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
