Overtime, soils will weaken and shift from moisture, causing the structure on top of them to shift and settle as well. That is exactly what has happened here causing the large crack in this car port's concrete floor.
These piers are designed to transfer the weight of the structure on top to load bearing soil to permanently stabilize the foundation. In most cases, helical piers may also raise a structure back to its original position as well.
After the piers are installed, the holes are refilled and the job site is cleaned up. This car port's foundation is stabilized for decades to come now!
