COLETANCHE® is a bituminous geomembrane waterproofing system, unique in terms of its 5.10m width. COLETANCHE® geomembrane associates an elastomeric bitumen based binder and an internal structure made from non-woven polyester geotextile; it is designed to guarantee excellent mechanical and chemical resistance over the long term

  • Resistance to aggressive environments even without adding an anti-puncture geotextile

  • Compatible with all subgrades and covering Material (hot-mix, asphalt, concrete, stone, gravel)

  • ​Excellent resistance to ageing (UV, weather, biological agents and oxidation)

  • Suitable for extreme weather conditions (rain, wind, extreme cold - 40°C)

  • Remarkable dimensional stability and flexibility guaranteeing permanent support with the supporting ground. 

Key Benefits:

Solution for Containment Applications

Solid Waste Storage - Colmar, France

Used as a liner to control leachate and protect groundwater and used as a cover to prevent rain water infiltration into the waste.

Tailings Pond - Toromocho, Peru

Used to line leachate, waste water and tailings retention ponds due to its resistance to biological and chemical attack.

Biogas Barriers - Toronto, ON

To stop undesirable gas flows from migrating through the floor into residential or commercial buildings built on or near former oil fields, landfill, or industrial facilities. 

Dams - Cerro Lindo, Peru

To waterproof dams, and/or renovate the upstream waterproof facing of dams.

Irrigation Canal - Naches, WA

To line canals used to transport water to minimize losses by infiltration and protect the embankments from erosion.

Drinking Water Reservoir - Los Angeles, CA

To waterproof basins and water storage facilities used for stormwater control, drinking water or recreation.

Wastewater Storage - Estree Mons, France

Used to line leachate and waste water retention ponds due to its resistance to biological and chemical attack.

Railroads - Crawford, NE

To stabilize railway and protect the ballast. 

Project Profiles

A strict quality assurance plan implemented during manufacturing as well as on-site installation of the geomembrane allows to guarantee maximum quality. The welded seams can be checked using standardized methods and especially ultrasound testing.

With its COLETANCHE® brand, AXTER proposes a range of geomembrane construction solutions for public works and civil engineering projects around the world. The high technical performance of these solutions makes them suitable for a wide range of applications for both new build and renovation projects in various sectors: environment, hydraulics, transport and underground construction.

Bituminous Geomembrane

High performance and Adaptability to Every Type of Climate and Environment

Intimate Contact

  • Intimate contact is crucial for a liner system to be highly effective in reducing the extent of leakage from a hole. Coletanche is virtually wrinkle free! 

  • Remarkable flexibility and dimensional stability thereby guaranteeing permanent contact with the ground support.

Toughness & Durability

  • Durability under real conditions exceeding 40 years

  • Resistant to UV rays

  • High resistance to puncture and tearing.

  • Capacity to be covered by a wide range of materials: asphalt, macadam or poured concrete.

  • Friction angle up to 34°, greater than any other geomembrane.

  • Resistance against chemical products, biological agents and oxidation.

Easy & Economical Maintenance

  • Easy to weld or bond with concrete and other penetrations in the open and under water

  • ​COLETANCHE® is compatible with most materials and can therefore be laid on the majority of soil types without any kind of protection allowing exposure to UV if required.​​​​

Straight-forward Installation

  • No specialized technicians required.

    • Penteco trains your labour crew how to install in just a few days

    • You can rent the equipment  from us! ​​​​

  • Significant width of 5.1 m or 16.7 ft​​​​​​​

  • Installation possible in extreme weather conditions (rainfall, wind, cold temperatures down to -40 °C or -104 °F))

  • High surface mass allowing installation in strong wind conditions
