Meeting the Challenge

Protecting Tunnels
Due to their very nature and location, tunnels can be seriously compromised by hydrostatic pressure and water leakages associated with high water tables. Inadequate waterproofing, cracking and joint failure are problems that will result in the deterioration of concrete and the leaking of water into the tunnel. In the short term, this can lead to the loss of functionality and, over time, compromise the structural integrity of the tunnel itself. Xypex has an extensive track record in the waterproofing and protection of tunnels. In Cut and Cover, Bored and Immersed Tube tunnels, Xypex is recognized by major contractors as a key solution for the tunneling industry.
