How does a CIPP rehabilitation work?

CIPP rehabilitation is an advanced repair solution with several advantages over conventional methods. Here’s a step-by-step guide of this minimally invasive procedure:

  1. Evaluation: The first step in CIPP liner installation involves a detailed assessment of the pipe using specialized cameras. This helps determine the damage and strategize the rehabilitation procedure.
  2. Clearance: The existing pipe is thoroughly cleared of debris and obstructions using high-pressure water, facilitating a firm bond of the new liner.
  3. Preparing the liner: A flexible liner, doused in epoxy resin, is custom-configured to match the specifications of the pipe requiring repair.
  4. Insertion: The resin-infused liner is inserted into the compromised pipe using an inversion technique, or sometimes pulled into place. The choice of method depends on the pipe’s specific conditions and requirements.
  5. Inflation: After positioning, the liner is expanded using an air or water bladder, pressing the resin-coated liner against the interior walls of the existing pipe.
  6. Curing: Following inflation, the liner is given time to cure. In this phase, the resin hardens, forming a solid, durable, and uniform pipe within the existing pipe.
  7. Final inspection: Upon full curing of the liner, a conclusive inspection is performed using specialized cameras. This verifies the successful execution of the CIPP rehabilitation and confirms the new pipe is ready for use.

Depending on the use, CIPP pipe lining can last up to 50-60 years or more if well maintained.

A cured-in-place pipe can be relined more than once if needed. However, the chances of needing to are slim due to long-lasting effects that prevent failures.

Cured-In-Place Pipe lining is typically made of a flexible tube or fabric material impregnated with a thermosetting resin, such as epoxy or polyester, which hardens and cures to create a durable lining within the existing pipe.

CIPP lining is installed by inserting a resin-impregnated flexible liner into the existing pipe, curing it to create a new, seamless lining adhering to the interior of the original pipe.

The cost of CIPP liner installation varies depending on factors such as the extent of damage, size of the pipe system, and location.

CIPP rehabilitation can be applied to a variety of existing pipes, such as clay, concrete, cast iron, PVC, and more, making it a versatile trenchless pipe rehabilitation method.

The cost of pipe coating varies depending on factors such as the extent of damage, size of the pipe system, and location.

CIPP lining generally lasts for 50 years or more, with durability influenced by installation quality, original pipe condition, and maintenance practices.
