The apartments were built on piles however, the slab-on-grade was not. The first floor SOG starting settling drastically due to the FILL layers below. In some instances,the differential settlement was 8 inches or more. To make the situation worse, the original contractors poured another slab on top of the SOG to try and solve the issue. Unfortunately, this made the slab settle more due to the addition weight. Helical piles were the premier choice to be used to help support and end the settling.
