Geomembranes are made of impermeable geosynthetic material, from thin continuous plates of polymers:
- high density (HDPE),
HDPE (High Density Polyethylene) is the most commonly used geomembrane and is the preferred choice for lining projects due to its durability, resistance to higher temperatures and relatively inexpensive material.
The best feature of a geomembrane is its chemical and UV resistance, which makes it suitable for use in large areas.
Membranes are available in different thicknesses, and structures (smooth, rough) these depend on application requirements and environmental conditions.
- They create an impermeable barrier that prevents harmful chemicals from leaking into the environment (landfills/landfills),
- Use in wastewater treatment plants,
- They prevent leakage of drinking water,
- They also serve as linings in reservoirs, ponds, artificial lakes and pools,
- Use in the construction of tunnels and underground structures to provide waterproofing and protection against water ingress.
- Stabilization of slopes and prevention of soil erosion,
- Geomembranes are used in conjunction with other geosynthetic products to control fluid movement and ensure containment in projects related to mining, sewage treatment and canal construction.
