What is CIPP pipe lining?

CIPP (Cured-In-Place Pipe) lining is a trenchless rehabilitation method that creates a new pipe inside the existing host pipe to restore structural integrity and stop leaks.

When is CIPP a good choice?

CIPP is commonly used when pipes have cracks, corrosion, infiltration, or joint issues and you want to avoid excavation and surface restoration.

Do you offer multiple lining methods?

Yes. TrenchFree supports multiple CIPP approaches, including inversion, pull-in-place, brush-on, and spray-on liner methods, depending on the project requirements.

Cured-In-Place Pipe (CIPP)

Trenchless Pipe Rehabilitation for Sewer, Storm and Utility Systems

TrenchFree provides full-length Cured-In-Place Pipe (CIPP) rehabilitation to restore aging or damaged pipelines without excavation. CIPP creates a new, structurally sound pipe inside the existing host pipe—eliminating cracks, leaks, corrosion, and infiltration while extending service life for 50 years or more.

Our team matches the right CIPP method to your pipe diameter, material, access conditions, and performance requirements. Whether you’re managing a municipal sewer system, commercial property, or industrial facility, we deliver lasting results with minimal disruption.

How CIPP Works

A flexible, resin-saturated liner is inserted into the damaged pipe, positioned precisely, then cured in place using heat, UV light, or ambient conditions. Once hardened, the liner forms a seamless, jointless pipe-within-a-pipe that restores full flow capacity and structural integrity.

CIPP Methods

Inversion lining — Liner is inverted into the pipe using air or water pressure, ideal for longer runs
Pull-in-place lining — Liner is pulled through the pipe and inflated, suited for precise positioning
Brush-on liner systems — Resin is applied directly to the pipe wall for smaller-diameter applications
Spray-on liner systems — Structural coating applied via rotating spray head
