Physical characteristics of bentonite waterproof blanket: (1) It has excellent waterproof and impermeability. Its static water pressure can reach more than 1.0 MPa, permeability is 5*10-11 cm/s, the mass of bentonite per unit area is 5 kg/m2, and bentonite is a natural inorganic material. It will not have aging reaction and durability. Good; and will not cause any adverse impact on the environment belongs to environmental protection materials. 2. It has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc. It is easy to construct and is not subject to the restriction of construction environment temperature. It can also be constructed below 0 C. During construction, only the GCL waterproof blanket is laid flat on the ground. When the elevation or inclined plane is constructed, the GCL waterproof blanket is fixed with nails and washers and lapped as required. 3. Easy to repair; even after the completion of waterproofing (seepage) construction, if the waterproofing layer is accidentally damaged, as long as the damaged parts are simply repaired, the perfect waterproofing performance can be regained. 4. The ratio of performance to price is relatively high, and it is widely used. 5. The width of the product can reach 6 meters, which matches the international specifications of Geotextiles (membranes) and greatly improves the construction efficiency. Lewu sodium bentonite waterproofing blanket is a new type of environmental protection and ecological composite anti-seepage material. With its unique anti-seepage performance, it has been widely used in civil engineering such as water conservancy, environmental protection, transportation, railway, civil aviation and so on. Foundation treatment and roof sealing of landfill sites, seepage prevention of artificial lakes, reservoirs, channels, rivers and roof gardens, and seepage prevention of famous underground buildings such as basements, subway, tunnels and underground passages.
