TRS-Metode – The RockDrain Solution

Nearly all tunnels and underground constructions encounter water leaks. To keep the tunnel dry the contractors need a sustainable solution to drain and lead the water from the tunnel surface down to the main drainage.

The solution to this problem is the RockDrain System:

  • New tunnels
  • Rehabilitations e.g. in metros with limitated space. 
  • At least 120 years lifespan
  • Builds only 8 cm on tunnel surface
  • Monolittic – not affected by suction and pressure forces
  • Fireproof
  • Waterproof
  • Frostproof
  • Quick repair if impact – done in a few hours
  • Engineering and construction management
  • When The RockDrain System has been installed, the tunnels are ready for technical installations.
  • Easy to install
  • Cost-effective
  • Reliable
  • Low LCC and LCA
