Upgrade your pipe repair services with Repiper’s step-by-step sewer pipe relining method, tools, and products.

How does it work?

Sewer pipe relining is a revolutionary repair approach that offers numerous benefits over traditional methods. Here’s a simplified step-by-step rundown of how this non-invasive process works:

  1. Inspection: Before the relining process begins, a thorough inspection of the sewer pipe is performed using specialized cameras. This helps to determine the extent of the damage and plan the relining process accordingly.
  2. Cleaning: The existing sewer pipe is then thoroughly cleaned using high-pressure water jets. This step ensures that the new liner will adhere properly.
  3. Preparation of the liner: A flexible liner, saturated with a two-part epoxy resin, is prepared. The liner is custom-made to match the length and diameter of the sewer pipe being repaired.
  4. Insertion: The saturated liner is inserted into the damaged pipe using a technique called inversion, or it may be pulled into place. The method used depends on the pipe’s specific conditions and requirements.
  5. Inflation: Once in place, the liner is inflated using an air or water bladder. This presses the epoxy-soaked liner against the inner walls of the existing sewer pipe.
  6. Curing: After inflation, the liner is left to cure. During this time, the epoxy hardens, forming a robust, resilient, and seamless pipe within the existing pipe.
  7. Final inspection: Once the liner has fully cured, a final inspection is performed using the specialized cameras. This ensures that the sewer pipe relining process has been successful and the new pipe is ready for use.
