What Is Pipe Bursting?
What Is Pipe Bursting?
Pipe bursting is a trenchless pipe-replacement method in which a hydraulically or pneumatically driven bursting head is pulled through an existing pipe by a cable winch from a receiving pit. The bursting head fractures (bursts) the old pipe outward into the surrounding soil while simultaneously pulling a new high-density polyethylene (HDPE) pipe into the same cavity. The end result is a brand-new full-diameter pipe in the footprint of the failed pipe — with zero trenching along the pipe run, only two small access pits (one at each end).
The method is governed by ASTM F1962 and standardised by NASSCO. It is distinct from CIPP pipe lining: bursting REPLACES the pipe entirely and allows upsizing (for example 3-inch to 4-inch); lining RESTORES the existing pipe wall only. Wooley operates Pow-R Mole pipe-bursting equipment — the client-confirmed manufacturer relationship that trains and certifies our crews — and fuses HDPE pipe on-site with an in-house hydraulic fusion welder rather than sub-contracting.

Our 9-Step Pipe Bursting Process
When you choose Wooley for this work, every job follows the same documented process — start to finish.
-
1
Camera scope
Confirm bursting-candidate status (full collapse, Orangeburg, cast iron rust-through, upsizing need)
-
2
Excavate two small pits
Insertion pit at the cleanout / main side, receiving pit at the building side
-
3
Set the bursting head + pulling cable
Thread the winch cable through the existing pipe
-
4
Fuse HDPE pipe on-site
Hydraulic fusion welder joins lengths into a single continuous new pipe — in-house, never sub-contracted
-
5
Connect HDPE behind the bursting head
Tow-cable locked to the fused HDPE run
-
6
Pull the bursting head through
Pneumatic or hydraulic power fractures the old pipe outward, pulls HDPE into position
-

Pit fill + landscape touch-up; most residential bursting completes in a single working day
When to Call for Pipe Bursting
Pipe bursting is triggered the moment the camera scope reveals a condition outside the lining envelope: Orangeburg in any state; clay with multiple collapses; cast iron with rust-through perforations; pipe with a belly or sag so severe that a liner will not restore flow; or any lateral needing upsizing. The Annehurst Village / Huber Village belt in Westerville (1960s–70s Orangeburg subdivision) and the older 1970s Gahanna sections are the highest-incidence bursting markets in our coverage area — we've replaced hundreds of collapsed Orangeburg laterals under mature tree canopies without disturbing the surface landscape. Seasonal pattern: early spring freeze-thaw and heavy rain events often push a borderline Orangeburg lateral into full collapse. If your pre-sale scope in Westerville showed Orangeburg and you're closing in the next 60 days, bursting is the path.
What Happens If You Defer the Bursting
Deferred bursting on a fully collapsed lateral means no sewer service at all — the property becomes functionally uninhabitable until repair. The alternative to bursting in these scenarios is traditional open-cut, which destroys the landscaping, driveway, or road surface above the pipe; restoration costs often add $5,000–$25,000 on top of the pipe work. Orangeburg pipe left in place WILL fail — it is a known terminal-lifespan material, and any 1950s–60s Central Ohio lateral on Orangeburg is already past its 50-year design life. Deferral on a known Orangeburg lateral is just setting a countdown to an emergency backup.
What Pipe Bursting Costs in Columbus
What does standard residential lateral (clay / cast iron) run?
$150 – $250 / ft for the 40–60 ft lateral, 4-inch replacement. Typical full-line job: $8,000 – $15,000.
What does orangeburg replacement run?
$165 – $275 / ft for the premium reflects added excavation care. Typical full-line job: $8,500 – $15,500.
What does upsizing (3→4 or 4→6 inch) run?
$175 – $300 / ft for the new pipe diameter larger than original. Typical full-line job: $9,000 – $16,000.

What Is Pipe Bursting? — Frequently Asked Questions
A hydraulic or pneumatic bursting head is pulled through your existing pipe by a cable winch from a receiving pit. The head fractures the old pipe outward into the surrounding soil while simultaneously pulling a new HDPE pipe into position behind it. The end result is a brand-new full-diameter pipe in the exact footprint of the old one — with no trenching along the pipe run, only two small access pits (one at each end).
Usually yes — once restoration costs are factored in. Pipe bursting runs $150–$300 per linear foot in Columbus, with most residential laterals totalling $8,000–$15,000. Traditional open-cut replacement has a lower raw pipe-work price ($3,000–$15,000), but the yard / driveway / hardscape restoration typically adds $5,000–$25,000 — usually doubling the true final bill. Bursting preserves the surface, so there's no restoration to pay for.
Yes. The method works for both sewer and water service lines — the HDPE pipe used in water applications is NSF-61 rated for potable water. Water-line bursting is a common upgrade for homes with galvanized steel or old copper service lines that are reaching end of life. Pricing runs $150–$275 per linear foot, typically $6,000–$14,000 for a residential water service replacement.
Most residential bursting jobs complete in a single working day — usually 6 to 10 hours on-site including pit excavation, fusion of the HDPE run, the bursting pull itself, transition connections at both ends, camera verification, and pit restoration. Commercial jobs may span two days depending on length and complexity.
When done correctly, no. Our pre-work includes utility locates (Ohio 811) to map gas, water, electric, and communication lines in the pulling corridor. The bursting head fractures the old pipe outward within a confined cavity; nearby parallel utilities at safe offsets (6+ inches) are not affected. Where utility clearances are tight, we switch methods — spot repair, open-cut for a short segment, or a re-routed bursting path.
Yes — bursting is the REQUIRED method for Orangeburg. The tar-impregnated fibre wall of Orangeburg pipe cannot be CIPP-lined (the liner cure pressure would fail), and the material will eventually fully collapse regardless of what you do. Bursting replaces the Orangeburg with a new HDPE pipe in the same footprint. Central Ohio's 1950s–60s housing stock has heavy Orangeburg exposure — particularly Westerville's Annehurst Village and similar subdivisions.
