The RockDrain-system
Drainage, fire and frost protection in tunnels and underground structures.
The RockDrain system is a reliable, cost-effective, safe and sustainable system for drainage, fire and frost protection of tunnels and underground structures.
For example; When constructing a 16 km tunnel in Sweden it is possible to reduce costs by approx. SEK 1.5 billion compared with full molding and membranes.
When a better solution comes – use it!
