Tunnels

Tunnels

Trelleborg is the global market leader in sealing systems for tunnels. Whenever a tunnel is under a river or sea or when the groundwater table is high, the concrete tunnel elements need to be sealed against water ingress. We have a long reference list of tunnel project all over the globe for which we have designed and supplied the sealing system.

Immersed Tunnels Solutions and Products

Trelleborg's Gina and Omega gaskets are the premier sealing system for immersed tunnels, often in combination with our waterstops for the segmental joints.

Bored Tunnels Solutions and Products

For the segmental lining of bored tunnels Trelleborg supplies tunnel segment gaskets (TSGs). Since 1985, Trelleborg TSG have been successfully supplied to major segmentally lined tunnel projects around the world. The TSGs, which are located in precast grooves encircling the mating faces of each segment, give a secure rubber-to-rubber waterproof seal as soon as the segments are bolted together.

For cut and cover tunnels as well as for entries and exits of immersed tunnels, our rubber waterstops are highest quality solution available in the market.
