Circular Fabrications

SCP

Prefabricated Waterstop for Circular Tanks When Extaseal waterstop is required to be prefabricated to form a circle the details below can be used as a design 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 be reduced. Where the radial joints are required the number of chords used should be divisable by the number of radial joints. Circle Radius

SCP Advisory Design Service

n

SCP

SCP offer an advisory/design service to specifiers on the use and application for all our Waterproofing Systems. Using the latest AutoCAD Software we can prepare three dimensional drawings for general arrangement and installation. Upon confirmation of details these drawings can then be ‘unfolded’ into template form for fabrication, thereby ensuring accuracy from design through to manufacture in our inspection controlled workshop environment. Our national team of Technical Sales Engineers are available to liaise with site personnel to discuss and advise

For further information please telephone 01582 842802 upon your specific requirements.

PVC Waterstop Jointing Detail

n

SCP

1

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

2

Locate waterstop in jig, with approx. 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 Clause Welding of Flexible P.V.C. can result in the release of Hydrochloric Acid fumes. In confined areas use a respirator or use forced ventilation. Do not inhale the fumes. On open sites these precautions are not usually neccesary but care should be taken not to inhale any fumes. The electric welding knife should be properly earthed before use.

Waterstop - Notes for use

n

SCP

External waterstop - floor/roof installations

Waterstops in floor joints are usually of the external type where the floor slab is directly supported by the ground and blinding concrete, which give support to the external waterstop enabling it to resist the hydrostatic pressure from above

The waterstop should be laid on the blinding concrete, or shuttering, whichever is appropriate, along the intended line of the joint before the bottom steel reinforcement is placed. This sets the pattern of the bays prior to concreting and allows the site welds and the overall quality of the installation to be checked. The stop end boards should then be firmly bedded on the waterstop.

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

B. Wall joints Internally placed waterstops are generally used in wall joints of water retaining structures and Externally placed waterstop in water excluding structures.

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

C. Roof joints

E. Jointing

External waterstops are usually used rather than internally placed waterstops to permit easier placing and compaction of concrete.

Joints between waterstops and junctions should be welded as shown on page 17 so that a continous watertight network is formed.

D. Fixing of waterstops Internal waterstop - wall installations

F. Concrete Placement and Compaction General A waterstop is only as effective as the concrete into which it is cast. Concrete does not bond to PVC and the ‘hold’ is provided by well-compacted concrete all around the waterstop. Poor compaction or placement of the concrete may lead to honeycombing with resultant water percolation around the waterstop.

Internal waterstops in wall installation may lie in either the horizontal or vertical planes within the wall. The waterstop should be supported in split-end formwork accurately wrought to match the profile of the waterstop. The shutter should hold the waterstop so that half its width is cast into the concrete at the designed position and within specified tolerances. Great care should be taken to ensure that the waterstop does not fold under the weight of placed concrete. To eliminate foldover particularly in kicker installations, the waterstop should be wired to reinforcing steel using tying wire through the tying points. The wire ties should not puncture the waterstop.

The following points should be observed prior to concrete placement. ■ Stop end shutters should be carefully blown out to remove any debris. ■ Externally placed waterstops should be thoroughly cleaned out between the sealing ribs. ■ Shutters should be checked for firmness against the waterstop to avoid grout seepage. ■ Waterstop ties should be checked to see that they are firmly fixed. ■ A final check should be made that all waterstops are correctly placed and that all junctions are correctly installed for adjacent pours.

Internal waterstop - floor/roof installations Internal waterstops are not recommended for use in floor or roof installations. However, if their use is unavoidable, the following should be observed. The waterstop should be supported in formwork as described above but should not be wired, so that it may be lifted for proper concrete placement and compaction. The waterstop should not be allowed to fold over under the weight of the concrete.

20

Internal waterstop - walls Vertical Installation

F. Avoidance of damage to the waterstop Storage

The waterstop should be supported in split-end formwork accurately wrought to match the profile of the waterstop. The shutter should hold the waterstop so that half its width is cast into the concrete at the designed position and within specified tolerances. Great care should be taken to ensure that the waterstop does not fold under the weight of placed concrete. To eliminate foldover, the waterstop should be wired to reinforcing steel using tying wire through the tying points. The wire ties should not puncture the waterstop or prevent the vibrator being placed tight to the waterstop or the stop end shutter with resultant poorly compacted concrete in that zone.

Waterstops may be stored outside without protection in the UK in an area where it will not be liable to damage, by site traffic, plant or other site materials. The waterstop should be well supported so that it is not distorted or takes a permanent set during storage. The manufacturer's recommendations for the method of support and stacking height should be followed.

Installation When fixing to formwork the contractor should not puncture, cut or tear the waterstop to suit reinforcement. Waterstops are particularly vulnerable to damage when one half is bedded in concrete and the other half is exposed. Care should be taken to avoid damage by plant, site traffic etc.

Horizontal installation As with the vertical installation, folding of the waterstop should be avoided. With heavy concrete pours, the flow should be directed towards the shutter. Unless properly secured, the waterstop may fold over creating a cavity under the waterstop.

Specification Compliance SCP P.V.C. waterstops are manufactured from high quality polyvinylchloride resins and plasticisers. Tensile Strength: 13.8 N/mm2 (2000 p.s.i.). Elongation at break: 300% (nominal) B.S. Softness (B.S.2571/1955). 45 at 20˚C. Relative density: 1.30. SCP P.V.C. waterstops comply with the requirements of B.S. 2571 and B.S. 2782. Schlegel P.V.C. waterstops conform to the recommendations of the American Concrete Institute when tested to the relevant ASTM specifications (D-792, D-412, D-624 and D-746). The material specification meets the requirements of Section 2.83 of the Civil Engineering Specification of the Water Industry Issued by the National Water Council. SCP P.V.C. waterstops comply with U.S. Corps of Engineers Specification CRD-C 572-74. SCP P.V.C. waterstops are accepted for use by National Water Council (Document No. 4-31-02/June 1985). U.K. Water Fittings Byelaws Scheme Listed.

The concrete should be carefully placed around the waterstop. The concrete should be gradually poured to cover the whole waterstop, then thoroughly vibrated ensuring that the vibrator does not foul the tying wires preventing it reaching the bottom of the shutter.

Internal waterstop - floor/roof The edge of the waterstop should be lifted and the concrete beneath the waterstop placed firmly against the stop end shutter. This should then be vibrated to give good compaction with no honeycombing. After this initial stage, the waterstop should be lowered and further concrete placed around the waterstop and vibrated. Care should be taken not to push the waterstop down when vibrating. Attention should be given to reverse any natural curling tendency of the waterstop.

External waterstop - floor/roof The concrete should be poured against the stop end shutter and well vibrated to ensure compaction above the waterstop.

Superstop Self Swelling Waterstop

n

SCP

Description SCP Superstop has been developed to provide a watertight seal in construction joints, and is particularly effective when used in ‘box out’ applications. When water comes into contact with Superstop the bentonite expands to form a pressure seal which has been successfully tested to withstand a 33 metre head of water without leakage.

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

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

Swelltite Hydrophilic Self Swelling Waterstop

n

SCP

Description: SCP Swelltite Hydrophilic Waterstop is manufactured from a neoprene polymer based hydrophilic compound and high water absorbent resins. Swelltite has been specifically designed for use in sealing construction joints between pre-cast concrete units, steel and in-situ concrete. Unlike traditional waterstops 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 it’s volume and seal the passage of water by exerting pressure across the joint. Uses: Swelltite was primarily developed for use to provide a watertight seal between pre-cast concrete units such as concrete pipes and tunnel segments, however it can be installed into a previously formed rebate for use in in-situ concrete. Application: Surfaces must be smooth, dry and free of contamination. The surface must be primed with SCP primer ‘P’ and allowed to dry. Remove the release paper from the Swelltite and press firmly into position on the primed surface. Joints in Swelltite must be butted tightly for continuity. Where concrete is to be placed against Swelltite there must be a minimum of 75mm concrete cover. SCP Swelltite

Dualtite Hydrophilic Expansion Joint Waterstop

n

SCP

Dualtite PVC/Bentonite Expansion Joint Waterstop Description: Dualtite Waterstop consists of a PVC profile manufactured from weldable waterstop grade material incorporating Dual 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 concrete surface, and its unique central core design allows the joint to open up to 50%. When Dual Seal Bentonite Waterstop 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 a requirement to keep water in or out of concrete structures. These would include Concrete Reservoirs, Water Treatment 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 cured and 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 Heating Blade, and Dualtite Jig. Changes of direction are achieved using Factory-made Junction Pieces and Intersections

SCP

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 Seal Bentonite waterstop acts as a secondary barrier. Should water try to track across the joint. This combination provides the reassurance of installing a mechanical sealing system based on the passive valve and tortuous path systems pioneered by the Cement and Concrete Association during the early 1970'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 provide maximum integrity. Dualtite is easy to install and is fully compatible with the SCP range of construction type waterstops, it can be easily welded on site thereby providing a cost effective solution and simplifying transition between construction and expansion joints with a range of prefabricated junctions available. Dual Seal waterstop is used on it’s own within construction joints, but when fully integrated within Dualtite offers many advantages. Typical Applications:

Installation Inspection: A.

B. C. D.

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. Do not Install membranes in standing water. 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. Horizontal surfaces should be swept clean, particularly the surface of the wall footing.

Preparation: A. B.

Layout: Anticipate conditions prior to start of work. Note termination and penetration positions to determine methods for ensuring a watertight envelope. 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 manufacturer’s 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.

B. C.

D. E.

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. Unroll sheet fully and place the membrane over prepared surfaces in such a manner as to ensure minimum handling. 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. Fit closely and seal around pipe penetrations as recommended. 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

B. C. D. E. F. G.

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. Unroll the Dual Seal LG fully and lay the membrane over the prepared surface, Install Dual Seal with edges overlapped by a minimum of 50mm. Joints may be stapled every 200mm. Extend the Dual Seal Membrane 300mm up or beyond the perimeter slab. This will be used later to tie in vertical membrane. Fit closely around pipe pentrations as recommended. Inspect and repair any damaged material before placing the concrete. Protect exposed bentonite from moisture by taping at joints and covering with a polythene strip at edges.

Vertical Backfilled Walls: A. B. C.

D.

E. F.

Inspection - Confirm that all areas to receive the membrane are suitably prepared. Form fillets at vertical wall / horizontal intersections with Dual Seal mastic and seal at vertical inside corners, under ledges and at penetrations. 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. 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. 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. 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. 41

SCP

SCP HPS Waterproofing System for damp and difficult conditions. Description: Bitusheet HPS Waterproofing System consists of SCP's widely used Bitusheet range of Cross Laminated membranes, applied in conjunction with SCP's high performance primer. These components have been specifically developed to promote a high bond strength between Bitusheet membranes and substrates with damp 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 evident and where dampness exists on the substrate. It is ideal for basement applications and previously covered earth/concrete reservoir roofs which are being renovated. Bitusheet XL on Bitusheet HPS Primer

Extaseal Waterstop Bitusheet XL

SCP Protection Board

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 evenly by brush or spray, avoiding pooling and over application. Allow to dry before applying the membrane. If the application 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, at temperatures to below -100C, providing that the surface is completely dry prior to application of membrane.

Application Construction techniques should conform to relevant Codes of Practice, Building regulations and British Standards. Surface to which Liquid Asphaltic Compound are to be applied must be clean, dry and frost - free. Any defects must be made good, projections being removed and voids filled. Brickwork or Blockwork should be flush pointed and open textured surfaces rendered. Apply first coat of Liquid Asphaltic Compound at 1.5m2/L, brushing well to ensure complete coverage and to prevent material from pooling or collecting in depressions. Allow to dry thoroughly before applying 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 vertical surfaces 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 the membrane when backfilling. When used for internal tanking, back pressure should be counteracted by building a blockwork or brick skin 18mm from the membrane and the cavity filled with a sand cement mortar. 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 areas the 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 Products Scp offer a range of products suitable for use with Liquid Asphaltic Compound, these include: Bitusheet HD Protection Board A tough durable Polymeric protection board to prevent damage to the membrane during backfill. Walldrain An HDPE cavity drain used to protect the membrane and to remove build up of water pressure. Bitusheet Reinforcing strip Used to reinforce corners and change in direction. Bitusheet Double Sided Bituminous Tape Used for adhering the protection board or Walldrain to the membrane.

BITUSHEET M.E. BITUSHEET 1200 gauge BITUSHEET XLR BITUSHEET - Gas Barrier Membrane

Surface Preparation: All surfaces should be smooth, clean and dry. Loosely adhering material and sharp protrusions should be removed by mechanical means. Concrete or renders should be allowed to dry before applying Bitusheet membrane.

Priming: All vertical surfaces should be primed using Bitusheet Primer. Horizontal surfaces do not require priming where the 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 after priming as previously described a 300mm wide reinforcing strip of Bitusheet must be applied with 150mm on either 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 wide strip 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 following strip, with each subsequent strip laid in the same way. The protection paper should be removed from the selvedge before bonding the overlap joint. Horizontal membrane should preferably be laid prior to the application of the vertical membrane, adequately protected from damage by a minimum 25mm screed or protection board, with the membrane bonded to the vertical 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 and adequate 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 be waterproofed, peel off at least 200mm of release sheet and bond the Bitusheet firmly to the surface, tucking the end of the material into the appropriate DPC or chase. Gradually peel off the remainder of the release sheet downwards, at the same time rolling the material against the surface until the bottom of the wall is reached. At the 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 by 100mm 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 should be protected by a concrete outer skin, brick skin or Bitusheet protection board, the latter being held in place by SCP Joint Filler Adhesive.

Precautions: Bitusheet and Bitusheet Primer must not be applied when the surface temperature of the substrate falls below 5°C. When a brick-skin is applied to the face of the vertical Bitusheet, care must be taken not to damage the membrane 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 by battens.

DESCRIPTION: SCP Slabdrain is a cavity drain former manufactured from a dimpled H.D.P.E., designed to provide a drainage channel beneath the concrete in floor and wall construction. The former is provided with selvedges to enable joints to be sealed to give a water and gas tight membrane.

USES: Generally in type C construction to provide grade 4 protection as defined in BS 8102: 1990. “Protection of structures against water from the ground”. SCP Slabdrain may be used in floors and walls to provide a drainage void beneath the concrete to relieve both water and gas pressures. The HDPE core provides high strength to resist the loads imposed by placing wet concrete. By sealing the selvedge joints, SCP Slabdrain will also provide the membrane.

BENEFITS: • Combined former and membrane. • Provides a high water flow rate. • Easily applied. • Selvedge side laps. • High load resistance. • Lightweight.

INSTALLATION: GENERAL SCP Slabdrain is applied dimple side down to the substrate, the surface should be smooth and even. Subsequent rolls should be laid so that the selvedges overlap, end laps are formed by overlapping a minimum of 200mm (3 dimples) and interlocking the dimples. Selvedges are sealed using 50mm Double Sided Tape, end laps are sealed with Uraflex Sealant. SCP Slabdrain is fixed to the substrate using Bitusheet 75mm Double Sided Tape applied onto Bitusheet Primer. Alternatively SCP Slabdrain may be mechanically fixed through the base of the dimples and sealing all fixings End lap sealed with Uraflex Sealant

SCP

SCP Slabdrain should be terminated at the wall and sealed to it with a 300mm strip of Bitusheet tape lapping 150mm onto the Slabdrain and 150mm up the wall. The dimples should be filled with fast setting grout to provide a flat surface to receive the membrane. Once dry all surfaces should be primed with Bitusheet Primer, and allowed to dry, then the Bitusheet strip applied. The same technique is to be adopted at columns or other abutments. Where a drained wall is also required, the SCP Slabdrain is turned up the wall a minimum of 200mm and interlocked over the vertical application by a minimum of 3 dimples. All laps to be sealed as previously described. Ensure the drain cavity is maintained at the wall/floor junction.

DRAINAGE CHANNELS. SCP Slabdrain should be carried through to all drainage channels and sumps as directed by the Engineer. FOLLOWING TRADES No heavy plant or wheel barrows should be used directly on the slabdrain, walkways must be provided for wheel barrows etc. Repairs may be effected by cutting and placing a piece of Slabdrain over the affected area, overlapping and sealing as previously described. Steel mesh reinforcement, if required, can be supported off the Slabdrain in the usual manner.

SCP Walldrain consists of a preformed lightweight plastic core bonded to a geotextile filter.The filter was specially developed to permit free entry of water, but not soil, and so prevent soil particles from clogging the drainage system. Walldrain is designed to be placed with the geotextile filter layer facing the direction of water seepage or backfill. Walldrain can be applied against waterproofing membranes or directly against the masonry/concrete substrate.

Uses Walldrain relieves hydrostatic pressure against the vertical walls of buried structures - basements, retaining walls, reservoirs, tunnels, bridge abutments, culverts and underground car parks. Walldrain provides a second line of defence to channel seepage water away from the structure and is designed to fully comply with the requirement of type 'C' design BS 8102.

DPC/Cavity Tray Joint Support System

n

SCP

Description The SCP Joint Support System comprises of a unique (patent pending) composition of flexible plastic, sealed with a pre-bonded self adhesive strip and adjustable locking support. The unique locking support allows the joint system to cater for varying cavity widths and provides rigidity where longitudinal joints need to be made at critical points within cavities. The SCP Joint Support System combines flexibility of use with joint integrity and fully complies with the current standards laid down for the use and application of cavity trays.

Preparation No preparation is required for installing the joint support where cavity tray’s are to be built-in to internal brick or blockwork. Where cavity trays are to be surface fixed a 100mm band of bituminous primer should be applied to the substrate prior to application of a 100mm wide double sided tape to allow continuity of the cavity tray either side of the joint support.

Application Once the surface to which the cavity tray is to be fixed, has been suitably prepared the joint support is simply installed either by building-in to the inner and outer leaves of brick/blockwork, or surface fixed as described above. The linear run of cavity tray is bonded onto the joint support by removing the release paper on the integral bituminous strip provided. The joint is then completed by applying a 100mm wide of bituminous tape (supplied) which is then sandwiched between both runs of cavity tray. The joint support is also used to fully bond between linear run and preformed junctions.

Supply The SCP Joint Support System is supplied in boxes of 10 complete with one roll of 100mm wide double sided bituminous tape. For surface fixing applications a plastic fixing strip is available and supplied separately in 2 metre lengths. Joint Support

Two Part Sealants. Joint Design and Application

n

SCP

Joint Design: Elastomeric Sealant. ‘4254’Two Part Polysulphide, Non Biodegradeable Polysulphide, Coldseal 200-90, Coldseal 200D. The optimum width to depth ratio should be 2 : 1 with a minimum depth of 10mm. As shown below Butt Joints up to

20mm Wide 21 – 25mm Wide 26 – 30mm Wide 31 – 40mm Wide

= = = =

10mm Deep 13mm Deep 15mm Deep 20mm Deep

A bond breaker strip must be placed at the back of all expansion and contraction joints prior to placing the sealant. Where bitumen impregnated filler boards are used care must be taken to ensure that bitumen does not come into contact with the sealant.

Mixing and Application: Add the entire contents of Pack B to Pack A and stir for a full five minutes, preferably using a slow speed electric drill with blade type stirrer, until a completely homogeneous mix is obtained. Take care to avoid including excess air. Mixing is made easier if the Pack B is added and mixed in two stages. Immediately after the sealant is mixed it should be applied to the primed joint. Use of masking tape will help to obtain a clean finish.

Preparation of substrate: All joints should be completely dry and free from all traces of dirt, dust, grease, any previous sealants, and other foreign matter. Cleaning may be carried out by wire brushing, either hand or machine operated, grit blasting or grinding. In all cases, a clean bonding surface must be obtained. Joint sides must be parallel and straight. Spalled joints should be repaired with an appropriate material, such as Epoxy mortar. Following preparation, place into the base of the joint a bond breaker or back up material to form the correct cross section for joint sealant and to prevent the sealant bonding to the base of the joint.

Priming: The sides of the prepared joint should be primed with the appropriate primer; for porous surfaces e.g. concrete, wood, nosings etc. - use Primer P. For non-porous surfaces e.g. steel, glass etc. - use Primer N. After priming, allow half an hour for solvents to evaporate. If application of the sealant is delayed for more than two hours after priming, joints should be re-primed. For all epoxy nosings, Schlegel Primer P must be used.

Cure Times: The application time and rate of cure will depend upon the temperature of sealant and the ambient temperature at the time of application. At higher temperatures, the rate of cure will be faster. Do not apply at temperatures below 4°C.

Cleaning of Tools: Tools should be cleaned with Cleaning Solvent before the sealant cures.

Health & Safety Precautions: Harmful if taken internally, do not inhale the fumes. Primer N is highly flammable with a flash point of not below 10°C. Primer P is flammable with a flash point of not below 40°C. Avoid inhaling the fumes of these primers.

Storage: The storage shelf life is approximately 12 months, but the material should be used before the date stamped on the container. Storage temperature range is 5°C to 28°C. Store in dry conditions.

Description: Primer type ‘P’ is a blend of moisture curing urethane and hydrocarbon solvents forming a clear, brush applied liquid.

Uses: Primer type ‘P’ is used, following joint preparation, to seal porous Joint void surfaces prior to the installation of ‘4254’ Two Part Polysulphide, Coldseal 200D or Coldseal 200/90 joint sealants.

Application: Primer should not be applied at temperatures below 5°C. A bond breaker strip must be placed at the back of all expansion and contraction joints prior to placing the sealant. Where bitumen impregnated filler boards are used care must be taken to ensure that bitumen does not come into contact with the primer or sealant. All joints should be completely dry and free from all traces of dirt, dust, grease, any previous sealants, and other foreign matter. Cleaning may be carried out by wire brushing, either hand or machine operated, grit blasting or grinding. In all cases, a clean bonding surface must be obtained. Joint sides must be parallel and straight. Spalled joints should be repaired with an appropriate material, such as Epoxy mortar. Following preparation, place a bond breaker or back up material into the bottom of the joint void to form the correct cross section for joint sealant and to prevent the sealant bonding to the base of the joint. A thin coating of Primer type ‘P’ should be brushed onto the sides of the prepared joint. After priming, allow 30 to 60 minutes for solvents to evaporate and the primer to become touch dry before applying the sealant. If application of the sealant is delayed for more than two hours after priming the joints should be re-primed.

Coverage: Nominal coverage 6-8 m2 per litre. 20mm x 20mm joint 1 litre per 150 linear metres of joint

Packing: 1 Litre can 5 Litre can

Hazard Data: Flammable liquid, flash point 48°C. Store away from heat and out of direct sunlight. Avoid breathing vapour. Wear eye protection. Avoid skin contact. In case of eye contact rinse with water for at least 15 minutes and seek medical attention.
