Dual concrete drifts for an underground coal mine. In their own words on the day: this is not work for everyone. It is work for us.
A drift is the sloping tunnel that carries people and machines from the surface into a mine. Lining two of them meant moving concrete 1,550 metres from the pump, day after day, at 120 cubic metres a day. For scale, that line is fifteen football fields laid end to end, and the concrete arrives at the far end still workable and still to spec.
Distance like that is a pressure problem, a mix problem and a logistics problem at once. The Putzmeister BSF 2110 Moli and the 2109 trailer pump shared the push, the mix was designed for pumpability over the full run, and the surface crew kept agitators cycling so the line never sat still. A parked line at that length is a lost line.
Mine sites also run the tightest inductions and supervision in the industry. We grew up in the Hunter's mining economy, so those regimes are home ground for our crews rather than an obstacle.
Both drifts were delivered in April 2026. Big distances, big volumes, no excuses.
We grew through the Hunter Valley's mining boom in the 1980s, and long line, high pressure work has been part of the fleet ever since. The same capability carried the 650 metre push at Sydney Metro Pyrmont East and shows up any time a pour sits a long way from where a truck can stand.
Volume, date, and what the access looks like. We will come back with the right unit for the job, and if the site is tricky we will look at it first.
