APGD Pile
Solving An Age Old Problem?
The Auger Pressure Grouted Displacement (APGD) Piling
construction method has helped solve an age old problem that has always
haunted the APG pile: what to do with the augered spoil the continuous
auger conveys out of the ground.
Spoils are minimal 
as the APGD begins its descent. Minimal spoils are especially critical in contaminated soils.

is being injected,
inspectors 
can monitor essential information
about the process outside the cab. The Berkel
patented bit displaces the soil while drilling the pile, and when the
auger is removed there are
minimal spoils

rebar and reinforcing cage are inserted 
.
Today APGD piles can be installed to depths up to 75 feet with design capacities of more than 175 tons. Pile diameters available are 14, 16, and 18 inch diameters. APGD piles can be used in certain soil conditions. To view APGD projects click Project Focus or click Contact Us to request a Berkel & Company Contractors, Inc, DVD.
