We develop compression seals that are lined with prefabricated segments made of reinforced concrete. We have already created numerous profile geometries, but we also develop special custom solutions in accordance with the requirements of the specific tunnel construction.
We offer seals that can be anchored directly into the segments. This significantly enhances the quality of the applications and ensures low production costs and low adhesive consumption.
Datwyler expanding gaskets are based on an expandable EPDM blend – an advanced technology that delivers durability and chemical resistance.
This area encompasses a multiplicity of seals for tunneling machines and the sealing of the starter shaft. Precise solutions ensure safe operation of the tunnel drilling apparatus and start of drilling.
