Reduced noise – Auger Cast in Place Grouted Piles are pumped and drilled pile. This eliminates the chances of heavy noise pollution created by hammer impacts when driving piles.
No unpleasant vibrations – The exclusion of working with a pile installation hammer enables the installation of Auger Cast in Place Grouted Piles next to present structures without endangering or weakening existing walls, footings and other structural elements by vibrations.
Auger Cast in Place Grouted Piles can be utilized as an economical and cost effective alternative to other pile types in various situations.
Auger Cast in Place Grouted Piles are completely flexible in length up to the maximum lengths that can be installed with the mobilized pile rig. On projects that have variable lengths, waste of material can be drastically reduced owing to the fact that the placement of material is halted at the drilling grade. The pile contractor does not have to select the accurate length of the pile for each location prior to installation.
The Auger Cast in Place Grouted Pile is also much more flexible in size with dimensions that can be changed quickly by simply changing the guide devices and auger flighting using the same pile rig, allowing freedom of installation of a range of sizes for load testing that can help determine the most competent size or the installation of diverse sizes for various capacities on one project.
An Auger Cast in Place Grouted Pile can have a very irregular shape. This greatly boosts friction capacity of the pile in various soil conditions.
Seeing as an Auger Cast in Place Grouted Pile is cast in place, concerns about shipment like the length of the material or the handling and moving of piles at the jobsite are non-existent.
Casing is not required – In its installation, pile auger is filled with earth that maintains the pile hole’s shape during the drilling phase. The pressures produced by the head of grout in the auger during the grouting phase and withdrawal can exceed the pressures exerted laterally by the soil. While the grout is present in a fluid state, the pressures per foot of depth of the soil are lower than the lateral pressures per foot of depth of the grout.
Installation is possible with restricted headroom condition – Auger sections can be assembled to accommodate the installation of Auger Cast in Place Grouted Piles particularly inside existing buildings that have a clearance limit of 7 feet to 10 feet.
Inspection of soil can be done at each pile hole – Displacement of soil occurs while drilling and pumping grout and is available for testing or inspection.
When faced with different conditions in the soil, before installing a test pile, it is possible to drill probe holes at various locations on the site. This enables the inspecting engineer to successfully and accurately appraise the conditions of the soil and work out the most efficient location for the placement of a test pile. Since no material is wasted the cost is economical compared to other types of probe piles.
