Product Introduction:
Geotextile membrane (also known as waterproofing membrane), thickness ranging from 0.2 to 3mm; those thicker than 0.8mm are called waterproof boards. It is a type of waterproof and barrier material made primarily from high-density polyethylene raw resin. The main component is 97.5% high-density polyethylene, with approximately 2.5% of carbon black, anti-aging agents, antioxidants, UV absorbers, stabilizers, and other additives, offering strong waterproof and isolation properties.
Application Scope:
Environmental Protection & Sanitation: including waste landfill sites, sewage treatment plants, power plant settling ponds, industrial solid waste, etc.
Hydrology: Seepage prevention, leak plugging, reinforcement, waterway seepage control, vertical core walls, slope protection, etc. for rivers, lakes, reservoir embankments, and canals.
Municipal Engineering: subway projects, underground construction for buildings, green roof installations, waterproofing for roof gardens, and interior lining for sewage pipes.
Gardens: Artificial lakes, waterways, reservoirs, golf course pond liners, slope protection, green grass waterproofing and moisture-proofing, etc.
Petroleum: Tank lining for chemical plants, refineries, and gas stations to prevent leakage; inner linings and secondary linings for reaction ponds and sedimentation ponds.
Mining: Slurry ponds, leach ponds, ash ponds, dissolution ponds, sedimentation ponds, stockpiles, and bottom liner for tailings anti-seepage.
Traffic Facilities: Basic reinforcement of highways, seepage prevention for culverts.
Agriculture: Anti-seepage for reservoirs, drinking water pools, water storage ponds, and irrigation systems.
Aquaculture: Lined ponds, fish tanks, shrimp ponds, and sea cucumber cultivation slopes in intensive and factory-style farming.
Salt Industry: Saltfield crystallization ponds, brine pond covers, salt pond plastic film covers, etc.
Construction Method:
Do not drag or pull the geotextile membrane roughly during transportation; avoid sharp objects causing injury.
1. Extend from the bottom to the top, avoiding excessive tension. Retain a 1.50% allowance for potential local sinking and stretching. Considering the actual conditions of this project, the slope should be laid from top to bottom.
2. The longitudinal joints of adjacent panels should not be aligned in a single horizontal line; they should be staggered by at least 1 meter.
3. Vertical joints should be located more than 1.50m above the dam foot and bend foot, and should be set on a flat surface.
4. First the slope, then the bottom of the field.
5. When laying along the slope, the direction of the film should be generally parallel to the line of greater slope.
