Pipe Lining vs. Pipe Bursting: Which Trenchless Method Is Right for You?

Trenchless isn't one method — it's two, and choosing wrong wastes money. Here's how lining and bursting actually compare.

Pipe lining (CIPP): a new pipe inside the old one

A resin-saturated liner is inverted into the existing pipe and cured rock-hard, creating a seamless structural pipe within the old one. Best for: cracked clay or cast iron that still holds its shape, root intrusion at joints, minor offsets, and lines under expensive hardscaping. Cost: roughly $80–$250 per foot. Lifespan: 50+ years.

Pipe bursting: a new pipe in the old one's place

A bursting head fractures the old pipe outward while pulling new HDPE pipe through the same path. Best for: collapsed sections, severe offsets, undersized lines worth upsizing, and badly deteriorated pipe. Cost: roughly $60–$200 per foot. Lifespan: 50–100 years.

Head-to-head

• Excavation: lining needs the least (often just existing access); bursting needs entry and exit pits.
• Diameter: lining slightly reduces internal diameter; bursting can increase it.
• Collapsed pipe: lining can't fix it; bursting can.
• Bellies (sags): neither fixes a sag properly — bellies need excavation and re-grading.
• Speed: both typically finish in one day for residential runs.

When neither works

Severe bellies, extreme utility congestion, or no viable access points can rule out both methods. That's when careful open-trench replacement is the honest recommendation — and a contractor who only owns trenchless equipment may not tell you that.

How to decide

The camera footage decides — it's that simple. Get an inspection, look at the video with the technician, and choose the method that matches your pipe's actual condition. Questions? Call (833) 713-2101.
