Repair

What are the techniques that we use for drainage repair?

All techniques currently in use for drainage repairs are approved by local Water Authorities and the Water Research Centre (WRC).

No-Dig or Trenchless Repairs

This popular drain repair service that we offer is a “no dig” repair. As the name suggests, this repair does not require excavations and instead encompasses various lining techniques. The result is a speedy, reliable fix that won’t dent your pocket.

No-Dig Repair options vary depending on the application, but they all involve inserting a liner into a drain which is impregnated with resin. The liner is moved into position, whether it is local or full length, and then inflated to give a water tight repair by effectively making a thin strong layer inside the existing drain. When the required cure time has elapsed, the means of inflating the repair is removed to restore the full drain function and integrity.

Localised Structural Repairs (LSRs)

  • Patch Liners – This localised repair offers a cost-effective solution to fix individual defects within a drain or sewer.
  • Ambient Cured Lining – Ambient cured lining consists of the full or partial lining of sewers or drains to cover multiple defects.
  • Heat Cured Lining – This is like Ambient cured lining; however, Heat Cured Lining is predominantly used for larger diameter pipes or where an increased resistance to chemical attack is required.
  • Excavation – Excavation is the traditional method of drain repair and replacement and a technique used for new drains, drain replacement, to rectify collapsed drains or to gain access to lining repairs.
