Cured-in-Place pipe liners

Unfortunately, over time many pipelines deteriorate. Pipelines made from steel and ductile iron are prone to corrosion and rust infiltration, which can cause leaks and sediment issues. Other types of pipes like vitrified clay, asbestos cement, and Orangeburg are all susceptible to cracking, leaking, and collapse.


US Trenchless of Sacramento and San Jose knows that the cost of repairing and replacing pipelines can be very expensive. That’s why we are pleased to offer our most exciting and innovative solution to date. With cured-in-place pipe (CIPP) lining, we are able to repair damaged pipes without disruption to your home or property. There is no damage to your floors, landscaping, driveway, or sidewalks, saving you tons of money, and avoiding the hassle of repairing damage left by traditional dig-and-replace methods.

The cured-in-place method itself isn’t new. It’s actually a technology championed by the British and perfected by American ingenuity. What makes US Trenchless cured-in-place liners different is that we offer a complete structural liner that, when installed, can be stronger than even cast iron pipe.

Cured-in-place lining is comparable to pipes like PVC and ABS, and is actually a resin-based epoxy that restores the strength and structural integrity of your existing pipeline and effectively resists future inflow and infiltration (I&I). Because we are also able to insert sectional liners that are from 2 to five feet long, you need not have the entire length of your pipeline lined. You can save money by lining only those sections of pipeline that are compromised. With US Trenchless’ cured-in-place lining, a bridge can be created between small sections of pipe that are missing, broken, or cracked, and will even eliminate future root intrusion.

Our Process 

First we locate the old pipe and conduct an inspection of the interior using a small camera attached to a long reel. The camera takes video that is displayed on a remote screen. This allows us to identify the condition of the pipe. Then, the pipe is cleaned of roots, buildup, and debris, and the liner is inserted. Once the liner is positioned, it is then hardened (cured).

When finished, the new inner pipe is from 3mil thick in residential sewer lines, up to 25mil thick in large diameter municipal pipelines. This new pipe liner is smoother than the old pipe was, and it resists buildup and root intrusion. It will not corrode or crack and the flow capacity of the pipe will be increased.

Our cured-in-place pipe lining technique works for pipes from 3 inches inside diameter, up 102 inches inside diameter and is compatible with:

  • Riveted Steel Pipelines
  • Ductile Iron Pipelines
  • Cast Iron Pipelines
  • Clay Pipelines
  • Asbestos Cement Pipelines
  • Threaded Steel Pipelines
  • Fuel Pipelines
  • Gas Pipelines
  • Sewer lines
  • Water lines
  • Storm Drain Lines
  • It also replaces RCP (Rapid Crack Propagation) Failed Fusible C900 Pipelines
