Centralizers For centering a single bar in a piling, drilled shaft, or caisson. Currently available in two sizes. 11" and 15".
Reinforcement is placed into fluid grout/concrete immediately after an auger is removed. Contractors often install a single, full-length bar into the center of the pile, & a cage of partial-length bars around the perimeter of the pile. The full length bar provides continuity, & acts as a guide for the cage. The full-length bar is also used for tension resistance. In this case, the Centralizer is installed on the end of the bar to anchor the bar in the grout.
