The "no dig" option also known as CIPP

Cured in place pipe (CIPP) drain lining provides a solution to worn and damaged drainage pipes.  The CIPP approach does not involve any digging up of broken pipes to replace them.  Instead a faster and more efficient technique known as 'inversion' is used to mould a new pipe inside the damaged pipe.  The flexible resin mould sets rigid and tight to the old, damaged pipe; there is minimal reduction in pipe diameter.

The advantages being immediate repair and restoration of flows, minimal disruption to traffic, no dig means no site restoration or additional materials required and no need for ancillary traffic management.

The Process

  1. A full and comprehensive CCTV report and inspection is conducted to ascertain faults in the pipe leading to problems such as leaking and root intrusion.
  2. Upon concluding that a new drain lining is required, an above the ground drain lining approach is used to feed a specially formulated resin in a flexible liner through the existing damaged pipe.
  3. Inflating the flexible liner to expand to the old pipe, the curing process then takes place.
  4. On completion the flexible liner is removed leaving a tightly fitted rigid new pipe.
  5. Lateral cuts can then be made.

The pictures surrounding the text in this section shows an illustration of the process from inspection to completion.
