Waterproof board is a type of anti-seepage material made from polymer materials, which can prevent liquid leakage and gas evaporation. Widely used in construction, transportation, subways, tunnels, and engineering projects.

Waterproof board, also known as geomembrane, is commonly referred to as a waterproof board for geomembranes with a thickness of>=0.8mm< 0.8mm geotextile membrane is a type of anti-seepage material made from polymer materials, which can be divided into homogeneous waterproof board and composite waterproof board

function

The main function of waterproof board is to prevent liquid leakage and gas volatilization. The role of waterproof board in rock engineering is mainly to prevent seepage and isolation, but it also plays a role in strengthening and protecting. It is mainly used for anti-seepage in engineering projects such as earth and rock dams, rock fill dams, masonry dams, concrete dams, tailings dams, sewage storage dams, channels, and storage tanks. It is also used for anti-seepage lining in subways, basements, and tunnels, anti-seepage in highway and railway foundations, and in conjunction with geotextiles such as long filament geotextiles and bentonite waterproof blankets in sanitary waste landfills.

concept

Waterproof board HDPE waterproof board (new HDPE waterproof board) used for underground anti-corrosion and anti-seepage works is formulated based on ordinary waterproof board, selected high-quality low-pressure high-density polyethylene raw materials, scientifically proportioned carbon black, anti-aging agent, antioxidant, ultraviolet absorber, stabilizer and other auxiliary materials, and made by three-layer co extrusion technology with the most advanced fully automatic geotechnical production equipment in the world at present. This production line is highly automated, from order input, formulation, feeding, processing to quality monitoring, all of which are fully controlled by computers and operated strictly based on scientific data. And it can simultaneously use the latest raw materials (with super strong tensile strength), such as Metallurgy and traditional PE, EVA, LLDPE, etc. All products are produced according to the American ASTM D standard, meeting or exceeding national standards. The product specifications are complete, with a thickness of 0.2mm-2.5mm and a width of 1m-8m, meeting the anti-seepage and anti-corrosion requirements of artificial lakes, sewage tanks, reservoirs, environmental protection, mining and chemical projects.

purpose

The waterproof board has a width of 4-6m and a weight of 200-1500g/square meter. It has high physical and mechanical performance indicators such as tensile strength, tear resistance, and burst resistance. The product has high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, crack prevention and strengthening in water conservancy, municipal engineering, construction, transportation, subway, tunnel, and engineering construction. Due to the use of polymer materials and the addition of anti-aging agents in the production process, this waterproof board can be used in unconventional temperature environments. It is commonly used for anti-seepage treatment of dams, drainage ditches, and anti fouling treatment of waste sites.
