Going Trenchless: A Brief Comparative Guide on Pipe Lining and Pipe Bursting

When underground pipes fail, homeowners often worry about the mess and cost of digging up their yard. Thankfully, trenchless technology makes repairs easier, cleaner, and more convenient. Two of the most popular methods of trenchless sewer repair in San Carlos, CA are pipe lining and pipe bursting. Bell Plumbing is here to help you understand the difference and decide which option might be best for your situation.

What is Pipe Lining?

Trenchless pipe lining, also called CIPP (cured-in-place pipe) lining, involves inserting a flexible liner coated with resin into the damaged pipe. Once in place, the liner is inflated so it sticks to the inner walls. The resin hardens, creating a new, seamless pipe within the old one. Pipe lining works well for pipes with cracks or minor corrosion, but no major collapse. It can extend the pipe’s life without major excavation.

What is Pipe Bursting?

Pipe bursting is different. This trenchless pipe replacement method breaks apart the old pipe while pulling a new one (usually made of HDPE) into its place. A bursting head is pushed through the existing pipe, shattering it outward. As the old pipe breaks, the new pipe slides in behind it. Pipe bursting is ideal when the existing pipe is too damaged for lining or needs a full replacement. It also allows for a larger diameter replacement pipe if needed.

Which Method Should You Choose?

Choosing between pipe lining and pipe bursting depends on the pipe’s condition, the material, and the goal of the repair. If the pipe is mostly intact but leaking or corroded, lining may be enough. If the pipe has collapsed sections or needs upsizing, trenchless sewer replacement is usually better.
