Bithuthene GP

Bituthene® GP is a combination of a high-density polyethylene film and a self-adhesive rubber/ bitumen compound. It is supplied in rolls 1 mm thick overall, 1m wide and 25m long (25 m2).

The product is for low-risk applications only and is capable of resisting a hydrostatic head up to 1m. All concrete and masonry surfaces to which the membrane is to be applied must have a smooth finish. Surfaces should be clean, dry, free of voids and any sharp protrusions. Masonry surfaces must be rendered to provide an even flush surface, if not rendered then all brick or blockwork must be flush pointed. For higher risk applications, we would recommend the use of Bituthene® 4000, Bituthene® 8000 or Preprufe® 800PA
