Pipe Lining / Trenchless Pipe Repair / Pipelining / RePipe Without Digging

June 14, 2010 by  
Filed under Back-ups & Pipe Lining

Whether you have roots causing blocked drains, rusted iron pipes, leaking pipes in walls or floors, pipe lining is the modern alternative to pipe replacement. In fact, pipe lining IS pipe replacement, as the new lining that is installed inside the old pipe is as thick and strong as new pipe, has a 50-year warranty, only reduces the internal diameter by 5%, and 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.

Pipelining Is Fast and Clean

In essence, pipe rehabilitation process works like this:

  1. Clean the pipe using high pressure jetting, or in the case of leaking pipes in apartments, using mechanical brushes
  2. Video inspect the pipe to gather distance information
  3. Cut to size the correct length of felt tube liner material that will be impregnated with self-hardening epoxy resin
  4. Saturate the lining material with the resin and install the liner, usually from outside the building or from the rooftop
  5. Inflate the liner to push the resin against the inside pipe wall
  6. Cure for 3 hours
  7. Video inspect the final lined pipe and test all plumbing

Pipe Lining FAQ:

Which Pipes Can Be Lined?

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, and most of all 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?

This type of sewer pipe repair 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.

How Much Does Pipe Lining Cost?

Trenchless pipe rehabilitation costs much less than a sewer repipe project. For actual cost comparisons of residential pipe lining, commercial pipe lining and apartment pipe lining jobs, see our Featured Projects section.

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: Chicago Residential Home Pipe lining

We received a frantic call from a residential customer in Chicago. 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 plumber/pipe lining techs are all certified and they are constantly being educated on new techniques. We take pride in being the best pipelining company in all of Illinois and it shows.

Craftsman Pipe Lining – Underground Pipe Repairs

Craftsman Pipe Lining specializes in trenchless pipe repairs with the Perma-Liner™ inversion process that uses the existing pipe as a host for a new inner pipe. Since no excavation is required it is less expensive and faster than traditional dig-and-replace methods, so municipalities and property owners save millions in construction work and downtime. We can line any 2”-10” pipe whether it is cast iron, clay or Orangeburg without damaging utilities and sprinkler lines, and put back in service the same day. If needed, collapsed sections of pipe are replaced with PVC before the entire length of pipe is relined to ensure total seamlessness.

“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)

Typical Applications

  • Damaged sewer lateral relines with water infiltration or ex-filtration
  • Hurricane-damaged down spouts, cracked vertical internal gutters in high rises
  • Rotted pipes beneath restaurant and factory floors
  • Corroded cast iron or deteriorated clay pipes
  • Cracked pipes and offset joints from settlement or earthquakes
  • Root intrusion & damage
  • Repairing storm water lines
  • Find out more!

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.
