If you are not getting all of the items above included with your foundation inspection, then you will likely not have repairs that are designed to remediate the specific issues (soil problems, drainage, weather history, etc.) affecting the performance of your home's foundation.
At Arizona Foundation Solutions, our Forensic Engineered Report (or FER) contains ALL of the 17 items referenced above. We use licensed, professional engineers to interpret the data collected, diagnose the problem, and suggest a repair plan.
The first step is to address the cause of the crack. Once the cause of the concrete crack has been identified and addressed, you can repair the concrete.
For interior & exterior slab cracks, our Crack Stitching method addresses the crack while allowing for some future movement. The end result is a repair that lasts.
