Markets &ApplicationsThere is extensive use of Weber’s PrecisionGrouts within the civil engineering market.These high performance products can beused in any situation where accuracy inalignment is essential or where transfer ofdynamic or static loads are required.

These include:

• Bridges

• Highways

• Railways

• Theme Park Rides

• Building Structures

• Crane Rails

• Machine Bases

• Wind Farms

Precision GroutingEquipment and machinery which have precisetolerances for alignment or require uniformsupport cannot be placed directly on finishedconcrete surfaces. Both the concrete surfaceand the machine base have irregularities whichresult in alignment difficulties and bearing loadconcentrations. For this reason, machine basesor soleplates are aligned and levelled byshimming or other means and the resultingspace between the machine base and thefoundation is filled with a load transfer material.The load transfer materials most frequently usedare hydraulic cement and epoxy grouts.

After placement and hardening in the spacebetween a machine or equipment base andthe foundation, the grout is expected toperform one of the following functions:

1.Permanently maintain the original level and alignment of the machinery orequipment and transfer all loads to thefoundation when shims and other temporaryposition devices are removed.

2.Provide lateral support or corrosionprotection for shims which are designed to transfer all loads to the foundation. Some grouts are also required to provide sound deadening and a mechanism for reducingvibration. This can often be achieved by acomposite system incorporating elastomericbearings and a structural adhesive.

All products are CE marked where relevant.Declaration of Performance documentation(DoP’s) are available online atwww.netweber.co.uk or on request.


The most important requirement for a groutwhich is intended to transfer loads to thefoundation, is for it to have volume changecharacteristics which result in complete andpermanent filling of the space. Plain grout,consisting of cement, aggregate, and water,does not have those characteristics. Severalother properties of the grout such as consistency,strength, chemical resistance, and compatibilitywith the operating environment are alsoimportant. However, these properties areobtained more easily than the necessary volumechange characteristics.

For most applications, the space between thefoundation and the machinery or equipmentbase can best be filled by pouring a grout intothe void. A plain sand / cement grout with thisconsistency could be placed in the space andmay develop adequate strength. However, afterplacement, the sand / cement grout will losecontact with the plate because of settlement,shrinkage and bleeding.

The result will be an incompletely filled spaceleaving the equipment resting primarily orcompletely on the shims or other alignmentdevice. To maintain permanent contact with theplate, a grout must be formulated using specialadditives with cementitious or epoxy systems.These grouts have a high proven EBA (EffectiveBearing Area), which is the actual area ofcontact under a bearing plate, free of airbubbles and voids.

Primary Functions of Bearing Grouts

5www.netweber.co.uk

Application of Precision GroutsThere are four main methods used to groutbaseplates:

1.Pouring from one open side of a shuttered baseplate

2.Pouring through a hopper or pipe down adrilled hole in the top of the baseplate

3.Where the gap is very narrow under smallbaseplates (up to 300 x 300mm), it is possibleto inject grout through a standard mastictype of gun.

4.For larger baseplates it is better to use apump to deliver adequate volumes of groutto the point of grouting. (For epoxy grouts, a peristaltic pump is used. For a cementgrout a more conventional diaphragmpump is commonly used)

Where large areas need to be grouted, orwhere complex bases are involved, it is wise todesign a method of introducing the grout toeliminate air entrapment under the baseplate.

How to Select a Grout

Size of BaseplateThe size of baseplatedetermines the method ofapplication. Grout canusually be poured under asmall baseplate, but needsto be pumped under a largerplate or where there is noaccess for pouring.

Dimensional StabilityAll grouts must be non-shrink or shrinkage compensated.Grouts should also havethermal movementcharacteristics sympatheticwith their immediatesurroundings.

Resistance to ChemicalsGrouts should be resistant tooils, greases and certainsolvent chemicals as well assalts if used in marineenvironments.

DurabilityGrouts must be resistant to deformation so they allowintimate contact between the bearing and foundationand must have a life expectancy of at least 10 years.Most resin grouts are more durable than cement groutsespecially in dynamic loading situations and although theinitial cost is more, their service life makes them more costeffective in the long term.

Effective Bearing AreaThe main function of a grout is totransfer load. A grout must providean effective bearing area (EBA) of atleast 90%. EBA is affected by poorgrout flow, air voids, air entrainmentin the grout, and poor design of thegrouting operation.

Return to ServiceMany grouts are rapid settingto allow earlier return toservice but often thesegenerate exotherms that canreduce working time andaffect grout integrity especiallyin thicker sections.

Gap SizeIn most circumstances, gapsbetween 15mm and 50mmcan be grouted with ease.Thin gaps, less than 5mmshould be avoided as it isdifficult to transfer loads oversuch a limited section. Someepoxy grouts and structuraladhesives are designed foruse in these thin sections butthe method of applicationneeds careful consideration.

StaticStatic loads impart less stress onthe grout and in such casescement grouts can be used forgaps under columns andstanchion bases, holes, cavitiesand general infill operations.

The choice of suitable material depends onthe intended usage, accessibility, thickness ofbed and the area to grout.

For dynamic loading: (e.g. motor, turbine orunder heavy wheeled traffic - crane rails) -epoxy grout must be used.

For static applications: (e.g. such as understanchion bases, columns etc.) - both epoxy and cement grouts can be used, but cementitious grouts are more popularbecause they are perceived as being morecost-effective.

• Cementitious Grouts - provide resistance to salt and sulphate exposure and can withstand high operating temperatures.

• Epoxy Grouts - provide better resistance to impact, vibration and chemicals andhigher compressive, flexural, tensile andbond strengths.

A precision grout is a liquid mortar. The mainfunction of a precision grout is the effectivetransfer of load from the structure or machineto the foundation. In order to enable this, thegrout must provide adequate permanentbearing, be non-shrink and have sufficientstrength to resist any loading imposed upon it.To get the grout into place, often into smallgaps or confined areas, the grout must besufficiently fluid so it can flow or be pumped,but it must be stable and not be prone tosegregation.

DynamicDynamic or impact forces cancause cracking or fatigue failuresin cement grouts and in suchcircumstances it is always betterto specify and use epoxy-basedgrouts.

Anchoring & Fixing

Deep Bay Link North Segmental Bridge Project, Hong Kong

Complementary to the support ofbaseplates by the Weber Precision Groutrange are grouted anchors and structuraladhesives.

Anchor Grout

A bonded or grouted anchor is fixed by themechanical key between the bolt or bar, theanchor grout and the drilled hole. The primarymechanical key is created by drilling a roughsided hole using a rotary percussion drill,secondary anchorage is achieved by thebond between grout and anchor, meaningloads or tensile forces are transmitted throughthe grout to the substrate.

When a tensile force or ‘pull-out’ load isapplied to the bolt or bar, it creates a shearforce in the substrate. As most substrates are

relatively weak in shear and tension, it isnormally the strength of the substrate and thedepth of the anchor that determines theultimate strength of the bonded or groutedanchorage. The choice of the right anchorgrout depends upon the application and pull-out loads to be applied.

Structural Adhesive

Glued segmental construction involves the useof a high-strength epoxy adhesive to bondpre-cast elements together. Segmental bridgeconstruction is a popular technique whichspeeds up construction of viaduct structuresbecause it avoids the expense and trouble offormwork supports.

In addition to reduced construction time andcost, structural adhesives offer benefits in theform of:

• High bond between the concrete surfacesto transmit compressive, tensile and othershear forces

• Early strengths over a wide temperature range

• Waterproof joints along the cross-section to which they are applied

High-performance epoxy adhesives and resinsare also used for the application of compositestrengthening plates and wraps.

THORPE PARK’S new adrenaline-inducing theme park ride, THE SWARM, is the UK’s first winged rollercoaster and sets abenchmark in ride experience.

The dynamic load of 28-rider trains travelling at up to 100km perhour, on 1000 tonnes of track over a distance of 775m (2,543 ft), is supported Weber’s high performance precision grouts.

This enormous structure and the ground bearings are subjected to very high dynamic loadings generated by the fast and furious winged ride-cars. HBL Structural Engineersspecified weber.tec EP Pourable Grout to fix the steel mountingsto the concrete ground bearings that absorb these high loads.Selecting a material for fixing the plinth anchorages and theshear key anchorages had two main criteria; it had to have the ability to sustain high dynamic loadings and to transfer thestress from the structural steel components back into theconcrete bases.

Product: Five Star Grout SPFive Star Repair Concrete CP

Specifier: Ove Arup


Project: The Millennium Bridge, London

Designed by Ove Arup, the bridge features low slungsuspension wires that make the bridge seem, intriguingly, to defy gravity. This seemingly light aesthetic designdisguises the fact that the same if not a greater load thantraditional designs needs to be safely transferred to thesupporting structure.

Five Star Grout SP was chosen to support the full weight of the structure via the bearings to column piers whilstFive Star Repair Concrete was used as the concrete tostrengthen the caisson plinths.

The high performance precision grouts feature non-metallicchemistry so avoiding potential dimension instability,corrosion or staining in the future.

Reliable transfer of load from the structure to supportingfoundations is a vital element of design in any Civil Engineeringproject especially where high static loads and the transport ofthe public are part of the equation. Due to its long servicerecord of reliability in use, Weber Five Star Grout SP was chosenby the contractors McAlpine to carry out this crucial role.

Five Star Grout SP had to perform in the confined spacebetween the superstructure of the fabrication and theconcrete foundations that support it. In this vital but restrictedarea it is important that full contact with all bearing surfaces isachieved, with no air voids or shrinkage.

Five Star Grout SP is usually poured or pumped as a flowinggrout into such areas. On setting and curing the material isslightly expansive and has thermal movement characteristicssimilar to the supporting concrete.

The exclusion of any metallic based elements from theformulation eliminates any possibility of subsequent problemssuch as dimensional instability, corrosion or staining.
