DELTA®-MS Tunnel LinerHigh capacity drainage with a continuous and safe system of channels.
DELTA®-MS Tunnel Liner is a sensible and reliable solution for coping with the influx of water in tunnel projects of any kind. Installed with its dimples facing outward, i.e. towards either the rock substrate of a shotcrete layer applied for stabilization and filtration purposes, the air gap between the dimples will form a continuous system of channels.
This continuous drainage space will convey any water coming from the ground towards the drainage system without impeding its flow. The inner waterproofing layer of the system, which may be attached directly to the dimpled sheet by any of a number of methods, is never impacted by water pressure. DELTA®-MS Tunnel Liner may serve as permanent shuttering, in structures made of waterproof concrete, keeping away any seepage water while the concrete sets.
