Aaro and their Indigenous Partner, Yurra completed emergency works for Rio Tinto to sleeve a collapsed corrugated steel culvert with a new steel pipe.
Aaro was required to push the steel sleeve through the existing culvert from the short side of the collapsed area. Excess material was excavated, and high pressure jetted through the culvert. Once the steel pipe was in place, each end of the culvert was capped and grouted by hand, with the void then being grout filled by use of a pump. Aaro then poured an in-situ headwall for the culvert.
Aaro was also required to complete additional earthworks on the access track and two rail crossings.
