Omega Seal

Since the 60’s Trelleborg has manufactured a large number of Omega seal joints. Originally the Omega Seal was designed as a secondary seal for immersed tunnels in combination with the Gina gasket/seal as the primary seal.

Applications for the Omega Seal have now expanded to bored tunnels, aqueducts and ship lifts. Using the same construction techniques and materials as utilized in the original Omega shaped seal; the range has been expanded to flat seals.

Example of Omega Construction

Trelleborg has manufactured a flat Omega seal 1.4 meter (!) in width for an aqueduct in Germany. The Omega Seal provides the unique properties to withstand high water pressure in combination with large movements in all directions. The Omega Seal provides an ideal solution for joints where large gap movements are expected as a result of temperature effects and/or settlement.
