Geotextile膜
HDPE geomembrane is one type of geosynthetic material, with the application of geosynthetic materials originating in the 1950s. Domestic geomembranes were part of China's 8th Five-Year Plan. HDPE geomembrane is a waterproof and barrier material produced from high-density polyethylene (HDPE) resin (with a density of 0.94 g/cm³ or higher).

Performance Features:
1. Free from chemical additives and heat treatment, it is an environmentally friendly building material.
2. Features excellent mechanical properties, good permeability, and resistance to corrosion and aging.
3. Features strong anti-submersion and corrosion-resistant structure, fluffy with excellent drainage properties.
4. Excellent friction coefficient and tensile strength, with geosynthetic reinforcing properties.
5. Features include isolation, anti-filtering, drainage, protection, stabilization, and reinforcement.
6. Adaptable to uneven subgrades, resistant to construction force damage, and with low creep.
7. Good overall continuity, lightweight, and easy to install.
8. Being permeable materials, they offer excellent anti-filtering and isolation properties, strong puncture resistance, and thus provide excellent protective performance.
Application:
Primarily used in anti-seepage lining projects for landfill, wastewater treatment, water conservancy, agriculture, transportation, high-speed rail, tunnels, airports, buildings, and landscapes.
Construction Plan Specifications:
Do not drag or pull the geotextile membrane roughly during transportation; avoid sharp objects piercing it.
1. Extend from the bottom to the top, avoiding tight stretching. Retain a 1.50% allowance for localized sinking and stretching. Considering the actual circumstances of this project, the slope should be laid from top to bottom.
2. The longitudinal joints of adjacent panels should not align on a single horizontal line; they should be staggered by more than 1 meter.
3. Vertical joints should be placed more than 1.50 meters away from the dam's foot and bend area, and should be located on a flat surface.
4. First the slope, then the bottom of the field.
5. During slope laying, the direction of the membrane should generally be parallel to the line of greater slope.
Product Specifications:
0.3mm to 3mm, width 1m to 8m, length as per customer's requirement.
