Replacing Clay Sewer Pipe — Without Digging
Replacing clay sewer pipes without digging, also known as trenchless sewer replacement, is a minimally invasive method that allows for the renewal of sewer lines without extensive excavation. This technique is particularly useful in areas where digging is not feasible or would cause significant disruption, such as in urban environments, under roads, or in landscaped areas.
Do not let a plumber put a CIPP liner into a clay pipe that has collapsed joints or missing chunks. The liner needs a rigid tube to press against. If the clay bottom is missing, the liner will just push into the dirt and fail. Always ask: "Is my pipe a candidate for lining, or do we need bursting?" replacing clay sewer pipe without digging

Hydro-jetting is used to clear out roots, grease, and debris so the new liner or bursting head can pass through.
Two small access points are created (usually at the house and the street) to pull the equipment through.
A second camera pass ensures the new line is smooth and properly connected.
