Sealing Membrane Preprufe 300R PLUS/Preprufe 160R PLUS

Durable HDPE membrane for water and radon-proof construction. When casting, a self-adhesive bond is formed with the concrete. This prevents the water from penetrating between the membrane and the concrete. Preprufe PLUS is different from Preprufe STANDARD, because it is a “kick-out roll." The overlap has better adhesive properties, and can handle installation at 0 °C without additional tape. Preprufe 160 is used for concrete slabs up to 350 mm.
