Are constructed by rotating a continuous-flight, hollow-stem auger into the ground to the specified bearing depth, or until the refusal criteria are reached. Fluid grout is then pumped, under pressure, through the hollow stem and out of a port on the bit, as the auger is withdrawn in such a way to exert a positive grout pressure on the soil surrounding the hole. Piles are commonly reinforced to resist different loads.
A concrete pile, either reinforced or prestressed, which is manufactured in a construction yard or at the site, and, having been properly cured, are installed using vibratory equipment or hammers to penetrate ground.
Are dimensionally square steel beams that are driven or drilled and grouted in the ground to support structural loads. Although designed for some skin friction, a H pile is most effective transferring the load from the top to the tip. Commonly used in areas with denser soil types.
A helical anchor/pile is an extendable deep foundation system with helical bearing plates welded to a central steel shaft. Load is transferred from the shaft to the soil through the plates.
