GEOMEMBRANES

 

ANDEX supplies geomembranes with ISO 9002 certification, made with “virgin” resin, whose resistance is adequate for exposure to weathering; being low cost alternatives for applications in Environmental Engineering: reservoirs, settlers, channels, pads, pits, ponds, emergency containment systems, stabilization and oxidation ponds, landfills, waterproofing of structures, etc.

ANDEX has a wide range of Geomembranes:

  • HDPE, LDPE, VLDPE y PVC.
  • Smooth, structured on one side, or on both sides.

            Single color on both sides, or 2 different colors.

  • Reinforced Polyolefins and PVC.
  • Geomembranes with different thicknesses from 0.5 mm – 2.5 mm.
  • Floating covers to reduce losses due to evaporation.

According to the type of project we offer geomembranes of:

Standard grade geomembranes
High Density Polyethylene (HDPE)
  • Semi rigid.
  • Variable thicknesses.
  • Resistance to chemical and biological degradation and to UV rays.
  • Smooth, rough, or structured simple or double.

Low Density Polyethylene (LLDPE)
  • Moderate Flexibility.
  • Variable thicknesses.
  • Smooth, rough, or structured simple or double.
  • Resistance to chemical degradation – biological and UV rays.
Polyvinyl Chloride (PVC)
  • High reflectivity.
  • Variable thicknesses.
  • High flexibility.
  • Smooth, textured, and non-slip.
Special geomembranes 

They are geomembranes technically treated with special stabilizers, or different manufacturing processes, achieving a breakthrough in flexible geomembrane technology.

  • Different thicknesses.
  • High flexibility.
  • Excellent resistance and longevity properties.
  • Great chemical resistance – biological and UV rays.
Applications:
  • Reservoirs
  • Dykes and dams
  • Control of algae
  • Odor control
  • Vapor barriers
  • Heap leach pads
  • Landfills
  • Irrigation channels
  • Oxidation ponds
  • Evaporation control
  • Water storage
  • Thermal insulation covers
  • Waterproofing of structures
