Cast Iron Sewer Replacement in Knoxville, TN
When cast iron is too thin or broken to line, trenchless replacement puts in modern pipe.
- DiggingAs little as possible
- MethodMatched to the fault
- ResultA fix built to last
Cast iron can last a long time, but not indefinitely; corrosion eventually thins the walls and breaks the pipe. When lining is not suitable, because the pipe has holes, sections are missing or the host is too weak, replacement is the answer. Trenchless replacement pulls in new pipe through or alongside the old without excavating the whole run.
We camera and locate the iron pipe, assess its remaining wall, and plan pipe splitting or a related method suited to cast iron. Under-slab or tight runs may use tunneling or limited access. We explain the options honestly and give a written estimate.
