Supply telephone 1; 3; 5; 6; 1; 7; 5; 1; 0; 4; 9 bentonite composite waterproof blanket (GCL) is a new type of geosynthetics. After it is graded by the natural sodium bentonite additive particles and the corresponding mixed together, with a special technology and equipment, the bentonite particles fixed in between two layers of geotextile, made of bentonite waterproofing blankets, not only has all the characteristics of geotechnical materials, but also has excellent water (permeability) properties. 
 Water-proof mechanism as follows: water swelling bentonite particles, to form a uniform colloidal system in two geotextiles under restrictions, so that bentonite from disorder into order, the expansion of the swelling continued to result bentonite layer itself to dense, which has a waterproof. 
 Bentonite seepage blanket physical characteristics: 
 1, impermeable bentonite blanket has excellent performance of water seepage, permeability than hydrostatic pressure up to 1.0MPa, the permeability coefficient 5 × 10-11cm / s, bentonite is a natural inorganic material, aging reaction does not occur, durability; without any adverse impact on the environment is eco-friendly materials 
 2, bentonite geotextile material impervious blanket has all the features, such as separation, reinforcement, protection, filtration, simple construction and the construction of the ambient temperature is not limited, 0 ℃ the following may also be construction. Construction of the tile just GCL waterproof blanket on the ground, elevation or slope construction, the use of nails and washers to secure it, as required, can overlap. 
 3, bentonite seepage blanket easy to fix; even in the water (seepage) after construction is completed, such as the waterproof layer of accident damage, as long as the site of damage to be a simple repair, you can ever regain the perfect waterproof performance. 
 4, bentonite seepage blanket relatively high cost performance, use very extensive. 
 5, the product width up to 6 meters, with the international geotextile (film) to match the specifications, greatly improving the efficiency of construction. 
 Sodium bentonite GCL composite as a new environmentally friendly eco-impermeable material, with its unique anti-leakage performance has been in the water conservancy, environmental protection, transportation, railway, civil aviation and other civil engineering to be widely used. The basis of waste treatment and landfill capping, artificial lakes, reservoirs, channels, rivers, seepage roof garden, basement, subways, tunnels, underground tunnels and other underground structures were impervious class.
