Sinking Foundations

Raise & Stabilize Your Foundation

Raise and stabilize your foundation. Sinking Foundations occur over time and can cause serious structural problems. A1 Concrete Leveling offers the QuadPower™ Piering System which provides four times the surface area at the base of each pier, producing a load bearing capacity that is superior to competitive methods. Our component parts are manufactured using heavy gauge structural steel, and our QuadPower™ system has been engineered and tested to provide a cost effective and permanent solution in more varied soils and more challenging conditions than any competitive system.

The foundation is excavated, and mechanical lifting brackets are permanently installed onto the foundation. QuadPower piers are
driven below the unstable soil into stable strata. The structure is then hydraulically lifted to a point of optimal practical recovery, and the piers are permanently locked in at the restored position.
The shaft of the pier is filled with cement, and concrete grout is injected into
the void created beneath the foundation to evenly distribute load and provide additional strength.

  • Patented quad-power piering system
  • Patented pumping system provides stable equalized load
  • Engineer approved
  • Transferable Life-of-Structure Warranty
