Description :
Waterproof board, also known as geomembrane, anti-seepage membrane, and puncture resistant membrane. Traditionally, geomembranes with a thickness of ≥ 0.8 millimeters are called waterproof boards, which can be classified according to the surface of the board; Light panel and pillar points. Specification and model range; Thickness 0.2-2.5 millimeters, width; 1-6m， Divided into composite and homogeneous (light plate) types, with materials available; LDPE, HDPE, EVA, ECB. Colors available; Black, milky white, semi transparent white, transparent white. The main functions are subway, basement, and tunnel Air raid shelter. Culvert anti-seepage lining, anti-seepage of highway and railway foundations, use of geotextiles, bentonite waterproof blankets and other geotechnical materials in sanitary landfill sites to prevent liquid leakage and gas volatilization, anti puncture in planting and greening projects, mainly used for anti-seepage and isolation in rock engineering, but also for strengthening and protection. It is mainly used for anti-seepage in engineering projects such as earth and rock dams, rockfill dams, masonry dams, concrete dams, tailings dams, sewage storage dams, channels, storage tanks, septic tanks in breeding farms, lotus root ponds, aquaculture, solid waste tanks, etc.
One; feature
Strength - Under the same weight specifications, the tensile strength in all directions is higher than other needle punched non-woven fabrics.
Anti UV light exposure - has extremely high UV resistance.
Extreme high temperature resistance - able to withstand temperatures up to 230 ℃, maintaining structural integrity and original physical properties at high temperatures.
Permeability and plane drainage - The waterproof board is thick and needle punched, with good plane drainage and vertical permeability, and can still maintain this performance after many years.
Creep resistance - Creep resistance is superior to other geotextiles, therefore it has good long-term performance. It can withstand the erosion of common chemical substances in soil and the corrosion of gasoline, diesel, etc.
Ductility - It has a good elongation under certain stress, allowing it to adapt to uneven and irregular surfaces.
Two; characteristic;
1. Excellent flexibility, impermeability, elongation, and wear resistance; 2. Has good isolation and puncture resistance; 3. No chemical pollution. 4. Resistant to acid, alkali, and various chemical substances, with good dimensional stability, good adhesion, and easy construction.

Four; Construction process flow;
1. Preparation before laying:
1.1 Foundation treatment: It is required that the substrate be flat,,,,
1.2 Contact surface with membrane,
2. Laying method:
2.1 Lay along a certain direction without pulling too tightly, leaving a certain amount of expansion and contraction to adapt to the deformation of the substrate.
When laying, adjust the direction of each unit to facilitate welding between the two units.
2.3 After laying, use sandbags to press down to prevent wind and sand from affecting the welding of the next edge.
3. Welding Joint treatment is a key construction procedure, generally using thermal welding method. The surface of the PE film joint is heated to melt it, and then fused into one through pressure.
3.1 For the laid waterproof board, there should be no oil stains, moisture, dust, etc. at the edge joints.
3.2 Before welding, adjust the two edges of the PE film at the joint to overlap a certain width, which is generally 6-8 cm and flat without wrinkles.
3.3 Use a specialized welding machine for welding. The company is responsible for construction/welding
Composite waterproof board; A waterproof material formed by thermal composite of polyester polyester short filament (long filament) geotextile and waterproof board. Width of 1-6 meters, width of waterproof board for tunnels, subways, and culverts; 1-3m， The main specifications are:; 1.0mm/200g，1.2mm/300g，1.5mm/300g，1.5mm/350g，200g/1.0mm/200g，250g/1.5mm/250g。 We can produce according to customer requirements. Composite forms include; Sling style, strip style, fully composite, two fabric composite, one fabric composite. Its main role in engineering; Waterproof and anti-seepage. The product has high physical and mechanical performance indicators such as tensile strength, tear resistance, and burst resistance. It has the characteristics of 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, it can be used in unconventional temperature environments
