Tunnel Segment Gaskets (TSGs)

Tunnel Segment Gaskets (TSG's) are typically located in the groove encircling the pre-cast concrete tunnel segments which are mated together during the installation process providing an efficient water tight seal over the projected design life of the tunnel.

A number of seal design options are available depending on the surrounding geological conditions of the tunnel, all of which are produced at our UK manufacturing facility. We have also developed a patented corner jointing system which eliminates corner point loading - historically the cause of segment cracking where conventional corner joining techniques have been used.
