CLEARANCE - Fosroc Supercast SW10 (5mmx20mmx15m)

2437040
FOS8094

Fosroc Supercast SW are swellable waterstops made from high performance synthetic elastomer strips for in-situ concrete, which have a delayed swell action which helps prevent pre-swell during wet site conditions. Expansion of the waterstop creates a positive pressure against the faces of the concrete joint, thus preventing water passing through the joint

  • Suitable for use in contact with potable water and are Water Regulations Advisory Scheme approved products
  • Supercast SW20 has a larger section and so offers a greater surface area of contact to the concrete in areas of higher risk, such as when waterproofing Grade 3 basements.

The Supercast SW range consists of swellable waterstops; Supercast SW formed sections (SW10 & SW20), Supercast SWX gun-applied paste and Supercast SW Adhesive.

Description

Supercast SW should be used to prevent the passage of water through non-movement joints in both new in-situ concrete and between new and existing concrete. Supercast SW increases in volume up to a maximum of 200% and gives resistance to hydraulic pressure.

Swelling of Supercast SW in fresh concrete is minimal therefore maximising the positive pressure seal provided by the hydrophilic to the protected joint.

Supercast SW20 has a larger section and so offers a greater surface area of contact to the concrete in areas of higher risk, such as when waterproofing Grade 3 basements. Both Supercast SW10 and SW20 have a delayed swell action which helps prevent pre-swell during wet site conditions.

Uses

  • Integral sealing for construction joints in concrete cast in-situ
  • Convenient and problem solving in situations where a conventional waterstop would require complex shuttering
  • Typical uses include secant piled and diaphragm walled basements, pile caps and casting against old concrete
  • Can provide simple solutions to detailing pipe entries, construction joints in the vertical plane and to kicker joints



Application Notes


  • Supercast SW may be fixed with Supercast SW Adhesive on smooth surfaces, but Supercast SWX Adhesive should be used where concrete is rough
  • The adhesive bed may be supplemented with occasional suitable small headed nails if required
  • Where joints are needed in the waterstop application a butt joint should be formed. An overlap or sidelap joint is not recommended
  • Allow the adhesive to cure for at least 8 hours prior to placing concrete during which it should not be subjected to immersion. Excessive delays between waterstop installation and concrete placement should be avoided
  • For applications in conjunction with Supercast Watertight Concrete construction Supercast SW20 should be placed into a 20mm wide x 5mm deep rebate and bonded with a continuous 12 - 15mm bead of Supercast SWX
  • SW10 supplied in 5 mm x 20 mm x 15 metre rolls. SW20 supplied in 10 mm x 20 mm x 5 metre rolls
  • Coverage: usually single run of strip per joint



Limitations


  • While Supercast SW20 is an BBA approved product, Supercast SW10 is not BBA approved
  • Should not be used for expansion joints or those subject to movements in excess of 2mm
  • Swell rate is dependent on the quality (solids content) of water and the temperature of water. The lower the temperature and the greater the solids content, the lower the swell rate
  • Should not be used in locations which allow free unrestrained swelling or for free standing walls, such as bund or dwarf walls, where the swell pressure is sufficient to lift the wall from its foundations
  • Must not be immersed in water prior to concrete placement, however, Supercast SW20 can tolerate up to 2 day’s exposure to damp conditions on site
  • There are no known health hazards associated with Supercast SW10 and SW20 in normal use
