Pipe Bursting in Farmers Branch

What fails under Farmers Branch homes

Across the Plains and Texas, older neighborhoods have clay and cast iron laterals, and a surprising amount of Orangeburg pipe went in during the postwar building boom. Slab foundations are common in the south of the region, with cast iron drain lines underneath them.

Expansive clay soils that swell when wet and shrink hard in drought are the main enemy of sewer pipe here; they open joints, create bellies, and crack cast iron. Hot summers drive tree roots deep toward the moisture in a sewer line.

Trenchless methods restore the line without opening a slab or a yard that will move again next season, and a bursted line in new HDPE tolerates soil movement far better than jointed clay.

How pipe bursting works

A steel cable is threaded through the old sewer line from a pit at one end to a pit at the other. A cone-shaped bursting head, with new high-density polyethylene pipe fused to it, is pulled through by a hydraulic unit. The head splits the old clay or cast iron outward into the soil and the new pipe follows in the same alignment at the same depth. The result is a single fused length of pipe with no joints for roots to find.

When bursting is the right call

• Collapsed sections — a liner needs a host pipe to hold its shape; a collapsed run has none.
• Bellies — a low spot that holds water stays a low spot after lining. Bursting lays new pipe on a fresh bed.
• Undersized lines — bursting can upsize a 3-inch lateral to 4 inches; lining slightly reduces diameter.
• Badly deformed pipe — Orangeburg that has flattened, or cast iron with most of its bottom gone.

What the job looks like

One pit at the house or cleanout, one at the property line or the street connection, each a few feet square. Utilities that cross within a foot or two of the sewer path are located and potholed first. The pull takes an hour or two; the whole job, including fusing, connections, inspection and backfill, is usually one day.

Permits and the street

If the downstream pit is in the sidewalk, parkway or street, a right-of-way permit and restoration to city standards are required in addition to the plumbing permit. If the connection at the main is replaced, the city inspects it before the pit closes. Confirm who is handling this before work starts.

Getting it done in Farmers Branch

A camera inspection maps the line and marks every defect on the ground with its depth. The line is cleaned with a hydro jetter so the pipe wall can be seen and, if it is being lined, so the resin bonds to clean pipe. Lining works from the cleanout at the house; bursting needs a small pit at each end of the run. Either way the yard, driveway and slab in between are never opened. Most residential jobs in Farmers Branch finish in a day, and you should receive the before-and-after footage as part of the job.

Permits are part of it. Lateral work in Farmers Branch normally needs a plumbing permit, and anything in the sidewalk, parkway or street needs a right-of-way permit as well. The contractor pulls those and schedules the inspection; if a quote does not mention them, ask.
