PREFLEX 3000 is a pre-applied HDPE, fully bonded waterproofing membrane. PREFLEX 3000 is supplied with a self-adhesive selvedge along one side of the roll to provide sealed laps. It consists of a multi-layer composite, including high-density PE film, a polymer layer, and a unique proprietary layer, which allows poured concrete to bond fully with the membrane, providing an excellent barrier against water passage between the waterproofing membrane and the structure.
