Will not discolor concrete orproduce electrolytic actionFIELDS OF APPLICATIONPOLYSTOP waterstops are used in conjunction withexpansion and construction joints in rccstructures like:4 water reservoirs & storage tanks4retaining walls, basements, foundations4subways, tunnels & culverts4drainage, sewerage & waste water structures4treatment plants4swimming pools4dams, canals INTERNAL PROFILE DETAILSPOLYSTOPICJ- Internal Construction Joints the internal construction joint waterstops isplaced in the centre of the concrete constructionjoints. since this type of waterstop is embeddedinto the concrete they are designed andincorporated with fins and multiple solid-core ribsalong the two lengthwise edges.

3 These finsinterlocks the waterstop in the concrete thusproviding a superior mechanical bond with theconcrete. the ribs are designed with particularangle which anchors with the concrete and furtherreinforces the mechanical bond. in addition to thatangle in the ribs ensures a torturous path for thepassage of Internal Expansion Jointsthe internal expansion joint waterstop is placed inthe centre/internal section of the concreteexpansion joint. this waterstop has a centralhollow bulb which is designed to allow the cyclicaland differential movement in both lateral andtransverse direction without excessively stretchingthe material. for greater versatility and superiormechanical bonding, the waterstop isincorporated with multiple ribs and fins on boththe lengthwise edges.

4 EXTERNAL PROFILE DETAILS POLYSTOPECJ- External Construction Joints external construction joint waterstop is used atjoints of slab on grade or walls that gets backfilledon vertical walls. the profile of this waterstop is flatwith multiple ribs and fins along its flanges forbetter mechanical bond or interlock in External Expansion Joints external expansion joint waterstop is used inconcrete expansion or isolation joints. these aredesigned with centre bulb with a tear web. thesetype of waterstop is used where large movementsin expected. tear web keeps concrete out of thebulb during concrete placement. upon jointmovement, the thin tear web ruptures allowingsubstantial mechanical deformation of center bulbwithout stressing the INSTRUCTIONS fixing internally:internal and centrally placedwaterstops are positioned within the concretewhere the centerline of the waterstop is alignedwith the centre of the joint.

5 Such waterstopsfunctions as a watertight diaphragm wall againstany water leakage. for a proper placement of thewaterstop, split formwork is recommended wheninstalling in slab-to-slab, slab-to-wall and wall-to-wall joints. the waterstop is then tied with wirestrough the eyelets provided at the end flanges tothe reinforcement. this will ensure that thewaterstop firmly held in position and is notmisaligned or fold during the concrete pour. onehalf of the waterstop has to be positioned withinthe first pour and the other half projecting into thesecond pour. a tight fit between the waterstop andthe form is also necessary to prevent excessiveleakage of concrete paste, which could lead tohoneycombing of the externally:the externally placed waterstop isinstalled prior to pouring of concrete .

6 The externalPPOLYSTOPOLYSTOP2expansion joint profile is usually loosely laid on topof the compacted grade or mudslab. the stop endform works are then fixed on top of the waterstop can either be nailed or glued intoposition to avoid displacements during theconcrete pour. the external construction jointprofile is glued or nailed on to the vertical waterstop is so positioned that only the ribbedside is embedded into the :a fully continuous water stop network mustbe formed throughout. at bends and additionaljoints, factory welded junctions are to be used whenjointing with the placed water stops. field buttsplicesshall be heat fused welded using an appropriatewelding knife of voltage ranging between 220-240V(ideally with thermostatically controlled).

7 Theedge of the water stop shall be cut with a knife toget an even and sharp finish and aligned in aspecially designed fixing edges will then bepositioned in the jig in such a fashion that at least25mm of water stop protrudes from the jig. placethe welding knife in between the two ends, and whenthe pVc starts melting (>140 c), beads will startforming around the section. remove the weldingknife and press both the ends firmly against eachother to form a neat buttsplice. press the jointsagainst each other for sometime till the pVc coolsand forms a strong fusion welded concrete in and around the waterstop has tobe properly compacted in order to ensure a fullcontact of the waterstop and a water tight seal. 2.

8 Surface of the waterstop shall be cleaned of alldirt and cement laitance which can affect thewater tight seal with the the clearance between the waterstop and thereinforcement should be at least twice that ofthe maximum size of the aggregate. this willprevent the formation of voids and honeycombaround the waterstop. 4. the waterstop should not be punctured toallow a reinforcement to pass through thewaterstop. 5. installed waterstops should be protected fromuV. prolonged exposure will make the pVcwaterstop the material in a cool and shaded from uV and high temperatures. prolongedexposure to sunlight and harsh environment willresult in deterioration of the product. keep awayfrom sharp edges to prevent damage.

9 HEALTH & SAFETYPOLYSTOPis completely non-hazardous and non-flammable. But care should be taken while cuttingand welding the joints. hydrogen chloride vaporswill be released during the hot welding, thereforethe working area should be properly SPECIFICATIONSUPPLYPROPERTIESVALUESTESTS TANDARDSW idth, (mm) 150, 200, 250 Web thickness, (mm) 4, 10specific Gravity* strength,* 15 Bs 2782(n/mm )elongation, (%)* 300 Bs 2782shore a hardness* 80 5 astM d 2240Bs softness*40-50 Bs 2782resistance to water nil Bs en 12390pressure @5bar* water absorption*, (%) < astM d 570chemical resistance* ph to astM d 543suitability with passespotable water * (non toxic) Bs 6920standard compliance Bs 2571, crd-c 572-74all values given are subject to 5-10% tolerance.
