The Challenge

A Clay Sewer Lateral at the End of Its Life

Like thousands of Metro Detroit homes of its era, this Sterling Heights house was built with a vitrified clay sewer lateral — and clay pipe fails in a predictable way. Joints shift and separate, hairline cracks spread, and tree roots find every gap. This line had deteriorated past the point where spot repairs made sense: fix one section, and the next fails a season later.

A sewer camera inspection confirmed the diagnosis — the clay was deteriorating along its run, not at one convenient spot. That ruled out a patch and left two real options: dig the lateral up, or reline it from the inside.

Digging meant an excavator on the property, days of disruption, and a restoration bill for everything sitting above the pipe. Bison recommended the second option.

Deteriorating Clay Pipe

Vitrified clay laterals crack, shift at the joints, and invite root intrusion as they age — and this one was failing along its run, not at one convenient spot.

Excavation Was the Wrong Answer

A traditional dig-and-replace would tear open the property to reach the lateral — days of disruption and a restoration bill on top of the plumbing work.

The Clock Was Ticking

A failing lateral doesn't heal. Left alone, deterioration ends in a collapsed pipe — turning a plannable repair into an emergency excavation.

The Solution

A New Pipe, Cured Inside the Old One — No Trench Required

Instead of digging, Bison relined the pipe from the inside. A resin-saturated liner was installed through the existing clay lateral and cured in place, forming a smooth, jointless new pipe within the old one. The entire repair ran through a single interior access point — the yard, driveway, and landscaping were never touched.

Clean & Prep

The line is thoroughly cleaned and cleared so the new liner bonds to sound pipe, not debris.

Camera Verification

A sewer camera confirms the pipe's condition and measures the run before the liner is cut and saturated.

Liner Installation

The resin-saturated liner is driven through the line under controlled pressure from the inversion drum — no trench, no torn-up yard.

Cure & Final Pass

The liner hardens in place into a rigid new pipe, and a final camera pass verifies the finished result.

Why No-Dig Wins

Everything the Homeowner Kept

CIPP lining restores the pipe — and leaves everything above it exactly as it was.

0 ft

of yard trenched. No excavator on the lawn, no spoil pile, no settlement risk.

1 pipe

continuous and jointless — no seams for roots to find their way back into.

100%

of the yard, driveway, and landscaping left untouched.

1 access

point — the entire repair ran through a single interior opening instead of an open trench.
