Products Description

Bentonite Composite Waterproof Blanket is a special geosynthetic material used in artificial lakes and water features, landfills, underground garages, roof gardens, pools, oil depots and chemical dumps, etc. It is made of high expansion of sodium bentonite filled in a special composite geotextile and non-woven fabric between the needle-punching method into the bentonite impermeable mat can form many small fiber space, is the bentonite particles can not flow like a direction. When water is encountered, a uniform high-density gel-like waterproof layer is formed in the mat, effectively preventing water leakage.

Features: 1, It has excellent waterproof and impermeable properties, impermeable hydrostatic pressure up to 1.0MPa or more, permeability 5 × 10-11cm / s, unit area bentonite quality 5kg / ㎡, bentonite is a natural inorganic materials, will not be aging reaction, good durability; and will not cause any adverse impact on the environment is an environmentally friendly material;. 2, has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc., construction is easy and not limited by the temperature of the construction environment, 0 ℃ below can also be constructed. construction simply lay the GCL waterproof blanket flat on the ground, vertical or oblique construction, with nails and washers to fix it, and lap as required;. 3, easy to repair; even after the end of waterproofing (seepage) construction, such as accidental damage to the waterproof layer, as long as the broken part of the simple repair, you can regain the original waterproof performance. 4, relatively high performance to price ratio, very wide range of uses.
