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.

Géomembranes Polyéthylène à haute densité (PEHD)

Géomembranes Polyéthylène à haute densité (PEHD)

 


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.
