Gina and Omega gaskets from Trelleborg Pipe Seals Milford are designed to prevent water ingress in immersed tunnels. The Gina gasket is made from natural rubber combined with varying hardness and is supplied as a closed rectangular frame to seal each sectional element. The Omega seal connects each segment and is made from multiple layers of styrene butadiene rubber and nylon inlayers for durability. The seals enable the transfer of hydrostatic loads and movements between tunnel ends caused by soil settlement, concrete creep, temperature and earthquakes. 800/626-2180;
