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.

Contact us for more information and actual cases.

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 6 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


Fast installation. Paula has done most of the installation in Kattleberg Train Tunnel in Sweden.
