WHAT IS
GEOMEMBRANE?

Geomembranes are impermeable polymeric liner sheets used as protective barriers and insulation systems in industrial, environmental, agricultural, and civil engineering projects. They provide excellent resistance against UV radiation, chemicals, moisture, and environmental conditions while offering long service life and high flexibility.

Types of Geomembranes:

  • HDPE Geomembrane (High Density Polyethylene)
    High chemical resistance, UV resistance, and durability for heavy-duty industrial.
  • LLDPE Geomembrane (Linear Low Density Polyethylene)
    More flexible & suitable for tunnels, settlements, and requiring high elongation.
  • PVC Geomembrane
    Flexible membrane used for insulation and construction applications.
  • VLDPE, EPDM, CSPE, FPP and specialty membranes
    Designed for specific industrial and environmental applications.

APPLICATIONS

  • Agricultural water ponds
  • Aquaculture and fish farms
  • Landfills and waste containment
  • Oil, gas & petrochemical industries
  • Mining and heap leach pads
  • Water & wastewater facilities
  • Irrigation canals
  • Tunnels and hydraulic structures
  • Green roofs and waterproofing systems
  • Artificial lakes and industrial lagoons & etc
