COLETANCHE bituminous geomembrane installation advices

The COLETANCHE geomembrane is compatible with most substrates: it adapts to ground movements and differential settlements.

❶ Laying rolls of Coletanche waterproofing geomembrane



A manual or hydraulic beam is used to unroll a COLETANCHE membrane. Installing it is straight forward and can be done by a small specialised team.

❷ Welding of the waterproofing membrane

Manual welding is achieved with a gas or hot air torch. The protective film must be removed from the overlapping zone.

❸ Anchoring and joining the membrane

COLETANCHE can also be directly welded to concrete substrates. Its flexibility offers easy  welding solutions on worksites:

  • Connection on metal manhole head,
  • Other types of membranes,
  • PVC pipes,
  • Metal poles.

❹ Quality control of the waterproofing membrane 

  • A range of quality control procedures and testing are available to designers
  • The appropriate quality control will depend on the specifics of the project
