GCL Sodium Bentonite Waterproof Blanket

                                           GCL Sodium Bentonite Waterproof Blanket 

    Since sodium bentonite can expand 10-30 times of its size after absorbing water because of its high expansibility, so we use it as the middle layer and stitched with non woven fabric on both sides to get a kind of gel structure water-proof material.

    It is convenient for construction，even can be used in minus 30 degree centigrade. There is no doubt that it is new type non-toxic, environmental protection, waterproof and anti-seepage engineering blanket of natural inorganic material making.
