Product Information

The mineralogical name of bentonite is montmorillonite. Natural bentonite can be divided into two types: sodium group and calcium group. Bentonite has the characteristic of swelling when encountering water. Generally, when calcium-based bentonite expands, its volume after expansion is only about three times of its own volume. When sodium-based bentonite encounters water, it absorbs five times of its own weight of water and its volume after expanding is 15-17 times of the original volume. It has a certain overall shear strength.

Product Features

1. Its performance price ratio is high. Its uses is very extensive. The width of product can reach 6 meters, which greatly improves the construction efficiency.

2. The products are applicable to municipal (landfill), water conservancy, environmental protection, artificial lakes and underground waterproofing and seepage prevention works of buildings.

3. It can still be constructed under negative temperature (-20), it can also be constructed on damp base (but not bright water);but it can not be constructed under rain or snow.

4. Because bentonite is inorganic material, its durability is more better than organic waterproof material.
