How Do You Install Resin Impregnated Pipe Liners into the Existing Pipe?

Plumbing repairs have grown leaps and bounds ever since trenchless technology was introduced. The no-dig CIPP process, or Cured in Place Pipe is now used to rehabilitate storm drains, sanitary sewers and pressure pipelines for gas, process and water effluents.

The CIPP liner results in a “pipe within a pipe” with absolutely little to no disruption in your daily life. The resin impregnated felt tube is simply inserted into any existing manhole, with service connections being remotely reinstated once the process is complete. Suffice to say, trenchless technology is the future, offering a viable, effective solution when for leaky pipes and pressure pipes that have built up significant deposits. But how is this done?

How It Works

The liners used in the CIPP technology is made of a tube-like layer of fiberglass felt or non-woven polyester coated with a polyurethan exterior. The felt tube can hold the special epoxy resin and add a considerable amount of strength once the liner is installed in place.

Catalyzed thermosetting resin is calculated, mixed and impregnated via the wet-out process. When this is completed, the liner is fitted to the installation site and positioned just inside the problem pipe. After that, the liner gets into the existing pipe using smaller trenches or existing points via the inversion method, which utilizes an inversion drum or a water tower with air pressure.

Air pressure or a water column inflates the liner and makes it press against the walls inside the host pipe. While under pressure, the liner is then cured using the most apt methods- using steam or heated water to activate the thermosetting properties. As the liner is inflated, the heat makes the resin harden. After the curing process is completed, the liner is allowed to cool in order to prevent shrinking.

Technicians do a final inspection to make sure that the CIPP is a success and that the problem is solved.

Pipe Liners as “Cure” All

Cured in Place Pipe is an excellent solution to almost all plumbing issues you’ll experience. The liner holds fast to the problem pipe, forming a good seal at the joints. Tree root infiltration will no longer be a problem as CIPP is basically a long piece of pipe that can extend from one manhole to the other. Better still, single liners eliminate any potential infiltration and inflow problems.

CIPP can easily bridge offset gaps and joints if there are any missing pipe sections. The flexibility of the liner makes it the go-to choice for repairing sewer lines that have bends. The liner itself doesn’t rely on the integrity of the existing pipe structure. The diameter of the new pipe is minimally reduced, but you gain considerable benefits such as a noticeable increase of flow within the liner surface material. CIPP can rehabilitate your pipes and make them work for another 50 years or so.

Trenchless Pipe Repairs utilizes only the best trenchless technology in both CIPP and robotics to provide customers top-notch plumbing services. The commitment to deliver quick service is matched only by the company’s dedication for delivering the best solution.
