Clay Tile Sewer Pipes in Nashville and Middle Tennessee
Pipe or method

Clay Tile Sewer Pipes

Rock-hard and long-lived, but the short sections and joints let roots in. Common in older sewer laterals.

Vitrified clay is extremely durable chemically, which is why clay sewer lines from decades ago are still working. The weakness is the joints: short two- to three-foot sections with bell-and-spigot connections that open slightly with soil movement, letting roots in.

Clay can also crack from heavy loads or settlement. Camera inspection shows the joints and cracks. Cleaning and cutting clear the roots, and lining or replacement closes the pipe for good, depending on what the camera reveals.
