Supply and installation of 25m deep earth electrodes for 7 x timber pole aerial earths. The project was carried out for Mackex Services for and on behalf of Sydney Trains.

The project had a tight deadline with works to be completed prior to a 2-day possession weekend. With live overhead conductors imposing height restrictions and a tough cobblestone substrate, Earthing Solutions used a small drill rig employing rotary hammer case drilling techniques using the Robit system to drill to 25m.

Earthing Solutions was the first company in Australia to successfully use the Robit system on such a compact drill.

Challenge: Mastering the new drilling equipment and techniques.

Result: Despite some minor setbacks, the project was completed successfully and prior to deadline.
