The steel bursting head is attached to the rod at the receiving pit. The new HDPE pipe is attached behind the bursting head.
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.
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?
If your home was built before 1970, there is a good chance your main sewer line is made of vitrified clay (VCP). For decades, clay was the gold standard. It was inert, cheap, and resistant to chemical corrosion.
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.
