What Trenchless Sewer Repair Involves in Chapel Hill, NC
A trenchless job reaches the failed pipe through a cleanout or a small pit, leaving the long ditch out of the plan. For a Chapel Hill house, trenchless sewer line replacement or a lighter lining job may involve some of these steps, with the footage deciding which:
- A camera survey logs each crack, root mass and dip before anyone selects a method.
- Root removal with a cutting head leaves bare pipe wall for the liner to grip.
- Wall cleaning follows, because the epoxy resin bonds only to a pipe that has been cleaned.
- Sewer pipe lining inflates a resin-saturated sleeve against the host pipe, and once cured it forms a second pipe inside the first.
- Sewer pipe bursting cracks the old line outward while a head pulls new pipe in along the same path.
- A single access pit replaces the trench, so shrubs, pavers and sod stay in place.
- Sealed joints come as a side benefit of lining, since roots lose the gaps they used to enter.
- Permit and inspection steps are confirmed with the Town of Chapel Hill, and we apply for a permit if one is needed.
