INSTALLATION OF FOUR (4) PUSH PIERS. THESE PIERS WILL BE INSTALLED ALONG THE NORTH AND WEST WALLS. THIS WILL BE ACCOMPLISHED BY EXPOSING THE FOOTING OF THE FOUNDATION FROM THE INSIDE AND INSTALLING LOW-PROFILE BRACKETS. ONCE THE BRACKETS ARE INSTALLED, PUSH PIERS WILL BE HYDRAULICALLY PRESSED INTO THE GROUND THROUGH THESE BRACKETS TO A MINIMUM PRESSURE OF 3,750 PSI. ONCE EACH INDIVIDUAL PIER HAS REACHED PRESSURE, WE WILL TRANSFER THE WEIGHT OF THE FOUNDATION ONTO THE PIERS, STABILIZING AGAINST FURTHER MOVEMENT.
