.● NEW - Introducing the ergonomically

positive feature. The new specification

software will include criteria whereby you

can create a more accurate selection

given not just the area of installation but

the application and the operational

frequency the product will be subject to

throughout its life.

The benefits of using this type of selection

criteria:● Aids the selection of the optimum casting

for a given installation and application.● Removes the risk of minimum

performance castings being installed.● Removes the need for local knowledge.● Increases confidence in the selection

process.

The Nottingham University research

highlighted the need for a more modern

approach to the specification of products.

Many engineers highlighted the increasing

difficulty in specifying castings with the

‘optimum’ performance for a given

application. EN124 only gives minimum

performance requirements which are not

always suitable for the UK market.

It is recognised that there is a number of

different D400 castings available on the UK

market and engineers need a sensible way of

ensuring that correct one is chosen for the

application. Simply stating ‘D400’ as the

criteria will inevitably lead to low specification

castings being used.

Currently in the UK the major

manufacturers differentiate castings by the

use of ‘Road Type’ e.g. Trunk roads, city roads,

estate roads etc. This is a very limiting factor

and will not ensure that the optimum casting

is used. This process also relies on local

knowledge which is increasingly unavailable

as more work is undertaken by engineering

consultancies who may not be located in the

vicinity of the scheme.

Traffic Intensity specification

PAM has introduced the “Traffic Intensity”

system to help the engineer to specify the

optimum choice of casting for any given road

application.

In addition to the standard group classifications detailed in BS EN124, it is recommended that the

following criteria should be taken into account when selecting the most suitable product:● The traffic stresses and specific load dynamics on the ironwork● The number of inspections required

Traffic Stresses and Load DynamicsBS EN124 is of minimal assistance in guiding a specifier to the correct specification given the

load dynamics of the actual installation, it is recommended that the following method is applied

when selecting the appropriate access cover.

For example, the dynamic loads placed on a D400 cover would be different on a busy ‘A’ road

when compared to a built-up area where speed is restricted. In addition, braking areas such as the

approaches to traffic lights, junctions or turning circles affect the actual loading of the ironwork.

PAM has designed a range of covers that accommodate the various forms of dynamic loading

occurring on our roads today. The D400 Class is segmented as follows:

Operational FrequencyEfficient management of the sewerage and telecommunications networks requires more

frequent inspections and checks. With this in mind, PAM has designed an ergonomically positive

range of access covers that will allow an operative to use the unit both frequently and safely.

Type of CollectionRun-off water can be collected by a variety of drainage gratings as follows:

Location of Gully PotThe type of drainage that is used is generally determined by the location of the gully pot and the

design of the below ground network. There are usually two options which are as follow:

i) Directly under the carriageway - Where applicable, a D400, C250 or B125 hinged/double

triangular gully grating.

ii) In the kerb-line - Where applicable, a D400 or C250 kerb gully unit or a hinged/double

triangular gully grating set into the kerb-line.

Inter-Ax also features a fibre-optic ‘point of

drilling’ hole in the cover, avoiding the

underside cover webs to provide access into

the sewer for fibre-optic cameras.

The LTS design eliminates the traditional

‘grouting hole’ which was found to increase

the strain in the mortar if positioned incorrectly.

Holes are provided in non critical areas to aid

lifting or provide bolt holes to secure the

frame to the manhole chamber.

Specification and selection of the Inter-Ax

range is made simple by using the Traffic

Intensity Specification and Selection software.

University research

The Inter-Ax product range was developed following an extensive three year research

programme. The research was conducted by the University of Nottingham in conjunction with The

Department Of Transport, Scott Wilson Pavement LImited and PAM Access Covers and Gratings.

Objectives

The objectives were “to fully understand the mechanism of failure of ironwork installations”

and to determine what actions could be taken to remedy them.

The research consisted of three main elements:● Real life installations● Laboratory trials using purpose-built test-rig● Finite element analysis

Conclusions

The research concluded that the road ironwork installations failed prematurely because of the

following:● Traditional cementitious bedding mortar being unsuitable for ironwork installations● Movement of manhole cover frame under dynamic loading● Wrong products being specified and selected

Product feaures

The Inter-Ax range of traditional

lift covers has been developed

with the research conclusions in

mind and incorporates the new

LTS feature.

The Inter-Ax range has been specifically

engineered to cope with all the varying traffic

loadings encountered on today’s busy

highways.

The D400 products are marked with one

of the following “traffic intensity markers” to

simplify specification and selection of the

most appropriate casting:

‘H’ for High traffic intensity

locations

‘N’ for Normal traffic intensity

locations

‘L’ for Low traffic

intensity locations

All the Inter-Ax range has been developed

for use with the PAM Iron Interaction Bedding

Mortar.

Continued research into the area of safe

cover removal stimulated by ever increasing

legislation resulted in the development of

Tri-Glide, a range of ductile iron one man-

operable D400 covers and frames with a

unique slide-out action for safe, easy opening.

This range of ‘user-friendly’ covers was

developed mainly to help the client and

associated contractors meet these tougher

health and safety requirements by the

incorporation of a number of forward-thinking

design features.

Features

The patented slide principle and inverted

‘V’ 3 point suspension designed with increased

seating area for maximum stability, all

contribute to make Tri-Glide one of the most

ergonomically positive covers available.● Dual directional ramps located within the

frame act as runners for the cover and

stiffen the frame to prevent movement

under dynamic load.● Sliding action facilitates a quick inspection

of underground services without the need to

remove the covers completely.● Integrated keyhole and prising slot enables

easy removal of debris allowing the key to

be fully inserted prior to commencing the

lifting operation.● Keyholes located adjacent to the cover

edge, eliminate the need to stretch in order

to engage the lifting key.

Research and Analysis

Research conducted in association with

North West Water by the University of Salford’s

movement analysis laboratory demonstrated

that:● One operative required to remove a

Tri-Glide cover is at far less risk of back injury

than EITHER OF THE TWO people required to

remove a traditional access cover. In fact,

the stresses which can lead to back injuries

such as slipped discs are reduced by a third.● The research also revealed that the duration

of the lift with Tri-Glide is reduced as the cover

only needs to be lifted to the frame edge

from where it can be moved clear of the

frame by the patented sliding action. In

comparison, traditional covers need to be

lifted clear of the frame before the lift is

complete.● Opening Tri-Glide allows for more

symmetrical body positioning. The operative

is thereby protected from the rotational forces

that occur during traditional cover-lifting

procedures causing further spinal

compression. The research demonstrated

that the compressive and torsional forces on

the most vulnerable area of the lower back

(L5-S1: the joint of the fifth lumber vertebra

and first sacral vertebra) are significantly less

with Tri-Glide than the conventional 2 person

cover. The mean axial compression was also

found to be 35% lower with Tri-Glide in

comparison with the traditional cover.

Compressive forces are potentially the most

injurious to the spinal column, as they squeeze

the soft centre of the disc cushioning the

vertebra, encouraging posterior disc bulge

(more commonly known as “Slipped Disc”).

The Salford University report is availableupon request from Saint-Gobain Pipelines.

NOTE: The study was undertaken using 9 male

subjects, ranging in age, weight and height.

Of these 5 were network controllers from

North-West Water regularly involved in handling

manhole covers.

Ergonomic Lifting

In order to maximise the manual handling

benefit of the patented Tri-Glide cover system,

PAM has developed a revolutionary lifting key.

The new key design will offer the operative

a number of benefits including:● Greater compliance with manual handling

regulations (1992) through a reduction in

compressive forces which can lead to

spinal injury.● Improved safety through the provision of

a more stable foot position during the initial

stages of the lifting manoeuvre.

measurable strain between 30% to 50% in the

bedding.

Bonding RibsRib design significantly improves bonding to

the bedding material creating a greater

resistance to lateral shift. This helps avoid early

separation and cracking of the bedding

material which can cause premature failure.

Rib Positioning

Positioning of the ribs plays a critical role in

reducing the risk of cracking the bedding

material. The position opposite the cover

seating areas reduces the risk of frame

deflection and ensures that impact to the

surrounding materials is limited.

Flange Stiffness

The thickness of the flange at the corners

prevents bending caused by dynamic

loading. Prevention of bending in this area

reduces disturbance of the bedding material.

lift the cover slightly to clear the retaining

shoulder, then close. (The covers cannot

close accidentally as they MUST be lifted over

the shoulder at the 90° position.

(See column to right : “Closing Sequence”.)

Simple removal

To allow safe access to the chamber,

each cover can be easily lifted out when

moved to the 90° position.

(See column to left : “Removal”.)

Other Opt-Emax FeaturesLocking option

Opt-Emax can be locked if required and

locks can be fitted retrospectively.

Three-point seating

Three-point suspension seating design

gives long-term performance and stability in

today’s traffic conditions.

Ergonomically positive (E+)Effective upkeep of today’s networks

demands a regular checking and

maintenance programme. This has an effect

on the number of access covers the

operative has to remove in any working day.

It is the regularity associated with

traditional access cover removal that can

expose the operative to the possibility of a

repetitive strain injury (RSI), which can result in

physical impairment or even permanent

disability over a period of time.

Reduced risk of injury

The hinged mechanism greatly reduces

the risk of back injury thanks to the reduced

effort required to open the covers.

Closing

To close, simply move to the 90° position,

■ Move cover to 90° andlift over retainingshoulder

■ Lower cover to close(Units close in reversesequence to opening)

debris during long dry periods and a number

of heavy duty manhole covers are capable of

taking a seal plate to prevent the escape of

offensive gases and act as a defensive barrier

against corrosion

The PAM range is supported by an

extensive network of agents/stockists and

representatives focusing on local customer

service. Customers vary from large

telecommunications companies to water and

sewerage utilities all using the latest design

technology and keen to benefit from PAM’s

innovativity and our commitment to provide

high quality and service.

The PAM range is available from stocks

strategically located throughout the Middle

East.

The Watershed gully grate has been

developed to meet the needs of engineers

and the rigors of todays traffic loadings.

Watershed offers ease of maintenance

with its prising slot for quick opening and

hinged action.

Watershed combines the benefits of both

double triangular and hinged grates in one

unit. Thanks to its wedge seating, Watershed

provides non-rock performance and the

captive hinge allows fast and easy access.

Manufactured from ductile iron the

Watershed utilises the wedge seat principle.

The Watershed wedge seating operates in

two directions and has seats to ensure the

security and location of the grate within the

frame.

Product FeaturesThe results of the tests are as follows:

1) Multi-directional Flood Deflector

It was established that the directional

deflectors facilitated the breaking up of the

water “sheet” as it hit the grating, which in turn

improved on the amount of water that is

captured. The deflector design also allowed

for the more efficient dispersal of leaves that

can build up over the waterway area slots of

a traditional gully grate.

3) Safety Features

The Flat Squadra units can be rotated 90¯

within the frame.

This feature means that the grating can

be placed perpendicular to the flow of traffic

irrespective of the way the frame has been

installed.

2) Spring Bar Technology

The grating is seated in the frame using

two spring-lock mechanisms in ductile iron.

This technology has also been integrated with

Autolinea and Selecta product ranges

The Squadra was developed as a result of an extensive testing programme in an attempt to

establish the true characteristics of the water flowing over and into the gully grating.

S e a l P l a t e s & S a f e t y G r i d sA comprehensive range of product

accessories is available to enhance, protect

and increase safety.

The accessories include:● Seal Plates

- mild steel galvanised

- GRP● Safety Grids● Personalised badging● Lifting Keys

Bolt Down Mild Steel Galvanised (MSG)

Seal Plates

Under surge conditions, pressure concen-

tration in access shafts can lead to covers

being forced out of manholes. In situations

where this may occur, PAM offers a bolt down

MSG seal plate for added security.

MSG seal plates are fixed inside the man-

hole frame and secured using eight set

screws. MSG seal plates are specially

designed to overcome problems of back

pressure experienced in sewer shafts up to 0.5

bar (equivalent to pressure of five metres

head of water).

Installation (MSG)

When installing the manhole frame it is

important that the bedding mortar does not

interfere with the bolt holes used to retain the

seal plate. Before installing the seal plate,

ensure the sealing gasket and surface of the

frame in contact with the gasket are lubricat-

ed using a soft soap. (The lubricant used for

Tyton pipe gaskets is also suitable). Washers

should be placed under each set screw

head. Set screws, wrapped with thread seal-

ing tape, should then be tightened evenly to

avoid possible distortion of the seal plate.

Note: Bolt down MSG seal plates cannot be

retrospectively fitted.

Push-fit Glass Re-inforced Plastic (GRP)

Seal Plates

GRP seal plates act as a protective barrier

against the egress of odours and the corrosive

properties of sewer gases, notably in countries

where the ambient temperature is high.

GRP push-fit seal plates are not capable

of performing under conditions of back pres-

sure.

Installation (GRP)

Push-fit GRP seal plates can be easily

installed with the frame in-situ, and are readily

removeable allowing fast access to shafts.

Note: Push-fit GRP seal plates may be retro-

spectively fitted in appropriate frames.

Safety Grids

Specially designed MSG safety grids rest

on the frames internal lip and are designed to

prevent the entry of objects into the sewer

shaft when work is being carried out.

Safety grids are of drop-in design for ease

of location in manhole frames and can be fit-

ted retrospectively. Bar type and mesh type

are available in appropriate frames.

The standard badges for manhole and

access covers are “FW” (Foul Water) or “SW”

(Surface Water). For details of standard

badging for surface boxes, see individual

product pages and tables below.

Special Badging

Special badging of castings to individual

customer requirements is also available,

dependent on specific order quantities and

suitability of particular designs. Please consult

PAM’s Sales Department.

Ductile Iron Product Coating

PAM access covers and gratings are

supplied coated with cold applied black

bitumen as standard. Castings may be

supplied uncoated on request (Fine Cast).

Bitumen acts to protect casting surfaces

whilst in transit and on the stockground. In

situations where castings are subjected to

regular vehicular traffic the coating on the top

surface of the casting will become worn. This

has no adverse effect on the casting’s

performance.

Safety gridA frabricated galvanised mild steel grid, which normally drop fits onto the frame below the cover toprevent covers and other objects being dropped into the shaft.

Seal plate (bolt down)Galvanised mild steel plate, fitted with a gasket, which is bolted to the frame to prevent egress ofodours and which may limit the ingress of water. Capable of withstanding a back pressure of 0.5bar.Cannot be fitted retrospectively.

Seal plate (push-fit)Glass re-inforced plastic (GRP) plate, fitted with gasket, which is a push fit into the frame and preventsegress of odours and which may limit the ingress of water and, especially in countries with high ambi-ent temperature, acts as a barrier against the corrosive properties of the sewer gases. Not capableof sealing under back pressure. May be fitted retrospectively.

SealedCovers and frames which are sealed in some way to at least prevent the egress of odours from thesewer. There are different methods of sealing and these give varying standards of performance.See DOUBLE SEAL, SINGLE SEAL, SEAL PLATES AND PRESSURE TIGHT.

SeatingBearing/contact area between cover and frame. Also type or contact:Three point seating: Non-rock seating; Machined seating; Gasket (rubber) seating

Single PieceCover/grating comprises one piece.

Single sealTraditionally single vertical tongue in groove relationship between cover with single rim and frame withsingle groove. Allows single grease seal against egress of odour llimits ingress of rainwater. Also seeSEAL PLATE.

Slide outCover removed by lifting one end then sliding out rather than direct vertical lift. Reduces the effortneeded for removal.

Ventilated coverOpenings within cover allow free circulation of air within the shaft and prevent pressure build-up.Minimum vented area is specified in BS EN124.

R e i n s t a t e m e n t a t e x i s t i n g s i t e

Before beginning any reinstatement work it

is recommended that a site assessment is

carried out. This can often save considerable

time on site through improved planning. The

assessment should identify

i. Type of reinstatement required

ii. Whether or not a new cover or grating is

required. If a new unit is required then the size

and type of unit should be identified. This

should include the frame depth of the existing

unit as it is quicker and more cost effective to

replace the old unit with one of equivalent

frame depth. This will save having to build up

the chamber in order to bring the cover to

road height.

iii. The extent of work required. This should

include any repairs required to the brick

chamber, the urgency of the work required,

whether a short term emergency repair is

required and an estimate of how long the

work will take.

There are currently many different

bedding materials available in the market

place. The factors governing the choice of

material are:● Long term strength properties● Resistance to shrinkage● Optimum working properties● Early site opening● Consistency of performance

To meet all of the necessary requirements

PAM recommends the use of Polyester Resin

Manhole Bedding Mortar. This

recommendation arises from a 3 year

research programme, in conjunction with

Nottingham University, Scott Wilson Pavement

Engineering Ltd and the Department of

Transport, to investigate the premature failure

of road ironwork installations.

The research revealed that the main

cause of premature failure was the cracking

of the bedding material, causing the ironwork

to become loose. In order to remedy this

problem, a greater understanding of the load

transfer mechanism, and the interaction

between the ironwork, mortar and surrounding

ground was first developed.

From this the revised performance

specifications were defined.

C) Seat casting

Position casting frame

over the manhole

chamber and lamp

down tamp down to

ensure that the mortar

keys to the casting.

D) Level casting

Ensure that the casting is

level with the road

surface by placing a

straight edge across the

corners of the casting

onto the road. Frame

can be made level by tamping the frame

into the bedding material.

E) Check gaps under

flange

Ensure that there are no

visible gaps under the

flange and smooth

bedding material with

trowel both inside and

outside of chamber.

F) Envelope flange

Use, the remaining mortar

to envelope the flange

paying particular

attention to the corner

areas. Smooth out the

mortar with a trowel to

ensure good bonding with the casting and to

avoid any initial cracks in the bedding

material.

G) Backfill

Check that the bedding material has

hardened and backfill with asphalt. Ensure

that the asphalt is properly compacted.

Installation in new roads

When installing covers in new roads, where the

road surface has not yet been applied,

embedment is made easier. Simply follow

Stage 2: Material selection and Stage 4:

Installation.

C ov e r, g r a t i n g a n d s u r f a c e b ox i n s t a l l a t i o n

A) Excavate ironwork

Remove old ironwork

ensuring that all cracked

asphalt is removed from

surrounding area.

B) Clear and repair

brickwork

Clear brickwork of all

debris and old bedding

material. Check the

manhole chamber for

loose brickwork and

crumbling mortar. Replace any loose bricks

and repoint as necessary. Check that the

manhole frame will seat evenly.

When installing access covers with a 100mm

deep frame, rebuild the brickwork chamber to

a minimum level of 115mm below the

carriageway surface using at least Class B

engineering bricks (165mm below surface

using 150mm deep frame). Any bricks used

should have a compressive strength of not less

than 20N/mm

A) Mix material

Material is pre-blended in

controlled quantities. Pour

the liquid polyester resin

into a suitable container

followed by the powder

hardener component.

Using a mechanical mixer ensure that the

material is thoroughly mixed (wetted).

B) Bedding layer

Place layer of bedding

mortar on brickwork

approximately 25mm to

40mm in depth. Ensure

that enough coverage is

available to make

contact with the entire flange of the casting.
