Walls and ceiling of a tunnel after sealing and concrete repairs.

Our experience resulted from a few thousands meters of sealed and repaired tunnels in power engineering, industry and water menagement:
- dam tunnels,
- transport tunnels,
- cable ducts,
- backpack grouting,
- lining,
- sealing joints,
- crack injection,
- performance in temperatures close to zero C deg.
