Tunnel Segment Gaskets (TSGs)
VIP’s tunnel segment gaskets are manufactured from high-grade rubber compounds, which meet many internationally recognised standards including EN681-1 (the material requirements standard for pipe and joint seals used in water and drainage applications).
Elastomeric (rubber) gaskets are one of the most effective waterproofing systems for segmentally lined tunnels and shafts where protection is required against water ingress or for retention in tunnels used for fluid transport or storage.
Each profile manufactured by VIP has been specifically designed so that the volume of rubber does not exceed that of its corresponding groove and the compression performance of the gasket is equal along the entire face of the gasket.
VIP offers a range of tunnel segment gasket profiles to suit various applications and specifications. In addition, our team of technical engineers have the experience and detailed knowledge to design bespoke gaskets for unique conditions.
Our dedicated test facility allows us to simulate the segment assembly, build conditions and sealing pressures as specified by the design.
