JOINT TYPESCONSTRUCTION JOINTSAs their name implies, these joints are used to simplifyconstruction; they are not intended to accommodatemovement. Nevertheless, cracks tend to develop at breaks inconstruction whether wanted or not, so construction jointshave to be designed with cracking in mind; for example a PVCwaterstop placed over the blinding and cast into a basementfloor.EXPANSION JOINTSThese create a gap in the structure to allow for bothexpansion and contraction caused by thermal and moisturemovements. These joints are usually formed by installinga compressible filler board between sections. ‘Settlement’joints are included under this heading - or any joint designedto take up such movement. Locating expansion jointsdemands careful thought, considering not only the spacingneeded to avoid cracking but also a pleasing appearanceand access for subsequent maintenance.TYPICALAPPLICATIONSEvery sizeable concrete retaining wall, basement slab, reservoir tank, length of tunnel musthave joints. These may be a mixture of construction or expansion joints but all such joints indirect contact with water need the protection of a waterstop.The waterstops can be hydrophilic or impervious PVC strips which are cast into the concreteat the joints to prevent the passage of water.To cater for every application, Fosroc have a portfolio of Supercast PVC and Swellablewaterstops which have been successfully installed all over the world for many decades.6WWW.FOSROC.COMCONTRACTION JOINTSThese are for relieving shrinkage stresses induced inconcrete as it sets; stresses that would otherwise causerandom cracking. A contraction joint may be designed as acomplete break in the structure, each cast butting againstthe previous one. If more structural stability is neededbetween sections the reinforcement may be continuedacross the joint to restrict its opening. Forming grooves inthe concrete surface - top, bottom or both - makes anotherkind of contraction joint to induce cracks to form alongpredetermined planes of weakness. A waterstop may beincorporated into such joints.WWW.FOSROC.COM7
SUPERCAST PVCWATERSTOPSTo ensure a firm fix, corporate a row of eyeletsalong both edges for wiring tonearby steel reinforcement.Fosroc Supercast PVC waterstop profiles have beendesigned with high performance at their core. Theseprofiles capture the best principles of PVC waterstopengineering utilising tortuous path ribs, correct bulbshapes giving excellent sealing effect acting as valves,eyelets for secure placement and sloping web thicknessto avoid cracking.Make sure that there isadequate clearance betweenthe waterstop and surroundingsteel reinforcement for wiringand to ensure good compactionof concrete.For over four decades Fosroc Supercast PVCwaterstops have been installed in many projectsthroughout the world achieving assured long termperformance even in extreme conditions, resulting inprevention of unwanted water penetration.When sealing joints in watertank roofs it is not alwayspractical to install a centrallyplaced waterstop. An externallyplaced bandage strip such asFosroc Expoband H45 is idealfor this application. HydrocellXL joint filler board andNitoseal MS600 joint sealantscomplete the system.Fosroc Supercast Rearguard R and S PVCwaterstops have an “outboard” flange alongeach edge for nailing to the formwork or blindingconcreteENGINEERED SOLUTIONSFosroc Supercast PVC waterstops allow freshly poured structural concrete to flow around them. However, designs thatinclude large congested ribs can create confined spaces and lead to a restriction in the concrete flow which could limitcompaction and the interlocking process between the waterstop and the concrete.Beware of ultra-flexible and relatively loose PVC waterstops which can be easily displaced upon pouring of fresh concrete.Fosroc Supercast PVC profiles are flexible, elongation 300%, but suitably firm (Shore Hardness between 80 - 90).Valve PrincipleEyeleted FlangeThe eyeleted reinforced edgeflange enables the waterstopto be easily positioned bywiring to the surroundingreinforcement.Tortuous Path PrincipleComplex cross sectionpresenting a much greaterresistance and more difficultpath for water to seep aroundthe section8WWW.FOSROC.COMDrying Shrinkage of ConcreteWhen drying shrinkage takesplace, the edge bulbs of theprofile act as anchors, inducingtensions across the waterstopthereby resulting in a sealingeffect at the inner faces of theedge bulbsSloped Plain ProfileThe plain slope in the centreof the waterstop is directedalong the concrete movementdirection to avoid cracks in theconcrete edges and to maintainperfect interlockFosroc Supercast PVC waterstops are manufacturedto the highest quality standards in factories that areISO 9001 and ISO 14001 quality assured.These waterstops when combined with FosrocProofex membranes and Nitoseal joint sealantscontinue to give clients around the world piece ofmind, with compatible systems providing structuralintegrity ensuring long term performance.WWW.FOSROC.COM9
SUPERCAST PVC PROFILESWatafoilSUPERCAST TWINSTOPWhere high water tables exist in deep basementconstruction and the highest possible watertightdesign is required, then use Fosroc Supercast Twinstop.XHD Rearguard RHydrofoilFosroc Supercast Twinstop is a combined PVC andhydrophilic waterstop for extra protection. The PVCprofile performs as normal but when water reachesthe hydrophilic inserts, they expand to form a sealedbarrier.XHD Rearguard SXHD WatafoilThe hydrophilic inserts are based on Fosroc’s basicpolymer swellable compound which is post-insertedinto the PVC waterstop meaning there is no chanceof pre-swell prior to concrete casting.

Fosroc supply jigs andheating blades suitable for making simple butt joints on site.Although it is possible to weld mitres and corners on site it is advisable to purchase factory-made intersections from Fosroc,then to butt-weld these to the standard rolls of waterstop on site. This method speeds up installation and means that onlysimple straight welds are required. Intersections available include those of dissimilar profiles e.g. Supercast Watafoil toHydrofoil or Supercast Rearguard S to Hydrofoil.For complex geometries or repeated shapes, special bespoke fabrications can be supplied.

SUPERCAST PERFORMANCEWet/Dry Cycle PerformanceVolume Swell PerformanceFosroc Supercast SW waterstops are designed forconsistent long term performance throughout thelifetime of a structure. Their superior polymer basisallows them to expand and contract consistentlyover multiple wet/dry cycles ensuring that waterpassage is arrested.SUPERCAST SWELLABLEFosroc Supercast SW waterstop strips use basic-polymer hydrophilic technology which allows them to swell on contact withwater creating a positive pressure against the faces of the joint thus preventing the passage of water.The main advantage they have over conventional PVC waterstops for non-movement joints is that they provide a problemsolving solution for applications where, traditionally, complex formwork would have been required. They provide anexcellent solution for pipe entry sealing and also do not require hot welding on site.Fosroc Supercast SW waterstops may be used for the integral sealing of construction joints. However due to the fact theymust be fully restrained to function properly, they should not be used in movement joints. In this instance a traditionalFosroc Supercast PVC waterstop with expansion profile designed to accommodate movement should be used.There is a myth that the greater the swelling % thebetter the swellable waterstop. This of course is wrongbecause the main measures of success for a swellablewaterstop are based upon;1) Wet/dry cycling long term performance2) Ability to resist water pressure shortly afterconcreting3) Ability to resist water pressure for the life of thestructureSUPERCASTSW105mm x 20mm strip for usewhere steel reinforcement iscontinuous through the joint14WWW.FOSROC.COMSUPERCASTSW2010mm x 20mm strip for allconstruction joints, waterpressure resistant up to 100mSUPERCASTSW3010mm x 20mm strip for allconstruction joints, waterpressure resistant up to100m, special salt water gradeextra swellFosroc Supercast SW strips gain swelling pressurequickly after concreting and typically achieve anequivalent water pressure resistance of 6 bar after 1day.Full watertighness testing has been carried out on aspecially designed test rig designed to simulate a reallife construction joint sealed with Supercast SW20/30.Positive water pressure is applied to the simulated joint,and is increased up to a maximum pressure of 10 bar(equivalent to 100m hydrostatic head). The joint can beopened to simulate a crack in the construction joint,and the Supercast SW20/30 tested for watertightnessat increasing gaps. Both Supercast SW20 and SW30 areindependently tested achieving 10 bar results even upto 3mm gap.WWW.FOSROC.COM15
SUPERCAST PREDIMAX INJECTIONHOSE WATERSTOPSFosroc Supercast Predimax injection hose waterstops are designed to provide a means for future sealing of cracks inconcrete. They are fixed into the construction joint in a central position with a minimum of 80mm concrete cover. The fixingclips are positioned at 150mm spacing. Hoses are overlapped at junction locations and terminated at the surface in junctionboxes.Fosroc Supercast Predimax is available in 2 sizes, 11mm and 19mm external diameter. For multiple injection you shouldfirst inject with cement, then micro cement then finally PU resin. The injection process should not commence prior to 6weeks after the concrete has been cast, to allow for shrinkage and settlements.INJECTION METHODOnce secure connections have been made, begin the injection process. Fill hose with suitable injection material until itemeges from the opposite end. Clamp the end shut.Start injection at a pressure of between 75 and 150PSI. Once the injection material has filled the joint area and is no longerflowing, gradually increase the pressure to a necessary delivery volume of between 500 and 600PSI.Maintain this pressure for approximately 3 to 5 minutes, allowing for injection material to thoroughly penetrate the jointarea.Once maximum pressure of 500 - 600PSI is held for the designated period of 3 - 5 minutes, disconnect the pump from theinjection vent and begin the connection process for injection at the opposite vent end; clamp the first injection end first.Reinject the hose from the opposite end within the gel time of the injection material.Disconnect the cap from the vent ends. Connect a vacuum pump to either one of the vent ends and place the other end intoa bucket filled with water.Commence the vacuum process. The outer tube of the hose will close the injection ports and the remaining residual injectionmaterial will be removed from the interior of the hose. Then flush with water.Predimax 11As soon as the water flow is clean on the vacuum side, disconnect the water supply by removing the vent end from thebucket of water. Disconnect the vacuum pump and close the injection vent ends and secure tightly with screws.Predimax 19Predimax 19Hot-shrinking hoseVentlating hosered/whiteHose clamp withdowel/withoutdowelSealing plugyellowHose clampØ 20mmVentlating hosered/whiteHot-shrinking hosePredimax 19Pressing nippleInjection nippleBinaural clampBinaural clampVentlating hosered/whitePressing nippleInjection nipple16WWW.FOSROC.COMWWW.FOSROC.COM17
BELOW-GROUND WATERPROOFINGFosroc offers one of the most comprehensive ranges in belowground waterproofing, providing leak-free buildings around theworld. These systems are manufactured to the highest qualitystandards backed by independent test certificates.For below-ground structures where the exterior face of thestructural concrete is inaccessible, the waterproofing must beapplied prior to pouring the concrete. Conventional systemsare either loose-laid or self-adhering to the substrate not thestructural concrete, this means there is no seal between thewaterproofing and the structural concrete which can lead towater travelling between the waterproofing and the structurefrom any leakages that may occur. BS8102:2009 highlights thisproblem and recommends that a fully-bonded pre-appliedwaterproofing system be used to mitigate this risk. A similarproblem occurs where ground settlement takes place.Proofex PGP / Alkorplan, a loose-laid PVCmembrane system, is available in large rolls.Joining is realised through welding with hotair. Compartments can be laid out usingSupercast PVC waterstops which are weldedto the membrane.The Nitoproof liquid-applied coatings rangeprovides protection for foundations or fordampproofing, they are easy to apply andare available in a wide range of grades.SupercastPredimaxinjectionhosewaterstops for future provision of sealingleaking joints.Nitocote CM210 provides an excellentsolution for waterproofing the outside orinside faces of basement walls and floorsdue to its ability to withstand both positiveand negative water pressure.
