Product Introduction
Bentonite for Waterproof
Product Useage
This product has a property of swelling in water and the swelling index can reach from 15 to 20.
What's more, the highdensity colloids formed after expanding. have exclusive performance of
water. Due to this property , natural sodium bentonite can be used as waterproof material in
many fields.
Product Use
waterproof property of natural sodium bentonite is mainly embodied in three fields. To be more
specific, it has an antiseepage effect in the field of construction engineering municipal engineering,
subway, garden, artificial lake) and has antiseepage effect as well as corrosion resistant effect i
n the field of environmental sanitation. Besides, it also has an antiseepage effect in the field of
