Coletanche is a made by combining:
| Feature | Description | |---------|-------------| | | Minor punctures close up under pressure/heat due to bitumen flow. | | High flexibility | Remains flexible at low temperatures (down to -20°C/-4°F). | | UV & oxidation resistance | Protective coating prevents aging; suitable for exposed applications. | | Chemical resistance | Resists salts, acids, hydrocarbons, and many industrial effluents. | | Low permeability | Typically <10⁻¹² m/s (better than many HDPE geomembranes). | | Reinforced strength | Geotextile backing provides puncture and tear resistance. | coletanche
Because it is a bituminous material, it can be installed in cold, damp, or windy conditions where synthetic membranes might fail, enabling continuous construction schedules. Coletanche is a made by combining: | Feature
