Tunnel Seals

Trelleborg has unrivalled expertise in seal design and elastomer technology, and is the world’s leading manufacturer of elastomeric gaskets for immersed tunnels, cut & cover tunnels and bored tunnels.

 

Gina Gasket    The Gina gasket and Omega seal are used between the sectional elements of immersed tunnels to prevent water ingress due to external water pressure.	Omega Seal   Omega Seal was designed as a secondary seal for immersed tunnels in combination with the Gina gasket/seal as the primary seal.
Heinke Tunnel Seal Gaskets   For the segmental lining of bored tunnels Trelleborg Ridderkerk supplies Tunnel Segment Gaskets (TSGs) under the trade name Heinke.	Waterstops, Seals - Tunnels When concrete structures are submitted to outside water pressures in immersed tunnels, the joints between concrete sections are made watertight with waterstops.
