This dimpled sheet with 8 mm dimple height and an integrated plastic mesh has made a name for itself as an outstanding receiving surface for shotcrete on inner tunnel shells.

In new tunnel construction the perfect place for ISO-DRAIN 8 M is in between the rock wall and the concrete inner shell - in tunnel renovation between the damaged and the new inner shell. In both installation situations ISO-DRAIN 8 M creates an intermediate layer and thus a cavity that allows strata and fissure water to be drained off. The plastic mesh ensures that the sprayed concrete adheres securely to the wall.
