Underground works
COLETANCHE GC is a bituminous geomembrane waterproofing system for buried structures, with CETU technical approval. It eliminates the risk of water infiltrating from the natural ground into buried structures like underground structures, tunnels, etc.
- Applications
- Coletanche advantages
- Other characteristics
- Covered trenches,
- Partially covered hoppers,
- Structures under road, motorway and railway platforms,
- Buried civil engineering structures,
- railway transport stations,
- storage facilities, technical premises and car parks,
- Animal Pass, Ecoduc.
- Compatibility with concrete substrate to waterproof backfilled underground structures,
- It can be laid perpendicular to the structure’s axis,
- Flexibility and dimensional stability: it adapts to a structure’s geometry without creating tension at the joints.
- Excellent performances over time, even in exposed conditions.
- Long term mechanical (tension, puncture, elongation) and chemical (leaching, acid, UV, gas) resistance
- Compatible with all types of materials (concrete, steel, PVC, etc) by sealing or gluing.
- Dimensional stability: no sensitive to expansion phenomena and stress cracks.
