Downpipe Relining Guide

Direct answer

Downpipe relining can rehabilitate vertical drainage stacks and rainwater pipes in buildings where wall chasing or demolition is undesirable.

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.
