RAWMAT® HDB » Type SF Range
For below-ground structures, used for the protection of underground structures in areas of fluctuating ground water tables.
The SF1 series of membranes are produced in rolls of 1m width, 5m long, and can be handled manually.
The SF2 series of membranes are produced in rolls of 2m width, 50m long, and lend themselves to swifter coverage.
Type SF gives additional protection to the clay core in the Structural Waterproofing sector, where fluctuating water tables may be present.
The RAWMAT® Type SF material consists of a UV-stabilised non-woven needle-punched 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, the non-woven geotextile layer prevents migration of the bentonite from within the composite.

A factory pre-hydrated sodium bentonite membrane for the waterproofing of below ground structures in accordance with BS8102 : 1990 which is used for the protection of underground structures in areas of fluctuating ground water tables, typically used in Structural Waterproofing applications.
