HS-range HS-range HS
ProductThe HS®-range provides the user with a complete system having first-rate constructional properties in the nominal siz-es DN/OD 110 to DN/OD 630. Apart from pipes and drain-age fittings from the standard program, special elements, like the HS®-VARIO socket, the HS®-Demarcation Chamber, a HS®-Access Pipe and various bends as well as chambers for the most diverse application areas, provide for the perform-ance and variety of applications of the modern underground drainage pipe system. Pipes and drainage fittings have a firmly inserted, oil resistant FE®-Sealing.
The revolutionary idea to produce a pipe system in multiple colours has proven to be very good in practice. Because of the blue (rainwater) and brown (sewage water) colouring of the HS®-Pipe range, the association of the coloured pipes and drainage fittings is possible without any problems even

many years after laying, both from inside and outside. The whole pipe system meets the increased requirements of Ger-man ATV-DVWK-A 142 – impermeable up to 2.4 bar – and may therefore also be utilised in water protection areas of the II/III zone.
There are benefits for contracting public entities as well as for private clients both in new building and development activities or in the rehabilitation of existing mains systems. All components of the HS®-Pipe System have a long lifetime of 50 to 80 (100) years according to Bund-Länder-Arbeits-gemeinschaft-Wasser/LAWA. Moreover, the product is ap-proved by the Deutsche Institut für Bautechnik (DIBt, Ger-man Institute of Construction Technology).

FE®-SealingAll components of the HS®-Pipe System feature an oil re-sistant, firmly inserted FE®-Sealing. It is a two-component sealing in red and black colour, in which the sealing material is sprayed onto the support ring made from PP. During pro-duction, the sealing is mechanically or manually placed into a pre-formed bead or sealing chamber. Due to production characteristics pressing out or even forgetting the seal dur-ing installation is not possible anymore.

Pipes Pipes Pipes Pipes HS®-Pipe System – the components
HS®-Pipes are well casings made from PVC-U with reinforced walls, produced in accordance with DIN EN 1401-1, but with increased wall thickness and a minimum annular ri-gidity of 12 kN/m2. HS®-Pipes are available in the nominal sizes DN/OD 110 to DN/OD 630. In the nominal size area DN/OD 110 to DN/OD 250 pipes are produced sleeveless and are chamfered. They are available in lengths of 0.5 m, 1.50 m, 3 m and 5 m. Pipes with nominal sizes DN/OD 315 to DN/OD 630 have a moulded socket and a firmly inserted, oil-resistant FE®-Seal.
HS®-Pipes (110-250) are plain ended. This is the reason why there is no offset anymore in the socket area. The bar struc-

Pipes Pipes Pipes Pipes HS®-Pipe System – the components
Static attestationUnderground sewers and connections are exposed to static and dynamic loads from earth and live loads as well as exter-nal water pressure from ground water during the installation. DIN EN 1295 applies to the static attestation of underground sewers and connections, and in Germany the computation method according to ATV-DVWK-A 127 is used. From the filled in object questionnaire pipe statics are produced free of charge. Under usual installation conditions HS®-Pipes are designed for heights of 0.5 to 6.0 m above ground and simultaneous SLW 60 loads (according to SLW 60, HA Loa-ding, H 20-44). After consultation with the manufacturer pipes can be made available which meet even higher re-quirements.

The following rules should be taken into account:– Inward-sloped ditch is more favourable than
sheetment.– Horizontal ditch sheetment is more favourable than
vertical ditch sheetment.– The wider the ditch, the lower the pipe load.– Sheet pilings going down under the ditch bottom,
which are subsequently drawn, should be avoided, if possible, or must be taken into account statically.
– Installation in the stepped ditch is a special case. For this load case the minimum horizontal height offset and the maximum height offset must be known.
– For the connection zone a non-binding to weak-binding soil, which is capable of sealing, should be chosen.
– In the subsoil which is only capable to take a small load (e.g. turf) special measures should be taken, such as soil exchange or stabilisation of the connec-tion zone.

Fittings Fittings Fittings
FittingsThe HS®-Pipe System is equipped with a large number of fittings for the most diverse areas of application. They are wall-reinforced, like the other components. In this way pipes and fittings sustain high pressure loads and are suitable for coverings of 0.5 – 6 m for live loads up to SLW 60, HA Load-ing, H 20-44. The measured annular rigidity is ≥ 12 kN/m2. The root proof and root impermeable pipe connections are impact-resistant and can be fast and easily installed. All fit-tings in the nominal sizes DN/OD 110 – 250 are constructed so that no recesses are formed inside. By omission of shaped sockets the laying of HS®-Pipes becomes faster and more flexible.
The HS®-Pipe System has a broad range of fittings, such as a HS®-Access Pipe, HS®-Bends, HS®-Adaptors or HS®-VARIO Socket, which makes the connections flexible. The fitting which has received several awards is a useful supple-ment to the HS®-Double Socket. Specifics: The HS®-VARIO Socket has an adjustable socket. It enables the attached pipe

3-4 %. This is ensured by the continuous wall-reinforced and smooth execution of pipes and fittings. Most of the time, only the so called annular rigidity (SN 2 to SN 16) served as parameter for the resistance of plastic pipes to these loads. As the annular rigidity of a pipe or the one of fittings can be increased not only with more material input, but also through the most diverse patternings of the wall, it is merely
a construction feature. On the contrary, if a classification ac-cording to SDR is consulted, a clear statement can be made concerning the quality of pipes and fittings. Smooth pipe walls offer further substantial benefits: high resistance with regard to lumped loads due to substantially thicker walls, ideal compaction of the entire pipe bedding area, even right at the pipe, high degree of longitudinal stiffness.
Apart from the indication of the norm, the application area, the manufacturer name, the nominal size, the material, the stiffness class and other manufacturer information, accord-ing to DIN EN 1401-1 the wall thickness is also part of the minimum marking of pipes and fittings. The wall thickness is defined by the so called standard dimension ratio (SDR), which is the quotient determined from the nominal size/wall thickness ratio of a pipe. Based on this calculation the com-pact pipes and fittings made of PVC-U are classified in pipe series SDR 51, 41 and 34. The products marked SDR 34 have the greatest wall thickness because the following ap-plies: The lower the SDR value, the thicker the tube wall and the more stable the PVC-U pipe.
Mass equals classFlexible pipes are characterised by the fact that they evade earth and working loads through minor deformations. How-ever, in order to reduce pipe deformations to a minimum sufficient stiffness and robustness is required when using underground pipes. In the case of HS®-Pipes the deforma-tions to be expected even under high working loads or con-siderable installation depths do not exceed a maximum of

SDR SDR Chambers With the HS®-Demarcation Chamber and the HS®-Chamber System DN/OD 800 Funke has completed the current HS®-range.
Manholes DN/OD 800In addition to the control chamber, Funke offers a variety of modifications and developments for the most diverse appli-cation areas. These include the HS®-House Control Chamber as well as the HS®-Cleaning Manhole DN/OD 800 and the HS®-Flow Control Manhole, which add to the wide-rang-ing D-Raintank® for rain water infiltration. Decompression chamber, energy conversion chamber and pump chamber are other members of the new ”chamber family.“ With this, the user has a complete ”house-to-main-sewer“ system with excellent constructional characteristics. According to DIN EN
Everything under control
476, the HS®-Chamber DN/OD 800 belongs to the group of inspection chambers. Nevertheless, the inner diameter of 764 mm offers the operator very good site conditions for performing all the necessary operations from the upper edge of the surface, e.g. camera inspection, rinsing etc.
HS®-Demarcation ChamberAccording to § 45 Landesbauordnung NRW (Building Regulations of the Federal State Northrhine Westphalia), all private drainage and sewer systems must be checked for density until 31.12.2015 at the latest. In special cases the deadline for providing the requested proof has already expired on 31.12.2005. Reason enough to rely on Funke’s HS®-Demarcation Chamber in the professional development of the plot of land. The system allows fast and simple access to the canalisation in public and private areas without hav-ing to step on the plot of land, and offers the possibility to perform revision, rinsing, density control as well as realising barriers. The variants of the inspection chamber are provided in user friendly and installation friendly sets. The cast cover is available in load classes A/B (12,5 t) and D (40 t).

Soil compaction and soil surface sealing are generally the main reasons that many trees run out of air in our cities. The lack of soil ventilation as well as a decreased uptake of water and nutrients often lead to irreparable damage. The HS®-Tree Root Vent provides a solution. The product consists of segments from channel and pipeline engineering: A 160 to 230 mm telescopable cap with a slitted cover as well as a long plastic pipe of 1.50 m with soil anchoring. The upper part of the tree root vent has a diameter of 120 mm and is equipped with a UV resistant and slitted cover. The telesco-pable cap may be adjusted to the installation situation on site optimally. Furthermore, the upper part features a firmly shaped storage surface with a HS®-Connection Socket DN/OD 110. The lower part consists of long slitted standpipe with soil anchoring, 1.5 m in length. It is further equipped with a filter stocking.
Special-purpose solutions HS®-Tree Root Vent
The use of the new system ensures a permanent, sufficient supply of air and water to the tree roots. Moreover, it ena-bles checking of the root ball for damp traps. The inserted high load pipe absorbs live loads; a deformation in the tree grate area is therefore practically impossible. In addition, the firmly fitted filter stocking contained in the delivery program prevents the fine entry of soil into the pipe. A revision is realisable at any time, thanks to the practicable construction. Moreover, the vent pipe can be cleaned with a bore helix, when needed.

Special-purpose solutions
HS®-Drain Pipes were developed for use in infiltration facili-ties as pipe or pipe gravel infiltration ditches; for the drainage of street and track superstructures as well as fixed surfaces, such as airfields, athletic grounds, roads, park decks; and as drainage lines under increased requirements. Full drain, partly drain and multi-purpose pipes belong to the drain pipe product group. HS®-Drain Pipes are produced in the nominal sizes DN/OD 110 through DN/OD 630. The slot
HS®-Drain Pipes
image corresponds to DIN 4262-1 (Piping Systems for Civil Engineering subsoil Drainage: Plastic Pipes, 01.2001).
Because of the high annular rigidity of at least 10.5 kN/m2 (slit-ted), HS®-Drain Pipes are perfectly adapted for large and low heights above ground with simultaneous live loads. The theoretical long-time deformations are generally be-low 3% under ”usual“ constraints, the contingency reserves against stress and stability failures are considerably above the required values. Because of the even surface, HS®-Drain Pipes have excellent hydraulics characteristics. As opposed to corrugated pipes, e.g. commercially available land drai-nage pipes / k = 2.0 mm, the absolute roughness in smooth wall pipes made of PVC-U is 0.01 mm maximum. Especially regarding the danger of debris formation, smooth wall pipes provide an excellent solution. Further benefits include excel-lent chemical resistance as well as abrasion and high pressure rinsing strength.

HS®-Demarcation Chamber. Moreover, the fitting can be cemented in manholes to be used as closed conduction in water protection zones.
During the re-laying of channels the drainage fitting shows its strengths especially with direction changes. The construction of the aperture allows fast and easy laser installation for com-
petent setting of the further line run. It is equally easy to insert a shut-off bladder through the cleaning aper-ture for maintenance and shut-off. The placement of a
manhole structure is therefore no longer required.
The HS®-Access Pipe DN/OD 250 is provided with two firmly shaped socket and a cover dimension of 320 x 230 mm. A sealing of the annular space fixed in the cover provides a high density up to 2.4 bar according to ATV-DVWK-A 142. The cover, is connected to the lower part via a closure system sui-ted to construction sites. For easy opening of the cover, one of the three stainless steel pins at a sideward mounted pro-trusion can be attached and used as a lever. With the firmly inserted FE®-Sealing in the socket a pressing out, shifting or even forgetting the seal during laying is avoided.

Safe and economicalWith the new HS®-Pipe Cutting and Chamfering Device Drainage, Sewer, HS® or CONNEX pipes made of PVC-U in a nominal size range of DN/OD 110 to DN/OD 315 with a maximum wall strength of 15 mm can be cut to length and chamfered in one operation. It consists of an angle grinder that is firmly connected to a galvanised framework. The tool has a nominal power of 1500 watts as well as a 220 volt connection and is designed for cutting discs with a 150 mm diameter.
A cutting leave constructed especially for the application area provides a clean cross-section. Extractable roll carriages or auxiliary stands form a secure support for pipes in construc-tion lengths of 0.18 to 6 m. Because of the small weight of only about 25 kg, the pipe cutting and chamfering tool can be easily handled at the construction site. There is enough space in a car for this compact tool – the dimensions are 115 x 50 x 55 cm. In impassable or wet areas it can be set on a pallet to improve stability. In addition, a comfortable working height is achieved.

Recommendations for InstallationFor HS®-Pipes DN/OD 110 – DN/OD 630Upon installation of HS®-Pipes the European installation standard pursuant to DIN EN 1610 and – in addition – the ATV worksheet A 139 must be observed. Below is a summary of important recommendations for installation.
Ditch properties and conditionsThe stability of the ditch must be ensured by an appropriate sheetment, scarping or some other appropriate measure. DIN 4124 is applicable.
The ditch width must comply with the requirements of the static calculation. The minimum ditch width is determined by DIN EN 1610 para 6.1 depending on the nominal width, the formation of the ditch walls and the ditch depth.
The bed of the ditch must be executed observing the required slope and shape. If the natural ground does not have the car-rying capacity required, the bed of the ditch must be deepe-ned and a supporting surface made of compressible material must be provided. During construction works, ditches must always be kept free from water.
PipingThe pipeline zone is limited downwards by the lower bedding layer and upwards by the covering. The thickness of the lower bedding layer must not be lower than 100 mm under normal soil conditions. Minimum value for the covering is 150 mm above the pipe shaft and 100 mm above the pipe joint.
Suitable materials for the conduit zone are compressible, cohesive or weakly cohesive, in rounded or crushed form (cf. DIN EN 1610). Pursuant to DIN EN 1610 such building ma-terials must not contain any components larger than 22 mm (up to DN 250) or 40 mm (DN > 200 to DN 600). For HS®-Pipes, however, materials with max. granulation of 32 mm instead of 22 mm are permissible with nominal widths of DN/OD 110 to DN/OD 250 (see installation recommenda-tions, page 15). Do not use frozen building materials.
Piping works must start at the deepest point of the pipe-line section. Pipes must be aligned in terms of position and height on the lower bedding layer. When pipes and fittings are installed, surfaces of the spigot and socket areas must be clean. The lubricant must be applied to the sealing and the chamfering in a thin and even layer. Then pipes must be connected centrically towards the pipe axis. When pipes are cut to length the cut must be made precisely and at right an-gles with the axis. For trimming and chamfering the pipes we recommend the HS®-Pipe cutting and chamfering device.
The area of the pipeline zone must be filled and compressed on either side of the pipeline in regular layers. Alternatively, the simplified procedure described below is allowed for HS®-Pipes with nominal widths of DN/OD 110 to 250. The main filling must be carried out by layers. The individual dumping heights depend on the compaction device and the filling material used. Chart 4 of the A 139 ATV worksheet provides guide values with regard to the suitability, dumping heights and the minimum number of transitions depending on the type of compaction device. If required, the control of com-paction must be carried out by means of driving tests or plate load tests during the execution of construction works and in accordance with the static calculation.

Proposal with regard to the execution of the pipeline zone for DN/OD 110 – DN/OD 250 HS®-PipesDue to the SDR 34 wall reinforced execution of the HS®-Pipes and fittings we recommend a simplified installation according to the above shown diagram in addition to DIN EN 1610 for pipes up to DN/OD 250. The installation shown was scientifically examined and has proven itself over seve-rally years in use.
The creation of the pipeline zone has to be carried out care-fully according to the planning and the requirements de-termined by the static calculation. The pipeline zone must be protected against any alteration of the carrying capacity, stability, or position. For subsurface installation within the pipeline zone up to 30 cm above the apex of the pipe the following procedure is recommended:
1. preparation and compaction of the bed of the ditch (DIN EN 1610);
2. installation of pipes and fittings in the lower bedding;3. backfilling of the upper bedding layer with gravel, sand
or other approved construction materials in rounded or
crushed form as graded mixture 0 - 32 mm up to 10 cm above the apex of the pipe;
4. soil compaction using a light vibro-tamper (25 - 60 kg) laterally, at a distance of 10 cm on either side of the pipe;
5. backfilling up to 30 cm above the apex of the pipe using the above-mentioned construction materials;
6. compaction as described above along the entire covering of the pipe.
The misalignment of the pipeline conduit during compac-tion is avoided by immediate backfilling of the upper bed-ding layer up to 10 cm above the apex of the pipe. Lateral compaction at a distance of 10 cm on either side of the pipe ensures the compaction of the godet area is sufficient for the HS®-Drainage Pipe System. Increased wall thicknesses were chosen in order to facilitate the installation of HS®-Pipes and fittings by the user and to provide additional safety.
Leak testLeak tests of pipelines, chambers and inspection manholes have to be carried out using air (”A“ process) or water (”W“ process) pursuant to DIN EN 1610 section 13.
Special casesMultiple ditchIn the case of multiple ditches the minimum horizontal dis-tance between the pipes must be observed. Unless stated otherwise, this distance must be 0.35 m for HS®-Pipes pur-suant to DIN EN 1610.
Self-compacting backfilling materialsIn general, the use of approved self-compacting filling ma-terials (liquid soils) is allowed. If you wish to use such filling materials please contact us for technical clarification.

Installation in water protection areasFor the selection of the pipe system within a water protec-tion area, guideline ATV-DVWK-A 142 normally applies in Germany. Following is a summary of the most important provisions of that worksheet. Distinction is made between three protection zones:
• protection zone I (ground water collection zone)• protection zone II (narrow protection zone)• protection zone III (wider protection zone)
Pipes must not be installed in protection zone I.The conveyance of sewage water through protection zone II areas is permitted in exceptional cases. In such a case a double wall pipe system or a single wall pipe system for heavy duty use must be chosen depending on the poten-tial risks (i.e. dwell time between the base of duct and the well). Requirements include for example the tightness of the connections up to 2.4 bar test pressure, the observance of the minimum wall thickness of plastic pipes as well as high pressure flushing resistance and the precise fit of the sealing. Such requirements are fulfilled by the HS®-Pipe System.
Water protection areas
Slopes Where pipelines are installed in scarps, reinforced concrete or clay slabs have to be used in longitudinal pipe direction in order to avoid that the soil material along the pipeline is washed away and to give the pipeline more stability.
Concrete bedding and casingDirect concrete beddings or partial concrete casings are not permitted. If the use of concrete slabs in the bedding area is required due to constructional reasons, an intermediate layer of compactable soil having a height of at least 100 mm + 1/10 of the nominal width must be provided between the pipe and the concrete slab. Where the use of a concrete casing is intended, that casing has to be provided in such a way that it absorbs the complete static and dynamic loads.
Material loadHS®-Pipes made of PCV-U are supple and show a carrying behaviour that is different from that of deflection resistant pipes such as vitrified clay or concrete pipes. While loads are concentrating above the pipe in the case of deflection resistant pipes, great part of the earth and traffic loads is transmitted to the surrounding soil. Where loads are higher than foreseen, or if the load situations changes in the course of time, the only result would be a minor deformation of a supple pipe while in the case of deflection resistant pipes stability failure and thus the rupture of the material cannot be excluded.
This means that a low elastic modulus must be compensated by increasing the wall thickness in order to obtain the same annular rigidity. The elastic modulus is a characteristic value of the material describing the connection between tension and elongation when solids are deformed with linear elastic behaviour. Therefore, the elastic modulus represents an in-dicator of the solidity of the material. The annular rigidity or flectional resistance of a smooth-walled pipe (SN classificati-on) is depending on the elastic modulus (short term) and the wall thickness of the material. Due to the different elastic modulus values wall thicknesses of PVC-U pipes are significantly smaller than in the case of PE or PP pipes. This means that the diameter/wall thickness ratio (SDR) is higher with the annular rigidity of the pipe being the same or even better and thus advantages of pipes and fittings made of PVC-U with regard to their lower weight and material costs.
Installation under frosty conditionsExternal opinions have shown that HS®-Pipes may be in-stalled under frosty conditions with temperatures of up to -10°C. With temperatures below freezing point it must be ensured that the backfilling material pursuant to DIN EN 1610 is not frozen.
In protection zone III single wall sewer pipes and drain chan-nels pursuant to the applicable standards and guidelines are normally sufficient. Like in protection zone II the gen-eral planning principles pursuant to section 3.2.3.1 must be observed.

The hydraulic dimensioning of gravity sewer channels will be carried out pursuant to the ATV worksheet A 110 ”Hydraulic dimensions and efficiency of sewage water channels and sewer pipes“ published in the August 2006 edition. Evidence is given according to the global or individual concept. For the dimensioning of sewage water channels still to be built, it is normally the global concept that is applied. The various loss factors are allowed for in the operational roughness kb. Due to the particularly low wall roughness of plastic pipes, rough-ness values of kb = 0.25 mm for straight channel sections or
kb = 0.4 mm for normal channels with lateral supplies are recommended and determined.
The following charts show the values for HS®-Pipes DN/OD 110 – 630 (wall-reinforced, annular rigidity measured min. 12 kN/m2) for kb = 0.4 mm. In the case of straight channel sections of kb = 0.25 a slightly higher hydraulic performance (approx. 4 - 5 %) can be expected.

Impact test pursuant to DIN EN 744The resistance of the pipes against external impact stress is tested pursuant to DIN EN 744. Test pieces in the form of pipe sections are exposed at 0°C to the impact of a falling weight, that falls onto the test piece in determined positions distributed over the circumference from a pre-determined height. The impact surface of the drop weight is the shape of a ball. In the case of nominal pipe width DN/OD 250 for
Tightness of pipe connectionThe tightness of pipe connections is tested pursuant to DIN EN 1277. Three conditions are examined: condition A (without deformation and bending), B (with deformations pointed ends 10% and sleeve 5%) and C (bending 2°). The tightness of HS®-Pipe connec-tions is evidenced by an independent test centre for all three conditions both with an air depression of -0.3 bar and for an increased water internal pressure of 2.5 bar.
12,5 kg from a height of (-10°C)Installation up to -10°CIn order to determine the suitability of the pipes for instal-lation at temperatures below freezing point, smooth-walled pipes offer the possibility to carry out the step test pursuant to EN 1411 in addition to the test method pursuant to DIN EN 744. During that test, test pieces in the shape of pipe sec-tions will be exposed at 0°C to the impact of a drop hammer the impact surface of which is also spherical. The weight of the drop hammer depends on the fall height which will be in-creased until a test piece fails the test, the maximum increase being 2 m. For the examination of the nominal width pipe DN/OD 250 the weight of the drop hammer is 12.5 kg. Fol-lowing successful testing (external test certificate) the HS®-Pipes are marked with the corresponding ice crystal symbol and may be installed at temperatures of up to -10°C.
instance, this would mean that the test piece is subjected to the impact of a falling weight of 2.5 kg from a height of 2 m at 0°C.

Diametrical load testThe annular rigidity S of a pipe is a characteristic value describing the resistance of an annulus against external strain. This is the basis of the classification into SN classes 2, 4, 8 and 16. The annular rigidity is determined through the diametrical load test pursuant to EN ISO 9969 where a pipe section of 30 cm length is positioned between two parallel arranged panels and charged at a defined constant speed. The amount of force necessary to create a deformation of 3 % of the pipe wall diameter forms the basis of the deter-mination of the annular rigidity.
High pressure jetting resistanceThe most common type of channel cleaning is the high pressure flushing. The jets of water coming from the flushing nozzle under pressure re-move deposits which are then transported as suspen-sion to the starting duct. The pipe material must stand the strain caused by the water jets hitting the pipe walls. In corresponding tests carried out by the Civil Engineering Of-fice of the city of Zurich it was shown that channels made of asbestos cement, concrete, PVC and PE-HD were not damaged with a water pressure at the nozzle of 120 bar (1740 psi) and a water volume flow of 300 l/min. HS®-Pipes were tested by the IKT pursuant to DIN V 19 517 at a flushing pressure of 240 bar (3480 psi). Result: passed!
Diametrical load test: annular rigidity ≥ 12 kN/m2 / ≥ 16 kN/m2

QS QS QS QS QS QS QSBehaviour under long period stressingThe test of the long-time behaviour of the internal pressure is a method of testing the life expectancy of a pipe system. During this test, the serviceable life of the pipes under differ-ent ambient temperatures (water bath) and internal water pressure is determined. The calculation of the pipe‘s service-able life to be expected is based on the results from these tests. The behaviour under long period stressing of HS®-Pipes is evidenced regularly. The expected service life of HS®-Pipes made of PVC-U is 100 years.
A hard nut to crack for rootsSubstantial part of the German sewer network is damaged resulting in damages to our environment and high environmental clean-up costs. A large pro-portion of such costs currently arising is due to the low-quality construction work or to hurtful environ-mental impact. High-quality products and the pro-fessional execution of construction works in connec-tion with waste water channels and sewers can exert a positive impact on such a development. Therefore,

the long-term and safe protection against the pen-etration of roots must be ensured by using drainage pipe systems used in the construction of housing es-tates. The assessment of a unique pot experiment carried out over 10 years by the Landwirtschafts-kammer Rheinland (Chamber of Agriculture) in the Essen Gartenbauzentrum (Horticultural Centre) from 1996 to 2007 provided evidence that HS®-Pipes and fittings are root proof.
Funke quality: Made in GermanyAt Funke Kunststoffe GmbH PVC-U and other polymeric materials are processed. The thermoplastic deformation of the material allows for a quick development of homogeneous fittings and pipes as well as profiles for constantly changing fields of application. This is the basis of modern and highly efficient constructional solutions to the benefit of municipal clients, network operators and civil engineering companies. Users from the water and waste water management sector require efficient products and praxis-oriented, economical solutions. Solutions provided by Funke‘s complete range from sewer connections through to the main sewer.
Great part of the products launched by Funke over the last few years in the waste water treatment or rain water infiltra-tion sectors has been developed in close co-operation with companies involved and municipal clients. The result: flex-ible solutions for various civil and underground engineering works both in terms of technology and economy. Products used - such as pipes and fittings from the HS®-Drainage Pipe range comply with the most demanding quality standards. The entire production of pipes is regularly controlled by our own and by external laboratories. Such controls apply both to the base material and the finished product and contribute to safe, efficient and economical processes on site and to the business partner‘s satisfaction.
22
Tested qualityThe products developed and produced by Funke comply with the highest quality standards. This is evidenced by nationally and internationally acknowl-edged certification reports and test certificates awarded by external test laboratories and independent institutes including the Materialprüfungsamt MPA (Material Testing Laboratory) Northrhine Westphalia and the IKT Gelsenkirchen. The company is certi-fied according to ISO 9001.
In addition, most Funke products have obtained the general technical approval of Deutsches Institut für Bautechnik (DIBt) (German institute for structural engineering), including the pipes and fittings of the HS®-Drainage Pipe Sys-tems. The general technical approval is awarded for such building products and building types, with regard to which there are normally no generally acknowledged technical rules and in particular DIN standard or which devi-ate from these substantially. They rep-resent reliable evidence of usability of construction products or applicability of building types with regard to con-structional requirements concerning buildings. A decisive aspect: the general technical approval means additional se-curity both to the client and to users.
