Nordic Geo Support offers a range of products for the important task of controlling water ingress – both in the temporary and permanent cases. This includes the innovative TunnelDrain.
TunnelDrain – the new alternative to strip drains (from Dolenco)
TunnelDrain is ideal for drained excavations whether this is rock tunnel or mine or a piled excavation or tunnel in soft ground.
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.
