CTS Cordes

For EPDM Gaskets for tunnel precast segments

For more than 50 years Cordes has been one of the most important manufacturers and suppliers of sealing systems for underground construction. Cordes produce high quality products in three productions centres with extensive production and storage capacity in Germany.

The CTS-Standard seal is a classic mono-compression seal. Embedded within a groove around the tunnel segment and interacting with the opposite seal of the neighbouring segment it seals the circumferential and radial segment joints.

Restoring and contact pressure forces developing from both compressed profiles increase with decreasing joint gaps and produce the grade of water tightness.
