Auger Pressure Grouted (APG) piles are constructed by advancing a hollow-stem continuous flight auger into the ground and pumping grout through the hollow shaft of the auger, producing shafts of grout in the soil. They are a specific system within the industry-termed Auger Cast-in-Place pile (ACIP pile) family (also referred to as Auger Cast Piles or Augercast Piles).
APG piles have been installed to depths of up to about 200 feet. Diameters vary from 12 to 24 inches in 2-inch increments and 30 to 48 inches in 6-inch increments. Berkel installs APG piles in a variety of geologies across the country. Our APG piles have been load tested to over 2000 tons and have been used to support compressive loads of up to 1000 tons.
