Preprufe 250 waterproofing membranes bonding with poured concrete mix for foundation slabs and single-sided formwork walls for underground parts of buildings.<\/p>\n
Preprufe 250 is a composite, sheet membrane, consisting of an HDPE carrier layer, an active adhesive layer and a layer resistant to weather conditions.
\nUtilizing the unique GCP Advanced Bond Technology\u2122, Preprfe 250 creates a continuous and permanent bond with the concrete to prevent water migration and provide long-term durability waterproofing protection.<\/p>\n
The Preprufe 250 system includes:<\/strong> Preprufe 250 is placed horizontally on suitably prepared lean concrete and vertically on one-sided stay-in-place formwork. The concrete mix is placed directly on the active side of the membrane. The specially developed active adhesive layer of the Preprufe membrane creates a continuous and integral seal of the poured concrete mix. The Preprufe 250 membrane is intended for use in reinforced concrete structures, concreted on site.<\/p>\n Product advantages:<\/strong> Preprufe 250 waterproofing membranes bonding with poured concrete mix for foundation slabs and single-sided formwork walls for underground parts of buildings.
