RAWMAT HDB P
Prefabricated bituminous membrane
RAWMAT HDB®-P 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-P version needs to be combined with a strong non-woven geotextile. This provides maximum adhesion even when installing on uneven substrates such as earth and piling.
