Types of Pipe Lining and What You Need to Know
A plumbing repair does not always have to mean a long, messy excavation. Trenchless methods can restore damaged residential and commercial piping with much less disruption. Understanding the available approaches can help you make a better decision for your property.
Four Pipe-Rehabilitation Methods
- Cured-in-place pipe (CIPP): A widely used method that forms a resin liner inside an existing pipe.
- Pull-in-place lining: A liner is pulled into position between access points before it is cured.
- Pipe bursting: The damaged pipe is broken apart while a replacement pipe is pulled into its place.
- Epoxy coating: A protective coating is applied to the interior surface of an existing pipe.
What Is CIPP?
CIPP uses a flexible textile liner saturated with liquid resin. The liner is inserted into a damaged pipe and cured in place, creating a smooth, seamless surface that seals cracks and leaks. Liners can be prepared to match the size and shape of many existing pipes.
What Does Trenchless Mean?
Conventional sewer repair may require a trench along the damaged line. A trenchless approach uses one or more smaller access points and a sewer camera to inspect the pipe, locate damage, and identify roots or other obstructions without excavating the entire route.
Benefits of CIPP Trenchless Repairs
Large excavations can interrupt water and sewer service, damage landscaping and hardscaping, and create safety concerns around a property. When the existing pipe is a good candidate, CIPP can reduce that disruption considerably.
- It can rehabilitate many pipe materials, including concrete, PVC, clay, and cast iron.
- A properly specified and installed liner is strong and designed for a long service life.
- Many projects can be completed much faster than traditional excavation.
- The continuous liner can seal cracks, broken areas, and leaking joints.
- Reduced excavation can make CIPP more economical than traditional replacement.
Rossman Plumbing can use camera inspection and professional evaluation to determine whether a small section or a longer run of sewer pipe is suitable for lining. Prompt assessment helps prevent leaks and pipe damage from becoming larger problems.
