What is Pipe Lining?
Once pipes start showing wear or signs of damage, you might think its time to break the bank. Luckily, there is a possibility for a more cost-effective solution. Pipe lining allows a skilled plumber to restore a damaged pipe with little excavation work.
Benefits of Pipe Lining:
Save money & time on excavation work
Prevents future tree root intrusion
Repairs cracked or damaged pipes

How Pipe Lining Works
1. Video Camera Inspection
We perform a video camera inspection to detect signs of root intrusion, offset pipes, blockage and other sources of damaged pipes.
2. Pipe Line Cleaning
After we perform the video camera inspection, we start to clear out the debris. In order to get successful and quality results, the line must be clean.
3. Pipe Lining
Once the pipes have been cleared, we insert an epoxy-based liner and is inflated to get an even lining in the line. After the liner is set into place. It has to cure.
4. Final Inspection
After the lining has been cured, the bladder used to inflate the liner is removed. Now it is time for the final video camera inspection. Now your restored pipes could last for another 50 years.
Frequently Asked Questions
We have the technology to restore Sewer, Drain and Storm systems both horizontal and vertical with diameters from 2″ to 8″.
In most situations yes. That is one of the biggest savings that pipelining can provide, saving your driveway, sidewalk, and yard from being broken up and needing to be replaced or repaired. It can also often prevent you from needing to dig up city sidewalks and streets which can be complicated and expensive.
It typically takes from 1.5 – 5 hours for the CIPP line to cure and harden, depending on the formulation of the epoxy resin used and the method for “Curing” the pipe.
Cured in Place Pipe (CIPP) restoration only requires the current pipe as a “mold” to install the new pipe inside the existing one. Once the new CIPP line is installed, the “host” pipe is no longer needed. The new CIPP line will meet or exceeds all the ASTM standards required for pipe replacement. The only real advantage of traditional pipe replacement is when the existing line is not a candidate for CIPP restoration. The older means of pipe replacement where a plumber will dig down to replace the existing pipe requires the demolition of whatever is above the existing line. If there are major offsets or bellies (typically over 25%) or a collapsed pipe, CIPP will most likely not be a candidate for CIPP restoration.
There are several options available to us to install a cured in place pipe (CIPP). Most of them do not significantly change the end result, only the method of installing it. The two most common CIPP methods are “inversion” and “pulled in place”. Inversion lining only requires one access point close to where the new liner will be installed. This is performed using an epoxy saturated felt tube to be “inverted” or turned inside out directly into the host pipe. After which an inflatable bladder is also inverted into the felt tube. Once the epoxy has hardened, the bladder is un-inverted and removed, leaving the new pipe in place. The Pulled in place method requires two access points but has the advantage of allowing those access points to be over 100ft from the pipe to be restored if necessary. With the pulled in place method, a similar epoxy saturated felt tube and bladder is pulled into place with a small cable and the bladder on the inside is inflated. Once the epoxy liner has hardened, the bladder is deflated and removed.
It is usually best to avoid using your drains while the liner is being installed.
CIPP lining is a subset of a larger family of technologies that make up Trenchless Pipe Restoration. Options like Pipe Bursting and Pipe Coating are also available when CIPP lining is not the best option. Pipe Bursting requires the excavation of both ends of the pipe and Pipe Coating does not create a new structural pipe, but does stop the corrosion and erosion of the existing line. Like most answers, it depends on the situation. There are also a variety of older technologies in the “Trenchless” world that still exist, but they have neither economic or end-result advantages and have simply fallen by the wayside.
All trenchless pipelining installers should be certified, but just because someone has the equipment and materials does not mean that they are. Always make certain that you are working with a certified and insured installer.
It’s a two-part epoxy. There is a base and catalyst, once mixed it activates the epoxy and begins curing (hardening).
We can line clay, cast iron, ABS, PVC, Concrete and sometimes Orangeburg.
There isn’t one technique better or worse than the other. The right trenchless method for your property is usually determined after a professional can make an onsite evaluation.
