The use PVC-P geomembranes as a waterproofing for cut and cover tunnels is a sophisticated and safe technology to protect the construction against destructive influences of the water.

The conception of the waterproofing system in Cut and Cover tunnels demands an exact planning of the system, a good collaboration and discussion between producer, designer of the project, main contractor and installer. Too often the importance of a waterproofing is underestimated already by the designer with the consequence that the execution of the waterproofing works are immensely difficult, sometimes even impossible to achieve a complete water tightness (Connection between Cut and cover section with working space and Cut and cover section without working place).
