Prefabricated Waterstop for Circular TanksWhen Extaseal waterstop is required to be prefabricated to form a circle the details below can be used as adesign guide to establish the number of chords required compared to the deviation obtained from a true circle.

Where the circular waterstop is placed on blinding sloping towards the centre the number of chords may bereduced. Where the radial joints are required the number of chords used should be divisable by the number ofradial joints.

Circle Radius No. of Chords Deviation from aTrue Circle.

PVC Waterstop Jointing Detail

19

1 Using a sharp knife cut both endsto be welded straight and square (use jig as guide)

2 Locate waterstop in jig, withapprox. 25mm protruding. square jig with clamp.

3 Insert hot blade

4 Push waterstop ends against blade

5 Maintain contact until plastic melts into bead of about 5mm diameter (approx. 1 minute)

6 Release jig and remove knife

7 Push molten ends of waterstop together

8 Allow to cool (approx. 3 minutes)

9 Release jig and remove waterstop.

10 Inspect welded joint for continuity of weld and correct alignment of profiles. If the weld is unacceptable

repeat operations 1-9.

Useful Tip - Cold Weather Application A small piece of waterstop can

be used to test temperature of blade.

If charring occurs, cut waterstop back and reweld.

Health & Safety ClauseWelding of Flexible P.V.C. can result in the release of Hydrochloric Acid fumes. In confined areas use arespirator or use forced ventilation. Do not inhale the fumes. On open sites these precautions are not usuallyneccesary but care should be taken not to inhale any fumes. The electric welding knife should be properlyearthed before use.

Waterstop - Notes for use

20

A. Floor jointsWaterstops in floor joints are usually of the externaltype where the floor slab is directly supported by theground and blinding concrete, which give support tothe external waterstop enabling it to resist thehydrostatic pressure from above

If the use of internal waterstops is unavoidable, it isessential that the concrete underneath the waterstopis fully compacted.

B. Wall jointsInternally placed waterstops are generally used inwall joints of water retaining structures andExternally placed waterstop in water excludingstructures.

C. Roof jointsExternal waterstops are usually used rather thaninternally placed waterstops to permit easier placingand compaction of concrete.

D. Fixing of waterstops Internal waterstop - wall installationsInternal waterstops in wall installation may lie ineither the horizontal or vertical planes within the wall.

The waterstop should be supported in split-endformwork accurately wrought to match the profile ofthe waterstop. The shutter should hold the waterstopso that half its width is cast into the concrete at thedesigned position and within specified tolerances.Great care should be taken to ensure that thewaterstop does not fold under the weight of placedconcrete. To eliminate foldover particularly in kickerinstallations, the waterstop should be wired toreinforcing steel using tying wire through the tyingpoints. The wire ties should not puncture thewaterstop.

Internal waterstop - floor/roofinstallationsInternal waterstops are not recommended for use infloor or roof installations. However, if their use isunavoidable, the following should be observed.

The waterstop should be supported in formwork asdescribed above but should not be wired, so that itmay be lifted for proper concrete placement andcompaction. The waterstop should not be allowed tofold over under the weight of the concrete.

External waterstop - floor/roofinstallationsThe waterstop should be laid on the blindingconcrete, or shuttering, whichever is appropriate,along the intended line of the joint before the bottomsteel reinforcement is placed. This sets the pattern ofthe bays prior to concreting and allows the site weldsand the overall quality of the installation to bechecked. The stop end boards should then be firmlybedded on the waterstop.

In water excluding structures when Extaseal is usedin the vertical and horizontal wall joints then thewaterstop should be held in place using Schlegelwaterstop fixing nails through the fixing flange.

E. JointingJoints between waterstops and junctions should bewelded as shown on page 17 so that a continouswatertight network is formed.

F. Concrete Placement and CompactionGeneralA waterstop is only as effective as the concrete intowhich it is cast. Concrete does not bond to PVC andthe hold is provided by well-compacted concrete allaround the waterstop. Poor compaction or placementof the concrete may lead to honeycombing withresultant water percolation around the waterstop.

The following points should be observed prior toconcrete placement. Stop end shutters should be carefully blown out toremove any debris. Externally placed waterstops should bethoroughly cleaned out between the sealing ribs. Shutters should be checked for firmness againstthe waterstop to avoid grout seepage. Waterstop ties should be checked to see that theyare firmly fixed. A final check should be made that all waterstopsare correctly placed and that all junctions arecorrectly installed for adjacent pours.

Internal waterstop - wallsVertical InstallationThe waterstop should be supported in split-endformwork accurately wrought to match the profile ofthe waterstop. The shutter should hold the waterstopso that half its width is cast into the concrete at thedesigned position and within specified tolerances.Great care should be taken to ensure that thewaterstop does not fold under the weight of placedconcrete. To eliminate foldover, the waterstop shouldbe wired to reinforcing steel using tying wire throughthe tying points. The wire ties should not puncture thewaterstop or prevent the vibrator being placed tightto the waterstop or the stop end shutter with resultantpoorly compacted concrete in that zone.

Horizontal installationAs with the vertical installation, folding of thewaterstop should be avoided. With heavy concretepours, the flow should be directed towards theshutter. Unless properly secured, the waterstop mayfold over creating a cavity under the waterstop.

The concrete should be carefully placed around thewaterstop. The concrete should be gradually pouredto cover the whole waterstop, then thoroughlyvibrated ensuring that the vibrator does not foul thetying wires preventing it reaching the bottom of theshutter.

Internal waterstop - floor/roofThe edge of the waterstop should be lifted and theconcrete beneath the waterstop placed firmly againstthe stop end shutter. This should then be vibrated togive good compaction with no honeycombing. Afterthis initial stage, the waterstop should be loweredand further concrete placed around the waterstopand vibrated. Care should be taken not to push thewaterstop down when vibrating. Attention should begiven to reverse any natural curling tendency of thewaterstop.

External waterstop - floor/roofThe concrete should be poured against the stop endshutter and well vibrated to ensure compaction abovethe waterstop.

F. Avoidance of damage to the waterstopStorageWaterstops may be stored outside without protectionin the UK in an area where it will not be liable todamage, by site traffic, plant or other site materials.

The waterstop should be well supported so that it isnot distorted or takes a permanent set duringstorage. The manufacturer's recommendations for themethod of support and stacking height should befollowed.

Superstop Self Swelling Waterstop*

DescriptionSCP Superstop has been developed to provide a watertight seal in construction joints, and isparticularly effective when used in box out applications. When water comes into contact withSuperstop the bentonite expands to form a pressure seal which has been successfully tested towithstand a 33 metre head of water without leakage.

UsesSuperstop can be used in pre-cast or in-situ concrete installations and is ideally suited for thefollowing applications: Concrete Cold Joints in below ground walls Construction Joints in Slabs Water Treatment Works Sewage Treatment Works Pre-cast Concrete Panels

ApplicationSuperstop is fixed either by nailing or adhering into a previously formed 12mm x 25mm void (using areusable void former), around the perimeter of the box out and must be confined on all four sides. DualSeal Waterstop can be used as a puddle flange around the pipes. Concrete is then poured into the boxout and compacted. Any water passing through hairline cracks between the different surfaces willcause the Bentonite to swell and form a totally watertight seal.

Swelltite Hydrophilic Self Swelling Waterstop*

Description:SCP Swelltite Hydrophilic Waterstop is manufactured from a neoprene polymer based hydrophiliccompound and high water absorbent resins. Swelltite has been specifically designed for use in sealingconstruction joints between pre-cast concrete units, steel and in-situ concrete. Unlike traditionalwaterstops Swelltite is centrally placed and bonded flat in the joint prior to making the second pour,activated by water Swelltite will swell up to 5 times its volume and seal the passage of water byexerting pressure across the joint.

Uses:Swelltite was primarily developed for use to provide a watertight seal between pre-cast concrete unitssuch as concrete pipes and tunnel segments, however it can be installed into a previously formedrebate for use in in-situ concrete.

Application:Surfaces must be smooth, dry and free of contamination. The surface must be primed with SCP primerP and allowed to dry. Remove the release paper from the Swelltite and press firmly into position onthe primed surface. Joints in Swelltite must be butted tightly for continuity. Where concrete is to beplaced against Swelltite there must be a minimum of 75mm concrete cover.

Dualtite Hydrophilic Expansion Joint Waterstop*

Dualtite PVC/Bentonite Expansion Joint Waterstop

Description:Dualtite Waterstop consists of a PVC profile manufactured from weldable waterstop grade material incorporatingDual Seal Hydrophilic Bentonite Waterstops, which swell in contact with water, to form a totally watertight seal.The lug on either side of the central section, ensures that Dualtite is fully embedded into the adjacent concretesurface, and its unique central core design allows the joint to open up to 50%. When Dual Seal BentoniteWaterstop is installed in Kicker or Construction Joints, it is simply butt joined to the integral Dual Seal Waterstop,in the Dualtite, to create a totally watertight system.

Uses:Dualtite Waterstop should be used in all Expansion Joints, in conjunction with a Fillerboard, when there is arequirement to keep water in or out of concrete structures. These would include Concrete Reservoirs, WaterTreatment Works, Sewage Treatment Works, Canals, Flood Relief Channels and Basements etc.

Application:Dualtite is fixed centrally to the stop end shuttering, prior to the first concrete pour. When the concrete has curedand the stop end is removed, the Expansion Joint Fillerboard is then located in position, within the locator lugs,and the second pour completed. Welding of straight runs of Dualtite is achieved by using an Electric HeatingBlade, and Dualtite Jig. Changes of direction are achieved using Factory-made Junction Pieces and Intersections

Installation:Dualtite Bentonite Expansion Joint Waterstop is simply nailed to the shuttering prior to the first pour.The lugs secure the waterstop to the concrete as in a conventional waterstop, however, the Dual SealBentonite waterstop acts as a secondary barrier. Should water try to track across the joint. Thiscombination provides the reassurance of installing a mechanical sealing system based on the passivevalve and tortuous path systems pioneered by the Cement and Concrete Association during the early1970's, together with the active water swelling sealing systems of the 1990's.

Specifically for use in concrete expansion joints where an active waterstop is required to providemaximum integrity. Dualtite is easy to install and is fully compatible with the SCP range of constructiontype waterstops, it can be easily welded on site thereby providing a cost effective solution andsimplifying transition between construction and expansion joints with a range of prefabricatedjunctions available.

Dual Seal waterstop is used on its own within construction joints, but when fully integrated withinDualtite offers many advantages.

InstallationInspection:

A. General: Examine surfaces specified to receive waterproofing to ensure that they are in a condition acceptable to manufacturers recommendations. Ensure that voids greater than 10mm are filled with grout, and sharp protrusions over 10mm are removed.

B. Do not Install membranes in standing water.C. Ensure that where tapes are used that the surfaces to which they are to be adhered are free from dirt, dust,

snow, ice release oils and other contaminents.D. Horizontal surfaces should be swept clean, particularly the surface of the wall footing.

Preparation:A. Layout: Anticipate conditions prior to start of work. Note termination and penetration positions to

determine methods for ensuring a watertight envelope.B. Fillets: Form fillets with 50mm of Dual Seal Mastic, or Dual Seal Granules at intersections of walls and

footings . Form fillets with mastic at the inside of vertical corners and around penetrations.Installation:

A. Install the Dual Seal Membrane where shown on the drawings and in accordance with the manufacturers recommendations as approved by the Architect and/or Engineer.

Note: In horizontal applications Dual Seal is normally installed with the bentonite face down, however, Dual Seal LG may be installed under a floor with the bentonite side up depending on the weather and site conditions.

Bentonite Side down:A. Dual Seal membrane is laid directly onto blinding prior to the laying of the slab, however if the substrate

consists of soils, sand, gravel or crushed stone ensure that the aggregate does not exceed 12mm, a 1000g polythene sheet should be used so that the bentonite expands against a smooth substrate.

B. Unroll sheet fully and place the membrane over prepared surfaces in such a manner as to ensure minimumhandling.

C. Install membrane with bentonite side down lapping the edges by 50mm. Tape all overlaps using Bitusheet tape and extend the membrane by 300mm at perimeter to allow sufficient overlap with the vertical membrane and mechanically fix at the toe.

D. Fit closely and seal around pipe penetrations as recommended.E. Inspect and repair any damaged material before placing the concrete, by placing a square of membrane over the

damaged area and fully tape in position.Bentonite side up:

A Ensure that substrate is level and compact. Substrate may consist of soils, sand, gravel or crushed stone provided they are 12mm or smaller in diameter. Ensure that temporary cover is provided to the bentonite to prevent premature expansion.

B. Unroll the Dual Seal LG fully and lay the membrane over the prepared surface, C. Install Dual Seal with edges overlapped by a minimum of 50mm. Joints may be stapled every 200mm.D. Extend the Dual Seal Membrane 300mm up or beyond the perimeter slab. This will be used later to tie

in vertical membrane.E. Fit closely around pipe pentrations as recommended.F. Inspect and repair any damaged material before placing the concrete.G. Protect exposed bentonite from moisture by taping at joints and covering with a polythene strip at edges.

Vertical Backfilled Walls:A. Inspection - Confirm that all areas to receive the membrane are suitably prepared.B. Form fillets at vertical wall / horizontal intersections with Dual Seal mastic and seal at vertical inside

corners, under ledges and at penetrations.C. Place the membrane over prepared surfaces where shown on the drawings. Dual Seal is generally installed

vertically to the outside wall, however it can be installed horizontally along the wall. The HDPE (black) side which should always face the installer when it is being fixed, however an exception to this would be if it was being used in blindside concrete when it is fixed to permanent shuttering in which case Dual Seal LG must be used.

D. After unrolling, the Dual Seal should be nailed across the top, mechanically fixing the membrane every 300mm and allowing the sheet to hang down onto the footing. Install 2nd sheet by overlapping onto the first sheet by 50mm. Pull taught and nail through both sheets at the overlap area, followed by Bitusheet tape centred over the overlap joint, to prevent stones and debris entering the joint.

E. Properly treat all penetrations by cutting a seperate section of the membrane to fit snugly around penetrations and bed on a 50mm triangular Dual Seal mastic fillet.

F. Terminate the membrane at top of walls by mechanically fixing at 300mm centres and make certain that the membrane extends to form continuity with the above ground waterproofing details.

SCP Dual Seal Mastic

Description:A trowlable mastic comprising of a special formulation of expandable minerals and elastomeric compoundwhich expands and stiffens in the presence of water to form an impervious barrier to water penetration.

SCP HPS Waterproofing System for damp and difficult conditions.

Description:Bitusheet HPS Waterproofing System consists of SCP's widely used Bitusheet range of Cross Laminatedmembranes, applied in conjunction with SCP's high performance primer. These components have beenspecifically developed to promote a high bond strength between Bitusheet membranes and substrates withdamp or difficult conditions and where performance is required at temperatures down to -100C

Uses:The Bitusheet HPS Waterproofing System is designed for use where unusually low temperatures are evidentand where dampness exists on the substrate. It is ideal for basement applications and previously coveredearth/concrete reservoir roofs which are being renovated.

Winter Conditions:The Bitusheet HPS Waterproofing System can be installed in most conditions and whilst having a wide

temperature tolerance should not be applied when the temperature is 3oC or more below dew point because of

the risk of condensation, or when temperatures exceed 60oC. With decreasing temperature the membranes

will stiffen. This will not cause any significant problems with installation down to the minimum temperature of

5oC. Bitusheet membranes remain functional and flexible to well below -10oC and will remain stable up to a

normal maximum of 60oC. Where severe temperatures down to -30oC are expected Dual Seal membrane

should be used (see Technical Data Sheet No.44)

Application:Ensure that the substrate is clean and free from surface water and sharp protrusions. Apply the primer evenlyby brush or spray, avoiding pooling and over application. Allow to dry before applying the membrane. If theapplication of Bitusheet is delayed more than 4 hours after priming, the surface must be re-primed.

HPS Primer

Description:A pink mobile liquid designed to improve the bond between Bitusheet and Substrates.

Application:All surfaces must be clean and free from loose matter. Primer can be applied by brush or roller, attemperatures to below -100C, providing that the surface is completely dry prior to application of membrane.

Liquid Asphaltic Compound*

ApplicationConstruction techniques should conform to relevant Codes of Practice, Building regulations and BritishStandards.

Surface to which Liquid Asphaltic Compound are to be applied must be clean, dry and frost - free. Anydefects must be made good, projections being removed and voids filled. Brickwork or Blockworkshould be flush pointed and open textured surfaces rendered.

Apply first coat of Liquid Asphaltic Compound at 1.5m2/L, brushing well to ensure complete coverageand to prevent material from pooling or collecting in depressions. Allow to dry thoroughly beforeapplying second coat at 2.5m2/L. Ensure the membrane is fully dry before proceeding.

When used as a DPM in solid floor construction, the membrane should be brought up adjoining verticalsurfaces to marry with DPC. The membrane should be covered with a minimum 50mm floor screed.A weak rendering (12:1 Sand/Cement) or a suitable protection board must be employed to protect themembrane when backfilling. When used for internal tanking, back pressure should be counteracted bybuilding a blockwork or brick skin 18mm from the membrane and the cavity filled with a sand cementmortar.

Notes

Dr ying times may be extended in cold, humid conditions or in areas of poor ventilation.

Particular attention should be paid to areas where services penetrate the membrane, in such areasthe membrane should be reinforced with a reinforcing fabric and third coat of Liquid Asphaltic Compound used to ensure the integrity of the waterproofing.

Triangular fillets should be employed at all changes in direction.

Ancillary ProductsScp offer a range of products suitable for use with Liquid Asphaltic Compound, these include:

Bitusheet HD Protection BoardA tough durable Polymeric protection board to prevent damage to the membrane during backfill.

BITUSHEET XL HD BITUSHEET M.E. BITUSHEET 1000 gauge BITUSHEET 1200 gauge BITUSHEET 500 gauge BITUSHEET XLR BITUSHEET XL PW BITUSHEET - Gas Barrier

MembraneSurface Preparation:All surfaces should be smooth, clean and dry. Loosely adhering material and sharp protrusions should beremoved by mechanical means. Concrete or renders should be allowed to dry before applying Bitusheetmembrane.

Priming:All vertical surfaces should be primed using Bitusheet Primer. Horizontal surfaces do not require priming wherethe membrane is covered with a screed, floor slab etc. Priming should be carried out as follows:(i) Roll can well before use.(ii) Apply at the rate of approximately 7m2/L. Only prime that area which is to be covered with Bitusheet

within the next 4 hours. Allow to dry for at least 1 hour until touch dry. Keep free from dust.(iii) On very porous surfaces, use two coats of primer.

Application:Internal angles must always be provided with an adequate fillet of concrete or SCP Bituflex Fillet, then afterpriming as previously described a 300mm wide reinforcing strip of Bitusheet must be applied with 150mm oneither side of the centre of the fillet.

External angles or corners must be provided with a 25mm x 25mm splay and this covered with a 300mm widestrip of Bitusheet XL applied equidistant from the centre of the splay.

The first strip should of Bitusheet be laid such that the selvedge is placed to accept the edge of the followingstrip, with each subsequent strip laid in the same way. The protection paper should be removed from theselvedge before bonding the overlap joint.

Horizontal membrane should preferably be laid prior to the application of the vertical membrane, adequatelyprotected from damage by a minimum 25mm screed or protection board, with the membrane bonded to thevertical surface at least 200mm above the top of the screed so that the vertical Bitusheet can be overlaid.

If it is not possible to apply the screed over the DPM before the application of the vertical membrane, full andadequate protection must be given to the horizontal membrane to prevent damage.

Vertical membrane - cut off the appropriate length of membrane, then starting at the top of the area to bewaterproofed, peel off at least 200mm of release sheet and bond the Bitusheet firmly to the surface, tucking theend of the material into the appropriate DPC or chase. Gradually peel off the remainder of the release sheetdownwards, at the same time rolling the material against the surface until the bottom of the wall is reached. Atthe base, the vertical membrane must overlap the horizontal membrane by at least 100mm.

All subsequent sheets must overlap the preceeding sheet by 50mm at the edges onto the selvedge strip and by100mm at ends. Overlaps must be thoroughly rolled to ensure adequate bonding.

Backfilling on vertical applications where an abrasive backfill is to be used the Bitusheet membrane shouldbe protected by a concrete outer skin, brick skin or Bitusheet protection board, the latter being held in place bySCP Joint Filler Adhesive.

Precautions:Bitusheet and Bitusheet Primer must not be applied when the surface temperature of the substrate falls below5C.

When a brick-skin is applied to the face of the vertical Bitusheet, care must be taken not to damage themembrane and a gap of 40mm should be left which is filled with sand/cement mortar as work proceeds.

Only sufficient Bitusheet should be laid which can be protected as work proceeds.

When areas of Bitusheet are left exposed for any length of time ensure that all edges are held in place bybattens.
