What is Pipe Lining?

Pipe Lining is a  minimally invasive process which allows the rehabilitation of existing drainage pipe without having to tear it out and replace it conventionally. In short, Pipe Lining is accomplished by inserting an epoxy saturated felt tube into the pipe, inflating it and letting it cure in place.  After the liner has cured, the result is a brand-new pipe within the old pipe. This new inner-pipe has a 50 year life use expectancy!

The Pipe Lining Process Explained


    First, an initial inspection of the pipe is performed by means of a high definition, full-color, and self-leveling sewer camera. During this process we will measure the linear footage and diameter of your pipes as well as locate and document any problems such as cracks, blockages, tree roots, etc. After the inspection, you are provided with a copy of the video, a not-to-scale drawing of your sewer’s layout, a deficiency report and a proposal to remedy any pipe problems we may have discovered.


    Second, the pipes are thoroughly cleaned utilizing hydro-jetting or mechanical methods. This process removes tree roots, blockages and scale buildup in preparation for lining. On occasion, sewer cleaning may be all that is required to remedy pipe problems such as slow drains and blockages.


    After the pipe is cleaned and excess debris is removed, the pipe can now be lined. The felt liner is measured and cut to the dimensions of the pipe such as length and diameter. Then the liner is saturated with a two-part epoxy and inserted into the pipe either by the Inversion Method or the Pull-In-Place Method. An inflatable bladder is inflated inside of the epoxy-saturated liner causing the liner to take the shape of the pipe while it cures in place. After the epoxy has cured, the bladder is removed and a brand new pipe is left in place inside of the existing one.


    Finally, after the pipe has been lined, the branch lines that were covered over will have to be robotically reinstated or reopened with our state of the art reinstatement equipment. Robotic reinstatement technology allows us to use one continuous liner from one end of the pipe to the other ensuring that the fittings are protected as well.

Installation Methods


(With Robotic Branch Reinstatements)

Typical Uses

The continuous inversion method of pipe lining can be utilized to install liners in both horizontal and vertical pipes. Continuous Inversion is the only manufacturer approved method to line vertical stacks.

Required Access

Only one access point is required to install the liner such as a cleanout or a roof-vent opening.

Epoxy Adhesion

Due to the inversion of the liner, the epoxy cures on the outside of the liner – adhering to the host pipe. This epoxy-adhesion, as well as other features of Continuous Inversion, prevents slippage in a vertical stack.


If there are too many offsets in a vertical stack, additional access points may need to be created.


The entire length of pipe, including fittings, are protected. Epoxy adheres to the host-pipe – securing the liner in place.


(Also Known as P.I.P.)

Typical Uses

The Pull-In-Place (P.I.P.) method is utilized to install liners in horizontal lines only.

Required Access

Two access points are required to install the liner, one to feed the liner into the pipe, the other to pull the liner in place such as one cleanout opening on each side of a house. In some cases, a P.I.P. liner may be fed down a vent stack and pulled into the corresponding branch line.

Epoxy Adhesion

The Pull-In-Place liner DOES NOT adhere to the host pipe since the epoxy cures on the inside of the liner. This is acceptable in a horizontal line as the structural liner is not at risk of slipping. However, epoxy adhesion is very important in a vertical stack application.


Not practical for vertical stacks.


Quick set-up time and less equipment is required for installation.

How much does sewer pipe lining cost?

In most cases, our sewer pipe lining costs are 30-40% less expensive than conventional dig, demolition, and replace repair methods. In all cases, the pipelining process is less intrusive and faster than conventional repair methods. A physical inspection is required in order to ascertain, for example, the number of plumbing fixtures, the layout and design of the piping system, and the type of pipe material experiencing problems.

If my pipes are old and fragile, can pipe lining restore them?

YES! Most pipe systems only require 20% of their integrity to begin the trenchless pipe lining process. If drainage pipes have not completely collapsed, in most cases, we can rehabilitate the pipe back to a functional drainage line. A pipe lining specialist will perform a full on-site inspection to first assess the condition of the piping system, the nature of the problem, and advise you as to the best method of restoration.

What types of pipe can pipe lining restore?

Pipe lining can restore cast iron, clay, PVC, plastic, and concrete. Pipe lining is not a solution for orangeburg pipe.

Does pipe lining last longer than new pipe?

YES! Metal pipes begin to deteriorate the moment they are put into service and water runs through them. PTI lined pipes won’t corrode and are resistant to deposits from water by-products, as these cannot adhere to the interior walls of epoxy lined pipes. Our lining material has a 50 year life expectancy with a 5 year parts and labor warranty on our installations.

Will I save money by choosing trenchless pipe repair?

YES! Owners will save thousands of dollars by lining the existing piping system from inside the walls instead of replacing the entire plumbing system. No digging into floors or destruction of walls means no reconstruction costs, and means tenants don’t have to stay in hotels at the owner’s expense, or be inconvenienced for weeks or months during a re-pipe. The average PTI process takes about 3 days. Also, in many re-pipe situations the property owner is required by law to bring the piping, walls and surrounding areas up to the current building and fire codes during the re-piping process. This is NOT NECESSARY with the PTI lining process because we are only working on the interior of the piping system and do not disturb surrounding areas.

Why should I line my pipes instead of re-piping them?

Consider the additional costs associated with traditional re-piping: tearing into walls; living away from home for weeks or months; hiring the right contractors and plumbers; reconstruction with associated cost and mess; unforeseen price increases, and accidental property damage. In many re-pipe situations the property owner is required by law to bring the piping, walls and surrounding areas up to the current building and fire codes during the re-piping process. This is NOT NECESSARY with the PTI lining process because we are only working on the interior of the piping system and do not disturb surrounding areas.
