HYDRAULIC PRESSURE-RESISTANT WATERPROOF MATERIAL FOR CONSTRUCTS

摘要

PURPOSE: A hydraulic pressure resistant waterproof material for a construction structure is provided to improve waterproof properties without increasing the thickness of the waterproof material by including super absorbent polymer. CONSTITUTION: A hydraulic pressure resistant waterproof material for a construction structure comprises twofold non-woven fabrics, bentonite and/or super absorbent polymer. The twofold non-woven fabrics are welded by needle punching. The bentonite and/or super absorbent polymer are formed between the twofold non-woven fabrics.
