Sodium Bentonite Waterproof Layer
Sodium Bentonite Waterproof Layer, GCL, is a new type of environmentally friendly flexible geosynthetic materials, composed of two layers of geotextile and bentonite and the bentonite is composed of natural sodium bentonite particles and corresponding additives mixed together, with special equipment by cluster method with the uniform pinhole sprint firmly sealing between the polypropylene woven fabric and nonwoven fabric. Natural Sodium Bentonite Waterproof Layer (GCL) is a kind of anti-seepage liner between CCL (compacted thick clay impervious liner) and high polymer geomembrane. For some special environmental engineering needs, such as landfill, and so on, we can also use a HDPE film on the waterproof carpet to play a double-layer better anti-seepage effect.
There are two kinds of bentonite in sodium bentonite waterproof layer, a kind of calcium based bentonite waterproof blanket, fast hydration speed, the maximum ratio of bentonite is about 5 times, the general color is golden yellow. One is the sodium bentonite ore, the hydration rate in 24 hours, expansion ratio is above 24, the color of dark. The swelling property of sodium base soil is obvious and the swelling ratio is big. It is the material for making bentonite waterproof blanket. Calcium based soil is only suitable for additives. It can not be used as main material.
