Pipe Bursting on O'ahu
Pipe bursting replaces your entire sewer line without trenching your yard. A bursting head fractures the old pipe outward while simultaneously pulling brand-new pipe into position. Full replacement — without the full excavation.

What We Do
When Pipe Bursting Is the Answer
Pipe bursting is the right tool when the line is too damaged for lining but you want to avoid a full dig.
Static Pipe Bursting
A hydraulic or cable-driven bursting head is pulled through the existing pipe, fracturing it into the surrounding soil while new HDPE pipe follows directly behind. The result: a completely new pipe in the same trench — with only entry and exit pits.
Root-Damaged Line Replacement
When root intrusion has severely damaged the pipe over its entire length, lining may not be viable. Pipe bursting replaces the whole run cleanly and permanently.
Collapsed Pipe Replacement
A collapsed sewer line can't be relined. Pipe bursting can still replace it in many cases — depending on the extent of collapse and soil conditions.
Corroded Cast Iron Replacement
Old cast iron sewer lines deteriorate from the inside and outside over time. Pipe bursting replaces the entire cast iron run with smooth HDPE that won't corrode.
Camera Inspection First
Every pipe bursting job starts with a video camera inspection to confirm the line is a candidate for bursting and to map the run from entry to exit point.
Post-Burst Camera Verification
After the new pipe is set, we camera inspect to confirm complete installation, smooth walls, and proper grade before restoring access points.
Common Questions
Frequently Asked Questions
How is pipe bursting different from pipe lining?
Pipe lining (CIPP) inserts a liner inside the existing pipe to create a new pipe within the old one. It works when the pipe is structurally intact enough to support the liner. Pipe bursting completely replaces the old pipe by fracturing it outward and pulling new pipe in. Bursting is used when the pipe is too deteriorated or collapsed for lining.
What size pipes can be burst?
Most residential sewer lines (4"–8" diameter) are well within the range of our pipe bursting equipment. We can also upsize during bursting — replacing a 4" line with a 6" line, for example — to improve flow capacity.
How long does a pipe bursting job take?
A typical residential sewer run (50–100 feet) is usually completed in one day. Longer commercial runs may take 2 days. The actual bursting process is fast — it's the setup, access pit excavation, and camera verification that account for most of the time.
What happens to the old pipe?
The old pipe is fractured into the surrounding soil during the burst. The fragments stay in place underground and gradually compact over time. There's no excavation required to remove the old pipe — it simply stays where it fell.
How long does the new pipe last?
HDPE pipe used in pipe bursting is rated for 100+ years. It's resistant to corrosion, root intrusion, and soil movement — significantly outlasting the cast iron, clay, or older plastic pipes it typically replaces.
