Indepth were asked to carry out an emergency dig down and temporary repair to a 600mm diameter pipe which had collapsed. There was a watercourse parallel to the works and a water park lake within 500m.
Indepth excavated to a depth of approximately 5m and carried out the repair using a 600mm diameter plastic pipe and connected onto the existing concrete pipe once we had found a suitable joint using a band seal system. The pipe was then surrounded in concrete for protection and the excavation backfilled and reinstated.

The project consisted of the following elements:
