Sewer Repair – 150mm Sewer Collapse and Patch Repair
Client’s brief
Remove a sewer collapse on a 150mm sewer 6 meters deep as it could not be excavated as under a retaining wall.
Site difficulties
Depth of the sewer in the highway and its close proximity to a large retaining wall.
Solution
Employ specialist cutting solutions to carefully remove the broken pipework and debris and clean away the pipework and silt, then install a specialist patch that wouldn’t over expand and cause the pipework to fail further.
