TunnelDrain – the new alternative to strip drains

Nordic Geo Support in partnership with Dolenco is proud to offer the innovative TunnelDrain system

Strip drains are often used in situations where there is water ingress over a larger area in the ground and it cannot be isolated in discrete points. The main disadvantage of the strip drains is that they prevent the rock support bonding to the rock. The innovative TunnelDrain overcomes this while at the same time providing effective water management.
