Tunneling & Mining

Tunnel protection

Tunnel wall drainage & protection Railway support Soil reinforcement Vibration damping

High performance drainage is a basic need for a long service life for tunnels.

Passage of train wheels on a railway track causes a dynamic vertical load on the sleepers and ballast.

When infrastructure is constructed on a weak sub-soil, measures need to be taken to increase the bearing capacity of this soil.

Traffic, and especially railway traffic causes vibrations that can disturb the environment.
