Use of auger-cast piles has increased dramatically since the late 1970s, when concrete pumping technology enabled piles to be constructed with concrete instead of a sand-cement grout mix. The Starsol rig, introduced into the auger-cast market in the early 1980s, was designed to overcome some of the problems associated with auger-cast piling. The Starsol rig's essential feature is its internal tremie, which constructs a concrete pile shaft of high quality that, in turn, allows for higher concrete working stresses. The Enbesol quality-control system provides real-time pile-construction parameters, enabling rig operators to identify potential problems and rectify them during pile construction. Hard copy print-outs provide clients with a permanent record of a completed pile. Following an independent research project conducted on the load-bearing capacity of the Starsol pile, it was determined the piles could be designed as concrete piles and injected under low pressure.
