The flexibility of COLETANCHE enables it to adapt to any ground contour and to absorb differential settlement.

UV radiation effects COLETANCHE only at surface level. The thickness of the membrane ensures the integrity of the material and provides long lasting waterproofing.

COLETANCHE can maintain its characteristics for more than 20 years with minimal maintenance even if left unprotected.

COLETANCHE can support ballast, hot asphalt mix, and many other materials without special protection.
