RAWMAT HDB®-S is an active waterproof membrane based on high-density pre-hydrated bentonite. Its special patented pre-gel technology provides appropriate expansion regardless of the composition of groundwater. The HDB-S version needs to be combined with a permeable film (maximum bentonite gel permeation) and a polypropylene woven geotextile. This provides maximum security when placing retaining walls.
