Groundbreaking know-how

Tunnel sealing

When sealing tunnels by means of injections, DMI Injektionstechnik GmbH can draw on an enormous amount of technical knowledge due to the vast array of tunnels it has already sealed.

This is especially important when dealing with complicated causes of damage in segment tunnels. We restore concrete ourselves in accordance with the German Additional Technical Contract Conditions and Guidelines for Civil Engineering Works (ZTV-ING).

We can thus offer our customers an all-in-one restoration service.

We seal and restore the following in tunnels:

  • Section joints and sections
  • Tunnel foils
  • Exterior and interior joint tapes
  • Sealing blocks
  • Gravel pockets
  • Pipe joints
  • Cracks
  • Connection joints to sealing blocks
  • Construction joints, etc.
