Type S Range membrane for below-ground structures

The S1 series of membranes are produced in rolls of 1m width, 5m long, and can be handled manually.

The S2 series of membranes are produced in rolls of 2m width, 50m long, and lend themselves to swifter coverage.

Type S materials are mainly used in Structural Waterproofing applications.

The RAWMAT® HDB Type S material consists of a UV-stabilised woven geotextile layer, a factory pre-hydrated natural sodium bentonite central core and a non-woven perforated scrim layer. The scrim allows intimate contact between the bentonite core and the concrete to which it is applied.

RAWMAT® HDB Type S is laid with the perforated scrim in contact with the prepared substrate, and the woven geotextile uppermost.
