JSI has developed unique equipment for the installation of Auger Cast Piles. These are pilings constructed by rotating a hollow stem auger into the ground to a predetermined depth and then pumping a high strength grout mix into the shaft while the drill is withdrawn. Reinforcing steel is then placed to design specifications and elevations are checked of both steel and grout.All of our equipment utilizes a fixed drilling mast in lieu of a crane with hanging drill leads. Our mast design is able to be leveled in 360 degrees allowing for greater control of the auger and straighter piles.

In addition to this, the auger may be placed with great accuracy on the survey pin location due to the fine placement controls the machines are equipped with. The auger is withdrawn using a powerful hydraulic cylinder rather than a cable hoisting method. This provides a smooth continuous lifting motion unobtainable with and crane and thus decreasing the chances of soil intrusion into the newly casted pile. This reduces “redrills” and excess grout left on the job site. Another Advantage our machines offer is faster set-up times and lower mobilization expenses. Typically we can be ready to drill with 1 hour of site arrival. This is especially important on smaller jobs and projects that may require multiple mobilizations.
