RAWMAT HDB SLABSEAL
Prefabricated bituminous membrane
RAWMAT HDB® SLABSEAL 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 SLABSEAL version needs to be combined with a permeable film (maximum bentonite gel permeation) and HDPE. This provides maximum safety in horizontal structures with large exposed surfaces as well as in rainy and windy climates.
