Preprufe® Pre-applied Waterproofing Membranes are unique multi-layered composite waterproofing sheets made from a thick solar reflective HDPE film, a highly aggressive pressure sensitive adhesive and a weather resistant protective coating that allows freshly poured concrete to fully adhere to the membrane to prevent water tracking. Unlike some conventional membranes that are vulnerable to water penetration at junctions and penetrations, the unique Preprufe® seal with the concrete prevents any entry or migration of moisture around the structure from hydrostatic pressure or ground contamination.

Preprufe® 800PA is a cold-applied, self-adhesive waterproofing membrane, composed of a reinforced cross laminated HDPE film, and a synthetic non-bituminous adhesive. Preprufe 800PA incorporates the Preprufe Advanced Bond Technology™.

Bituthene® 4000/ 4000S is a flexible waterproof membrane combining a high performance cross laminated, HDPE carrier film with a unique super sticky self-adhesive rubber bitumen compound.

Bituthene® 8000/ 8000S combines the proven Bituthene adhesive technology with a unique, grey coloured carrier film to provide superior performance and easier installation. Bituthene 8000/ 8000S is extremely tough but any accidental damage which would otherwise be missed, is made visible by the black compound showing through the light grey film.
