Polyethylene (PE)

Polyethylene geomembranes are ideal for waterproofing works that require long-term durability. PE high chemical stability makes it the most widely used material for landfill, tailings ponds or water treatment basin projects.

POLYETHYLENE OF LOW LINEAR DENSITY (LLDPE)

LLDPE geomembranes have excellent resistance to multiaxial elongation. They are generally used in applications where differential settlement is expected, as they can deform without losing their properties. They are available in two surface finishes. The smooth finish is used in flat terrain while the textured finish provides the friction needed to retain granular materials in the embankments. A white finish is also offered, which is more UV-resistant and reduces the expansion of the geomembrane on sunny days.

PropERTIES

High elongation at break
Puncture and tear resistance
High multiaxial elongation resistance
Chemical stability

ADvantages

Flexible and easy to use
Sustainable
Factory pre-weldable

Applications

Landfills
Retention basins
Treatment of contaminated soil sites
Snow deposit
Waterproofing of ditches, lightweight embankments, etc.

HIGH DENSITY POLYETHYLENE (HDPE)

HDPE geomembranes are made from premium grade resins and are ideal for structures requiring low permeability and long service life. They are often chosen in waterproofing landfills and various pools for their chemical inertness and resistance to UV. They are available in two finishes. The smooth finish is used in flat terrain while the textured finish provides sufficient friction to retain granular materials in the embankments. A white finish is also offered, which is better resistant to UV and decreases the expansion of the geomembrane on sunny days.

PropERTIES

High tensile strength and elongation at break
UV resistance
Chemical inertness

ADvantages

Durable and flexible
Aging resistance

Applications

Landfill
Retention pond
Treatment of contaminated land site
Snow deposit
Waterproofing of ditches, lightweight embankments, etc.

REINFORCED POLYETHYLENE

These geomembranes are composed of a weaving of HDPE strips laminated on each side with a film of LLDPE. The weaving provides mechanical properties of the geomembrane, while films provide sealing and resistance to abrasion. The result is a flexible, dimensionally stable, durable geomembrane. Various thicknesses are available, from 0.20 to 1.13 mm for all types of work

PropERTIES

Excellent resistance to tearing and perforation
High UV protection
Flexible in cold weather
Several finishes available
Possibility of laminating non-woven geotextiles to obtain a geocomposite

ADvantages

High flexibility for factory prefabrication
Aging resistance
Minimum expansion and thermal contraction
Increased durability
Economical

Applications

Retention ponds
Contaminated soil treatment sites
Snow deposits
Temporary heap recovery
Waterproofing of ditches, lightweight embankments, etc.
