Immersed tunnels The Gina gasket and Omega seal are used between the sectional elements of immersed tunnels to prevent water ingress due to external water pressure. This combination of seals not only allows for sealing but also for the transfer of the hydrostatic loads and movements between the tunnel ends due to soil settlement, creep of concrete, temperature effects and seismical activity. The designs are generally based on the expected tunnel lifetime of 120 years. Waterstops Waterstops are used to accommodate water pressure as well as the natural movement between the individually poured...

Bored tunnels

For the segmental lining of bored tunnels Trelleborg Ridderkerk BV supplies tunnel segment gaskets (TSGs). For years Trelleborg TSGs have been successfully supplied to major segmentally lined tunnel projects around the world. The TSGs provide a secure rubber-to-rubber waterproof seal as soon as the segments are together. They are located in precast grooves encircling the mating faces of each segment. The low compression set and stress relaxation values of the elastomeric compound enable elastomeric TSGs to recover under reduced applied load. Thereby maintaining a positive seal between...

The Dutch have always had to struggle with the sea to “keep their feet dry”. Therefore special construction methods were engineered to ensure watertightness in structures such as tunnels. Cut & Cover tunnels are widely used for shallow tunnels. The tunnel consists of an in-situ cast concrete structure in an excavated trench. The trench will later be covered. These concrete sections are often too big to be poured as one monolithic unit and therefore have a number of construction joints. Waterstops are used to accommodate water Trelleborg Ridderkerk is the specialist in the design pressure as...
