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.
