There are many different methods for installing drilled shafts, including: conventional auger drilling, slurry displaced drilled shafts, oscillation and reverse circulation, just to name a few.
The use of drilled foundations is a growing technology nationwide that provides a reliable long lasting solution. More recently, a trend has developed among architects, engineers and owners pushing for larger diameter and longer drilled shafts to be installed.
Kelly Tractor has introduced a redesign of the IMT A125 hydraulic drill rig to the North American market. The rig, built in collaboration with IMT and Caterpillar OEM Solutions Group, is Tier 4 compliant and designed to lay flat for easy transport.
Even the most conscientious and careful drilled shaft installation program can be subject to incidents during construction. Bad weather, unexpected delays in concrete delivery, equipment breakdowns or unanticipated ground conditions can produce imperfections or defects in the completed drilled shaft foundation.
