Besamembran is a three-layer composite polymer membrane consisting of a robust polymer layer laminated on one side with a polyester fleece, designed to bond permanently to concrete cast against it.
The system seals external or internal non-deformable concrete substrates, horizontal and vertical, and covers floor slabs, walls, vaults, civil engineering elements including tunnels, and parts thereof.
The system is completed by ancillary materials: APP40H double-sided adhesive tape, APP150 tape, APP10/7 sealing cord, EPDM flanges for pipes and round penetrations, and a liquid sealant based on a bitumen-rubber or butyl compound.
