Customized Composite Geomembrane For Dam Canal
Composite geomembrane is a geotechnical material composed of high-strength synthetic fibers and geomembrane materials.
High strength, corrosion resistance, aging resistance, anti-seepage and anti-leakage. Because it is compounded with geotextile, it also has certain water permeability and air permeability, which can maintain the drainage and ventilation properties of the soil.
Composite geomembrane is a geosynthetic material composed of a high-density polyethylene film and a non-woven geotextile layer.
Specifications: One geotextile and one geomembrane, two geotextiles and one geomembrane, two geomembranes and one geotextile, one geotextile and multiple geomembranes.
Material：PP/PET and HDPE
Width: 1-7m
length according to customer needs
Features:
1. Strong anti-permeability: The composite geomembrane has a high-density polyethylene film layer, which can efficaciously end the penetration of water and preserve away from damage to constructions or soil by way of the use of water.
2. High strength: The composite geomembrane is made of non-hazardous geotextile and high-density polyethylene film, which makes it have immoderate tensile strength and tear resistance, and can face up to positive exterior forces and compression capabilities.
3. Good local weather resistance: Composite geomembrane has specific local weather resistance, can be used for a prolonged time under amazing nearby climate conditions, and is now no longer handy to age and flip out to be brittle.
4. Environmental protection: The composite geomembrane is made of non-toxic and non-polluting materials, which is environmentally fantastic and does no longer pollute soil and water sources.
Application:
1. Water conservancy projects: used for anti-seepage, anti-leakage and security projects, such as dams, rivers, ponds and water remedy plants, etc.
2. Basic engineering: It can be used for the foundation of buildings, roadbed of highways, tunnels, bridges and anti-seepage of underground projects.
3. Agriculture and horticulture: It can be used in farmland anti-seepage, greenhouses, difficulty drainage channels and special agricultural tasks to provide soil water retention and cease fertilizer seepage.
4. Environmental engineering: It can be used in environmental initiatives such as landfills, waste treatment plants, and sewage remedy plant existence to stop leakage, seepage, and groundwater sources.
