Photo Album: Underpinning to Repair Foundation Settlement in Gilbert, AZ 1.2022

The owners of this 1996 single family home in Gilbert, AZ reached out to Arizona foundation Solution after noticing several cracks begin to appear throughout the home.   A Level B Foundation Investigation reflected that the home could be experiencing foundation settlement at the western, southern and eastern portions of the home as shown by the damage (aka Signs of Stress) and lower readings on the Topographical 2D Map.      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 it’s Highest Practical Maximum. The piles should be spaced approximately six to 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 western, southern and eastern portions of the home. Arizona Foundation Solutions is an expert on foundation repair cracks all over the valley, especially down in Gilbert, AZ.
