Application

  • Tanking, planters and temporary protection (internal and external).
  • Road and railway construction, bridges and tunnels, and reservoirs.
  • For basements and subterranean structures.
  • Protection layer for concrete pour. Suitable for use as a horizontal vapour barrier and damp-proof layer, covered with a concrete screed.

Description

Heavy duty protection and drainage layer.


Features and benefits:

  • High density polyethylene (HPDE).
  • Designed for areas requiring greater compression tolerance, impact resistance and larger volume of water drainage.
  • Waterproof membrane manufactured with an egg-box shaped profile to prevent abrasion and puncturing of tanking membranes and allow water to drain vertically down the side of the structure.
  • Resistant to chemicals, roots, mould and bacteria, but requires protection from UV.
  • Harmless to drinking water.

Fixing

Wall fixing.

  • Fix battens to the wall and secure the sheet with pins and studs.
  • The studs are specially designed to fit into the cups. They have a hole in the middle to drive the nails or screws through and will seal the membrane around the nail fixing so no water will go into the pierced area.
  • A cover profile can be fitted to the top edge of the drain, ensuring ventilation of the air gap and prevents particles or water clogging the cavity.


Accessories

Not required.

Protecto-drain tape.

Bituminous double sided tape for bonding sheets together and to the structure.
