RESISTIVE PIERS
Avalon installs Resistive Piers as another means of underpinning and raising sunken foundations. Steel shafts are hydraulically driven into the ground until the foundation begins to rise.

During installation, each pier is made to do the work of at least two, thereby achieving a factor of safety. All piers are then pressed down upon to lift the structure back to level.
After the installation of multiple 42-inch segments, Avalon goes beyond the industry standard by placing both rebar and concrete inside the hollow piers.
Resistive piers are available in one foot sections to allow underpinning directly under the foundation with a small jack, as shown in this photo. The pier has been installed to the engineer’s PSI specification. The stand has been put in place and tightened to transfer the load, ready for concrete.
