What Trenchless Sewer Repair Involves in Raleigh, NC
Trenchless work trades the long ditch for one access point at the cleanout or a small pit in the yard. On a Raleigh house, a trenchless sewer line replacement or repair may combine several of the steps below, depending on what the footage shows:
- A camera run records every crack, root and low spot first, so the method is chosen from the pipe itself.
- Root and debris cutting clears the bore with a cutter head and leaves a clean wall for the liner to grip.
- Mechanical cleaning of the inside wall comes next, since an epoxy liner bonds only to a cleaned pipe.
- Sewer pipe lining feeds a resin-soaked fabric tube through the old pipe, then inflates a bladder that presses the tube against the wall while the resin cures.
- Pipe bursting pulls a bursting head through the old pipe, breaks it apart and draws new pipe in behind it.
- A single access point replaces the trench, which keeps shrubs, sod and concrete out of the repair.
- Sealed joints follow a liner, because the new inner wall closes the gaps roots used to enter.
- Permit questions are settled with the City before work begins, and we pull a permit whenever one applies.
