Repair and rehabilitate damaged sewer pipes with Repiper’s CIPP sewer lining method. The process creates a new, durable lining inside the existing pipe, reducing the need for extensive excavation, demolition and traditional sewer pipe replacement.
OVERVIEW
Cured-In-Place-Pipe (CIPP) sewer lining is a method of trenchless rehabilitation and restoration of existing main, lateral, and vertical sewer and drain pipes. The process involves lining pre-existing pipe systems in need of repair or rehabilitation with tight-fitting, jointless, and corrosion-resistant replacement pipes and its fittings made of cured epoxy.
As many other industries, the relining industry has several names for the same thing. Sometimes it is difficult to work out what is what and if there is any generic difference between the techniques. Basically, CIPP sewer lining, trenchless sewer lining, and trenchless pipe lining all refer to the same thing. These are the most common names for installing a new structural pipe material inside an original pipe without having to tear down walls, dig, or excavate around the pipe.
COMPARISON
Repiping is the more traditional route to restore the function of a sewer pipe system – by replacing the old pipes with new ones. It is slowly but surely being replaced by the CIPP sewer lining method. And with good reason. It grants a host of advantages not only for the installers, but also for the end-customers whose pipes are being replaced.
Relining is less invasive, with a less destructive process, where the owner of the facility does not have to stay elsewhere or stop their operations until the work is completed. It is cheaper as the cost for the relining is significantly cheaper than the combined cost of repiping which includes buying the new pipes and the cost of remediation (repairing walls, floors, and other structures as well as repainting). CIPP Relining usually takes a few hours up to a few days at maximum – depending on the size of the pipe system – while repiping can take weeks to finish. Ultimately, it depends on the extent of the job and the amount of demolition required.
HOW IT WORKS
Trenchless commercial sewer line repair is performed in four steps:
Above ground, it is important to install the new liners in the flow of water, overlapping. This is to prevent the risk of sewer or drain water getting behind the new lining material over time. This way we can optimize the lifetime of the new CIPP system inside without seal-failure due to poor adherence, which is always a risk when working in old pipes.
METHOD
Repiper provides a complete solution for residential, industrial, and commercial small dimension sewer repair, offering both the necessary tools and products, and an innovative StepbyStep method. The entire process only takes a few days and is carried out at a fraction of the cost of traditional methods.
ADVANTAGES
Traditional sewer pipe repair can require excavation, demolition and reconstruction, creating disruption for building occupants and surrounding operations.
Repiper’s StepbyStep CIPP sewer lining method repairs suitable pipes internally and provides several practical advantages.

What types of sewer pipe damage can CIPP lining repair?
CIPP lining may be suitable for cracks, leaking joints, corrosion, small holes and deteriorated internal surfaces. A camera inspection is required to confirm that the existing sewer pipe retains sufficient stability for relining.
Can CIPP sewer pipe lining be installed without excavation?
In many cases, CIPP sewer pipe lining can be completed without excavating the full pipe route. The liner is installed through existing or locally created access points, although limited access work may still be required.
How long does a CIPP sewer lining installation take?
Installation time depends on the pipe length, diameter, condition, configuration, accessibility and curing method. CIPP lining can often be completed faster than conventional replacement because extensive excavation and reconstruction are reduced.
How is a completed CIPP sewer line inspected?
A camera inspection is normally carried out after the liner has cured. The inspection checks that the lining is correctly positioned, fully open and free from visible installation defects.
