The installation of pipes using auger boring is a tried and proven technology that has been used for over 50 years.
The principal of the company, Jim Perry has had 40 years experience in the auger boring industry. During this time as a contractor he has completed hundreds of bores ranging from 200mm to 1500mm in diameter. These bores have varied from soft flowing formations up to 200Mpa rock.
Historically, auger boring was used for the installation of underground infrastructure that did not require high accuracy grades usually produced using laser guided micro-tunnellers. This is no longer the case with the advent of hydrostatic levels and sophisticated walkover electronic tracking systems and pilot hole systems to monitor line and grade.
The auger boring machine has the capabilities to install steel or concrete pipe in soft formation, as the cutting head progresses. These pipes can be used as the product pipe, or as an encasing pipe, with the product pipe installed inside the encasing pipe on completion of the bore.
In rock the bores can be completed with the installation of a pilot hole followed by a larger diameter cutter. An encasing pipe is not always installed as the bore progresses but the product pipe is installed in an open hole on the completion of the bore. Alternatively, an encasing pipe can be installed during the drilling process as per soft formation drilling, if required.
