Product Introduction:
HDPE geomembrane (also known as waterproofing membrane), thickness ranging from 0.2mm to 3.0mm; those over 0.8mm thick are called waterproof panels. It is a waterproof and barrier material made primarily from high-quality 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. Strong waterproof and isolation properties.
Product Applications:
Environmental Protection and Sanitation: Waste landfill sites for domestic waste, sewage treatment plants, power plant settling ponds, industrial, and hospital solid waste, etc.
Hydrology: Seepage prevention, leakage plugging, reinforcement, waterway seepage prevention, vertical heart wall, slope protection, etc.
Municipal Engineering: subway projects, underground construction for buildings, green roof installations, waterproofing for rooftop gardens, and internal lining for sewage pipelines.
Garden: 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, inner and secondary linings for reaction ponds and sedimentation ponds.
Mining: leach ponds, heap leach pads, ash ponds, dissolution ponds, sedimentation ponds, stockpiles, and anti-seepage linings for tailings.
Traffic Facilities: Basic reinforcement of highways, seepage prevention for culverts.
Agriculture: Leak prevention for reservoirs, drinking water ponds, water storage ponds, and irrigation systems.
Aquaculture: Intensive and factory-style pond liners, fish ponds, shrimp ponds, sea cucumber cultivation slope protection, etc.
Salt Industry: Saltfield crystallization ponds, brine pond covers, salt pond plastic tarpaulins, etc.
Construction Method:
Avoid dragging or pulling the geotextile membrane roughly during transportation to prevent injury from sharp objects.
1. Extend from the bottom to the top, avoiding excessive tension, and leave a 1.50% allowance for local sinking and stretching. Considering the actual conditions of this project, the slope is laid in an order from top to bottom.
2. The vertical joints between adjacent panels should not align on a single horizontal line; they should be staggered by more than 1 meter.
3. The longitudinal joint should be located at least 1.50m above the dam foot and bend foot, and should be set on a flat surface.
4. First the slope, then the field bottom.
5. During slope laying, the orientation of the film should be generally parallel to the slope line.
