Preprufe 200 is a composite sheet membrane comprised of a robust HDPE film, an aggressive pressure-sensitive adhesive and a weather resistant coating. Using patented Advanced Bond Technology, Preprufe 200 Membrane provides a continuous seal that resists water ingress and migration between the membrane and the structure. Once concrete has been cast, Preprufe 200 forms a continuous and integral seal to the poured concrete. It can be applied either horizontally to smooth prepared concrete, well-rolled and compacted sand or compacted crushed stone blinding; or vertically to permanent formwork or adjoining structures.

Preprufe 200 Membrane: Robust membrane for horizontal use below concrete slabs or vertically against soil retention systems.
