Pipe Relining vs Pipe Replacement

Direct answer

Pipe relining avoids major excavation where the existing pipe can still act as a host pipe; replacement is used when the pipe is too collapsed, misaligned or inaccessible for lining.

HydroTrace technical notes

This topic is normally assessed with site conditions, access limitations, pipe material, pipe diameter, CCTV findings and the risk of excavation. HydroTrace uses inspection data to decide whether relining, cleaning, patch repair, replacement or further investigation is the correct remedy.

When this matters

• Commercial buildings with drainage failures under floors.
• Body corporate and estate infrastructure where excavation is disruptive.
• Industrial and mining facilities where downtime is expensive.
• Municipal and stormwater networks with access constraints.
