Understanding How Pipe Relining Works

Pipe relining, also known as cured-in-place pipe (CIPP) lining, represents a forward leap in infrastructure repair, specifically designed to tackle the challenges of water conservation and system efficiency.

Initial Inspection and Preparation

The process begins with a meticulous inspection of the existing pipes, typically employing closed-circuit television (CCTV) cameras. This step is crucial as it allows technicians to assess the extent of the damage and tailor the relining process accordingly. Following this assessment, the damaged pipes are thoroughly cleaned to remove any obstructions, ensuring a smooth surface for the lining to adhere to.

The Relining Process

After cleaning, the core of the relining takes place. A flexible tube, soaked in a special resin, is introduced into the damaged pipe. This liner is then expanded to fit snugly against the broken pipe itself’s interior walls. Heat or ultraviolet (UV) light is applied to cure the resin, which solidifies the liner, essentially creating a new, robust pipe within the old structure.

Advantages of Pipe Relining

The newly formed pipe is not only leak-proof but also resistant to corrosion, significantly extending the lifespan of leaking pipes in the water system often up to 50 years. Moreover, as this technique is performed beneath the ground, it spares the landscape from the scars of excavation, conserving the environment and the water otherwise needed for traditional repair methods.

Versatility and Efficiency

Pipe relining is distinguished by its adaptability to various pipe sizes and materials, including those used for water, and sewer lines, and gas lines.
