Note: Lining is cheaper per foot than bursting, but bursting is cheaper than a full excavation if you have a long driveway. Yes, with one warning. Trenchless pipe bursting is objectively superior to digging for most clay pipe failures. It is faster, cheaper, and leaves your patio and roses intact.
The old solution was horrific: rent a jackhammer, tear up your driveway, destroy your landscaping, and dig a 6-foot-deep trench through your yard. The new solution?
However, clay is also brittle. Over 50–100 years, roots invade the joints, the pipes crack from ground shifting, and the bottom half of the pipe often erodes away.
The crew digs a "launch pit" near your house foundation and a "receiving pit" near the property line or city tap. This is minimal disruption compared to a full trench.
