Initial Problem

Approximately 15m of 100mm Earthenware sewer drain was continually blocking beneath the building due to extensive tree root intrusion. Excavation and replacement of the drain was not possible due to the drain running directly beneath the main offices and the Automatic Teller Machine.

SA Pipe Relining was chosen by the general site builder to investigate an alternative method of drain repair.

Work Performed

Using high pressure water (hydrojet equipment) all tree root intrusion and other obstructions in the drain were removed and the internal bore of the drain was descaled in preparation for relining.

CCTV equipment identified the length of the liner required and the positioning.

The drain was then relined (approximately 15m) and restored to its proper condition, eliminating the need for any excavation works.


The entire project required no excavation and no disruption to general business operations.

SA Pipe Relining worked to a strict 24 hour deadline ensuring all service and full drain rehabilitation was successfully completed and signed off, meeting all project timeline requirements.
