Underground & Vertical Sewer & Rain Drain Pipe Lining
Do Your Sewer Pipes Need To Be Re-Lined?
Are you experiencing frequent sewage backups? Do you have to repeatedly pay the drain rooter company to unclog your drains? If so, you most likely have tree roots growing in your sewer pipe that grow back after the rooter company leaves.
Are Your Vertical Rain Drains – Sewer Stacks Leaking?
After about 30 years vertical cast iron sewer pipes and rain drains in high rise condominiums will have rusted enough to get longitudinal cracks. The option of excavating the walls to replace these pipes is very inconvenient, messy, expensive and time consuming.
The only permanent way to solve the problem is to replace the broken or cracked sewer pipe, or to install a new physical inner pipe lining. No matter whether you have cast iron sewer pipes that are cracked or have missing pipe floors or clay sewer pipes with entire sections missing, sewer pipe lining is designed to form a new durable inner pipe.

So What Exactly Is Sewer Pipe Lining?
The new inner pipe lining is a long special fabric tube that has been wet out or saturated with a resin that hardens by itself within 2-4 hours. The new inner pipe only reduces the pipe diameter by about 5%, so flow is not affected, and the pipe lining material has a 100-year engineered life and typically comes with a 50 year warranty.
How Is Sewer Pipe Lining Installed?
First the sewer pipe is cleaned with a high pressure water jetter that removes all roots and sludge and a sewer pipe video inspection is made to determine the length of pipe that has to be relined. Then a long special fabric tube is cut to the correct length and the self hardening part A and part B epoxy resins are mixed and used to completely saturate the fabric tube.
The fabric tube is then either pulled into the broken pipe or air pressure is used to shoot the liner into the pipe (see video below). Then the fabric tube is inflated with air for 2-4 hours while the resin hardens.
After the new liner is fully cured, a final pipe video inspection is made for quality control.
How Strong Is The New Inner Pipe?
The final new inner pipe is designed for load-bearing pipes that are located under roads, railways and building footers. If, for example, a section of clay or cast iron sewer pipe is missing, the new inner lining is designed to be a stand-alone pipe. The video on the right side of this page (VIOLENTLY) demonstrates the strength of sewer pipe lining – check it out.
Pipe lining is the modern alternative to pipe replacement!
- In fact, pipe lining IS pipe replacement
- The new lining that is installed inside the old pipe is as strong as new pipe
- Has a 50-year warranty
- Only reduces the internal diameter by 5%
- Only takes 3 hours to install
Let’s not forget, since pipe lining requires no excavation, it is cleaner, less invasive and much faster than repiping the old-fashioned way.
Which Pipes Can Be ReLined?
Pipelining, also known as Cured-In-Place Pipe (CIPP) is used for clay pipe replacement, cast iron pipe repair, HVAC pipe repair, storm drain replacement, golf-course overflow drainage pipes, drinking water lines, and sewer pipelining of sanitary sewer pipe.
Does The Whole Pipe Have To Be Lined?
No, especially for clay pipes, only the cracked pipe or root intrusion area is relined. This “sectional repair” is also called a “point repair” and costs a fraction of what relining the whole pipe would cost.
But usually cast iron pipes in residential dwellings and apartments are all of the same age and have experienced the same corrosive environmental conditions, so when one portion of the sewage pipe starts leaking of backing up, usually the rest of the cast iron pipe has to be lined too.
What Type Of Warranty Comes With The Pipe Lining?
Sewer pipe lining comes with a 50-year materials and labor warranty.

Do you use an epoxy spray-on system or is it a physical new pipe that you install inside my old pipe?
One common way to line pipes is to spray a thin layer of food-grade epoxy inside the pipe, like the inside of a can of food. This is called “Epoxy Pipe Lining” and it offers no new physical pipe and so the strength is remarkably less than a pipe liner. Epoxy pipe lining is commonly used in drinking water pipes but is not recommended for pipes that bear any physical load. The slightest ground settlement for example will crack the epoxy and the pressurized water will leak out. However in fire-suppression hydrant water supply pipes or water mains thicker layers up to 4mm are applied in which case the epoxy pipe lining does add structural strength enhancement.
How Much Does Pipe Lining Cost?
Trenchless pipe rehabilitation costs much less than a sewer repipe project. Re-lining 4″ cast iron pipe typically runs $125 per ft. outdoors and around $140 per foot under structures like buildings.

Highlighted Case Study for 2010: Repeated Sewage Backups On Playground
We were called out to a condominium complex that has been experiencing repeated sewage drain line blockages. But the matter has become more urgent, as various unsanitary products are backing up and then bubbling up into family’s gardens where their small children play!
We video inspected their 8″ main sewer pipe line under the road that receives all the waste from the adjacent condos, and it clearly showed that the clay pipe had cracked and pipe joints had opened up, allowing roots to grow into the broken pipe. Those roots were creating the backups reaching all the way into the first floor bathrooms, and when the upstairs second floor toilets were being flushed, the lower floor toilets and sinks would flood. Homeowners are waking up in the morning to find their bathrooms literally swimming in feces.
Plumbers had been out many times to clear out the roots and obstructions, but the pipe perforations simply allowed the roots to grow back later. After charging customers repeatedly for this service, the plumbing companies ultimately recommended the traditional pipe replacement which is very expensive, messy and time consuming.
To replace 350′ of the problematic pipe the old-fashioned way meant that they would first have to apply for a permit which could take days or weeks. Then all the various utilities companies such as city water departments, cable companies and power companies would have to locate and identify where their assets are buries underground so that the excavation hoe does not break them. During construction all the water supply would have to be shut off to the entire neighborhood for weeks, not to mention the damage to people’s yards and landscaping. Also, part of the pipe passes under a road, so traffic would have to be redirected for a period of time. To make matters even worse, the water table was really high, which meant ground water control would have to be applied along the 350’ stretch of excavation.
The plumbing companies estimated the trenching and replacement of pipe would take around 3-5 WEEKS to do and would cost around $60,000 – $75,000.
We repaired the four problematic pipe sections in 1 day for $22,000 using what are called “point” or “sectional” pipe lining.
Sectional pipe lining only re-lines the portion of pipe that is defective, which is ideal for clay pipes which are much more durable than cast iron or Orangeburg pipes. It is estimated that 95% of all clay pipe is in good condition, leaving only 5% that requires lining. What’s more, the pipe lining technology that we used had a “flow through” pipe which allowed for continuous flow inside the pipe during the repair, so that no-one was inconvenienced in the condominium complex.
Also, since sectional lining is generally considered to be a pipe “repair” not “replacement”, no permitting was required and the work could start immediately.
Pipe relining has been used widely in California where broken sewer pipes are common. Some properties like factories and restaurants simply cannot afford the business losses associated with the downtime of replacing the pipes.
Highlighted Case Study for 2009: Residential Home Pipe lining
We received a frantic call from a residential customer. The customer informed us that their sewer line under their house was backed up. We sent out our pipe lining technicians to perform a video inspection. The pipe lining tech performed a full sewer line pipe inspection using CCTV video inspection. The pipe was severely damaged and multiple cracks were seen as well as severe corrosion and joint leaks. The pipelining technician recommended trench less pipelining to reduce downtime and to avoid having to destroy the landscaping and wooden floors inside the house. Our mobile pipelining team was dispatched onsite and a trenchless job was performed without any problems. We performed a full inspection and it was determined that our installation / re-lining was successful. The property manager was ecstatic that we didn’t have to tear up the ground and the job site was left clean without a mess or any property damage from digging. We aim for a clean work site that looks like we were never there and we take the time needed to get it right the first time. Our pipe lining techs are all certified and they are constantly being educated on new techniques.

Since Perma-Liner™ pipe restoration can be installed quickly and quietly beneath houses, apartment buildings, driveways, sidewalks, landscaping, railways, tunnels, shopping centers, malls, military bases and inside ships, there is usually no need to install a plumbing bypass to handle the regular flow.
Even though the diameter of the resulting pipe is slightly reduced, flow actually improves because the smooth PVC lining has a lower coefficient of friction than concrete or clay.
This technology can rehabilitate a 2″-10″ pipe of any kind, and has stood the test of time. It
- Renews pipe life to a minimum of 50 years as per ASTM 1216 third party testing
- Is IAPMO approved and NSF-Sewer Standard 14 Certified
- The Perma-Lateral™ Lining System / Cured-In-Place Pipe (CIPP) is the only system and materials to be approved for lining pipelines in the City of Los Angeles and New York City. The approval has been granted by the Department of Building and Safety per strict Los Angeles Plumbing Code (LAPC) requirements and 3rd party testing. Perma-Lateral™ Lining Materials meet their strict non-stretch liner requirements. Only Perma-Liner™ provides patent non-stretch lining materials. The Perma-Lateral™ liner allows the installer to invert the liner through the existing building sewer pipeline to the city main sewer connection without stretching into the city sewer main. Normal felt liners without the patent scrim can stretch into the city sewer main and cause blockages that require emergency digging and/or robotic cutting devices.
“After performing a sewer pipe video examination, the plumber quoted $50,000 to replace our sewer plumbing in the walls and in our antique marble floors. We would have had to stay in a hotel for 3-4 weeks! Instead we re-lined the pipe from the roof, through the walls and under the floor for only $10,000 in 1 day.” (Graham Thomas, Clearwater, FL)
