Directional Drilling Australia began as an excavation contractor in 1983 with Backhoes and Polclain rubber tyred Excavators by 1986, Directional Drilling Australia was one of the first companies to specialize in rock excavation, offering the then new technology of excavator mounted rock breakers, the company worked in 2 areas, Demolition and the installation of utilities in the Rock, much of this work was either in the Iron stone rock of the Darling Ranges or coastal sandstones.
Rock saw trencher either wheel of chain type are most cost effective method of excavating long lateral linear meter of rock as it cuts a uniform vertical trench unlike rock barkers which have to brake piece by piece V shaped trench to gain depth therefore excavating larger volumes than required, rock breakers are tedious process that produces boulders and poor quality back-fill unlike the finely ground and consistent powder or crumbed spoil produced by the milling action of the trencher which is an excellent back-fill material.
