What is a Geomembrane? Why is it so effective?
A geomembrane is a very low permeability sheet made primarily from polymers (like polyethylene, PVC). It can be regarded as a flexible, durable, and seamless barrier, effectively preventing the migration of liquids and gases.
When we construct an artificial lake, a wastewater treatment pond, or a landfill, what is the most concerning issue? It is leakage. Whether it's the loss of precious water resources or pollutants seeping into the ground and damaging the ecological environment, it is unacceptable. And geomembrane is the ultimate solution to this challenge.
Its Core Advantages:
Very Low Permeability
Excellent Chemical Stability
Superior Tensile Strength and Elongation
Good Weldability
High Cost-Effectiveness
Common Types of Geomembranes and Their Applications
Not all geomembranes are the same. The right product must be selected for different engineering needs.
HDPE Geomembrane (High-Density Polyethylene)
Characteristics: High strength, excellent chemical resistance, strong UV resistance, longest service life. The most widely used type.
Applications: Landfills (core liner), Sewage Treatment Plants, Hazardous Waste Sites, Large Reservoirs/Artificial Lakes.
LLDPE Geomembrane (Linear Low-Density Polyethylene)
Characteristics: Softer than HDPE, better elongation and stress crack resistance, adapts better to uneven settlement.
Applications: Aquaculture Ponds, Landfill Covers, Impermeability Projects with Complex Topography.
PVC Geomembrane (Polyvinyl Chloride)
Characteristics: Excellent flexibility, easy installation and laying, relatively low cost.
Applications: Landscape Water Features, Irrigation Canals, Basement Moisture Proofing.
Core Application Areas of Geomembranes
Environmental Engineering:
Landfills, Sewage Treatment, Industrial Tailings Ponds.
Water Conservancy & Water Features:
Reservoirs, Artificial Lakes, Aquaculture Ponds, Irrigation Canals.
Construction & Municipal Engineering:
Basement/Tunnel Waterproofing, Green Roof Waterproofing.
Five Key Points for Selecting High-Quality Geomembranes
