Product Introduction:
HDPE geomembrane (also known as waterproofing membrane), thickness ranging from 0.2mm to 3.0mm; thickness above 0.8mm is referred to as waterproofing board. It is a waterproof and barrier material based on high-quality polyethylene primary 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 in waterproofing 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, leak plugging, reinforcement of rivers, lakes, reservoir embankments, waterway seepage prevention, vertical heart walls, slope protection, etc.
Municipal Engineering: subway projects, underground infrastructure of buildings, green roofs, waterproofing for rooftop gardens, internal lining of sewage pipelines, etc.
Garden: Artificial lakes, waterways, reservoirs, golf course pond liners, embankment protection, green lawn waterproofing and moisture-proofing.
Petroleum: Tank lining for chemical plants, refineries, and gas stations, inner linings for reaction pools, sedimentation pools, and secondary lining layers.
Mining: Leach tanks, heap leach pads, ash ponds, dissolution tanks, sedimentation tanks, stockpiles, and bottom liner for tailings prevention.
Traffic Facilities: Road foundation reinforcement, culvert seepage prevention.
Agriculture: Leak-proofing for reservoirs, drinking water ponds, water storage ponds, and irrigation systems.
Aquaculture: Intensive and factory-style pond liners, fish ponds, shrimp ponds, sea cucumber pen slopes, etc.
Salt Industry: Saltfield crystallization ponds, brine pond covers, salt pond plastic covers, etc.
Construction Method:
Do not drag or pull the geotextile membrane roughly during transportation; avoid sharp objects piercing it.
1. Extend from the bottom to the top, but do not pull it too tight. Leave a 1.50% allowance for potential local sinking and stretching. Considering the actual circumstances of this project, the slope should be laid in an order from top to bottom.
2. The vertical joints between adjacent panels should not align on a single horizontal line, and they should be staggered by more than 1 meter.
3. Vertical joints should be located more than 1.50m above the dam foot and bend corners, and should be set on a flat plane.
4. Slope first, then field bottom.
5. During slope laying, the direction of the film should be primarily parallel to the gradient line.
