What is the waterproof effect of bentonite waterproof blanket?
Bentonite waterproof blanket is a new type of blanket waterproof material made of bentonite particles fixed between geotextiles and plastic woven fabrics. The anti-seepage principle of bentonite waterproof blanket: bentonite can expand 5-10 times when it encounters water, the anti-seepage hydrostatic pressure can reach more than 1.0MPa, the permeability is 5×10-11m/s, and the mass of bentonite per unit area is 5kg/m2. Waterproof performance, natural inorganic materials, no aging reaction, long service life of 50 years.

The usefulness of bentonite waterproof blanket
GCL bentonite waterproof blanket is mainly used for anti-seepage or sealing in civil engineering, hydraulic engineering and environmental protection engineering, such as anti-seepage design of channels, reservoirs and dams. The seal at the bottom of the dump can be used alone or in combination with a compacted clay liner or geomembrane for impregnation. When the scheme allows clay, bitumen, concrete geomembrane and GCL to be used as the sealing layer, GCL bentonite waterproof blanket is competitive.

The role of bentonite waterproof blanket
As a waterproof construction method, bentonite waterproof blanket has certain advantages compared with other waterproof constructions, and the requirements for the bottom layer are relatively low. First, the concrete bottom layer is firm, the surface is flat, and there are no cracks, peeling, looseness, etc.; second, the necessary leveling of the concrete surface is carried out, and all internal and external corners are chamfered with bentonite particles or bentonite sealant to 5cmx5em; three, in the scope of bentonite construction Internally drilled, clean and free of debris.

Structural requirements of bentonite waterproof blanket
Bentonite waterproof blanket, at present, landfill is the main garbage treatment in my country. Many sewage generated in the process of landfill will seriously pollute surface water and groundwater sources, destroy people's daily environment and living conditions, and affect ecological balance. If a landfill leaks during operation, the cost of compensation can be considerable.

Discussion on Construction Method of Drainage Network
The drainage network is mainly used for drainage of landfills, roadbeds and inner walls of tunnels. In the transportation infrastructure such as railways and highways, the safety and service life of the project are closely related to the self-drainage system, and the earthwork composite material is an important part of the drainage system.

How does the drain mesh join seams and laps?
Drainage network, also known as composite soil hole drainage network, is a new type of pore synthetic material made of Nansha fused mesh, with high pore density and high internal pressure, and has the functions of water collection and horizontal drainage. The drainage network can not only drain water, but also discharge the biogas produced by fermentation from the soil (especially garbage waste), which is especially suitable for landfills.
