5.Advantages compared toGCL in Activated Calcium Bentonite:Its material is totally natural , it is environmentally,highly stable water tightness, water retention, caking, durability and self- healing ,it's becoming a new trend of waterproof to use more environmental materials.

6.Material:the only natural sodium bentonite material form underground 250-300m mine ,accompanying with liufangzi coal ,form million years ago by volcanic detritus soil ,these soil including montmorillonite ,that is bentonite

Now market have two main type bentonite ,one is sodium ,the other is calcium which formed the earth's surface.

however the calcium bentonite can turn to artifical sodium bentonite which haven't the permanent waterproofing system.the loss will turn out half years form its setting.This is way we have to select natural sodium bentonite.

7.Certificate:we passed ISO 9001 ,National Research Center of Testing Techniques for building material
