Cleaning and CCTV Investigation of Culverts

Before Queensland Rail could refurbish 24 culverts, they needed to understand the condition they were in. The Aaro experts were able to clean, investigate and report back to Queensland Rail, using machinery and equipment on hand.

Aaro was engaged by Queensland Rail to clean and provide CCTV investigation reports on 24 culverts along the North Coast Line, near Townsville, Queensland. 

Aaro cleaned the culverts using a high-pressure jetting truck and then removed the excess material by way of mini-digger and a tipper truck.

The investigation was to determine the suitability for the rehabilitation using a resin pre-impregnated Cured-In-Place Pipe (CIPP) liner, such as the iMPREG Liner from Germany.

The culverts ranged in diameter from 350mm to 1350mm, with a total length of approximately 450m which required cleaning.
