What methods does B. Carlson use for sewer line replacement?

Question

Accepted Answer

We use three approaches — pipe lining, pipe bursting, and traditional open-trench replacement — and select based on what a camera inspection shows about pipe condition, route, and what is on the surface above the line.

Pipe Lining (CIPP)

A resin-saturated liner is drawn into the existing pipe and cured in place, creating a new seamless pipe inside the old one. It seals cracks and joint separations and eliminates the entry points roots use. Access is through small pits rather than a trench, so landscaping and paving stay intact.

Requires: a host pipe structurally sound enough to support the liner. Collapsed sections, severe sags, or badly deformed pipe rule it out.

Pipe Bursting

A bursting head is pulled through the old line, fracturing it outward while simultaneously drawing new HDPE pipe into place. This works where lining will not — including on collapsed lines — and can increase pipe diameter. It needs access pits at both ends and a route free of conflicting utilities.

Traditional Open Trench

Still the right answer in specific situations: when a line has a significant sag that needs re-grading (trenchless cannot correct slope), when the route will not accommodate access pits, when other utilities conflict, or when only a short section needs work and a targeted excavation is faster and cheaper than mobilizing trenchless equipment.

How We Choose

A camera inspection with locating comes first. It shows pipe material and condition, the exact nature and position of the damage, and whether the line is a trenchless candidate. We then present the viable options with prices side by side and let you decide. Our technicians are not paid on commission, so if a spot repair solves the problem, that is what we recommend.

Cost Comparison Worth Understanding

Trenchless often looks more expensive on the line item and comes out comparable or cheaper once concrete replacement and landscape restoration are counted — particularly on properties with driveways, mature trees, or established xeriscaping over the line.
