Project Overview
An underground leak had washed soil away beneath an existing slab. Clendaniel Contracting’s crew exposed the damaged piping and worked through an unexpected connection beneath the adjacent sidewalk.
As excavation continued, the crew uncovered an unfamiliar coupling and a short section of existing pipe. Rather than assuming the connection was a standard bell end, they removed the exposed section for a closer look and consulted the supply house before continuing the repair.
Working Through Existing Conditions
The crew traced the connection back to ductile-iron pipe and installed new piping. The work also included protective wrapping around the new metal pipe and a concrete support behind the 90-degree bend.
Accessing the connection from the excavation allowed the crew to work beneath the sidewalk without removing it at that stage of the repair.
Project Highlights
- Exposed damaged underground piping and investigated an unexpected existing connection.
- Installed new ductile-iron piping with protective wrapping.
- Placed concrete support behind a change in direction.
- Filled the void beneath the slab with slurry and backfilled the exterior excavation.
Slurry Placement and Backfill
To complete the work, the crew cut an access opening and placed slurry beneath the building slab to fill the void left by the washout. They filled the excavation around the repair and backfilled the work area.
