Foundation Repair Photo Album: Repairing Foundation Settlement in Prescott, AZ 12.2021
This 2006 Prescott, AZ single-family home was experiencing a foundation settlement issue. We believe that the proper way to permanently stop the perimeter foundation settlement is to underpin the areas that are experiencing movement.
Underpinning is the process of installing deep foundation elements called piles. Piles are engineered foundation supports that are driven down past the unstable soils and are then locked up into load-bearing strata, which can support the loads that are transferred to them. Once the piles have been installed, they can be used to lift the perimeter foundation up to its Highest Practical Maximum. The piles should be spaced approximately eight feet on center and should start and stop near the hinge points of movement (exact spacing to be determined after load-bearing calculations).
In this case, the piles would be located at the east, northeast, and southeastern portions of the home and at the northeast portion of the garage.
Preparing to Underpin
After the pier install area has been excavated, we prepare the Supportworks piers & brackets for installation.
Excavation Complete
The excavation is complete along the side of the Prescott, AZ home.
Preparing to Underpin
Some areas require a hand ding while others (like the one pictured) allow for an excavator to remove the soil.
Excavating Rock
Some areas of Arizona have incredibly rocky soil. In order to remove larger rocks, we must break them up.
