Grace Preprufe 300R & 160R

Preprufe 300R and 160R membranes are unique composite sheets comprising a thick HDPE film, an aggressive pressure sensitive adhesive and weather resistant protective coating. The unique Preprufe membranes bond to concrete prevents ingress or migration of water around the structure.

Preprufe 300R is a heavy duty grade for use below slabs and on rafts (i.e mud slabs).
Designed to accept the placing of heavy reinforcement using conventional concrete spacers.

Preprufe 160R is a thinner grade for blindside, zero property line applications against soil retention systems.
