Coletanche: ~repack~

Coletanche is utilized across civil engineering, environmental, and hydraulic sectors.

The product typically consists of four distinct layers:

The defining feature of Coletanche is its chemical resistance. Because the waterproofing agent is bitumen (a hydrocarbon derivative), it is not degraded by contact with oils, fuels, or solvents. Standard HDPE liners can degrade or stress-crack when exposed to certain hydrocarbons, whereas Coletanche remains stable. coletanche

Coletanche resists chemical attacks, making it perfect for containing hazardous waste and contaminated runoff.

Joints are not welded with heat in the traditional sense. Instead, they are torched . Installers use propane torches to melt the bitumen surface on the overlap area. The molten bitumen creates a monolithic, watertight seal as it cools. This method is generally faster and requires less specialized equipment than the hot-wedge welding used for HDPE. Standard HDPE liners can degrade or stress-crack when

In the demanding world of civil engineering and environmental protection, finding a reliable, durable, and versatile waterproofing solution is crucial. , manufactured by Axter, has emerged as a premium bituminous geomembrane (BGM) that meets these high standards. For over 40 years, this engineered product has been protecting soil and water resources worldwide.

Due to the mineral surface coating and the nature of the bitumen mix, Coletanche has excellent resistance to UV radiation, allowing for long-term exposed applications without the need for a protective cover soil. Instead, they are torched

Coletanche is more than just a waterproof barrier; it is a long-lasting, technically superior solution for environmental containment. Whether for a large-scale mining project in the Arctic or a water reservoir, its combination of durability, flexibility, and high resistance makes it a premier choice for engineers worldwide. By selecting Coletanche, projects are investing in the protection of the environment for future generations. If you'd like more specific details, to HDPE geomembranes.
