Common Reasons Concrete Settles and Sinks in South Florida
Concrete is heavy! When the soils underneath a concrete slab are unable to support its weight, the slab will sink.
If part of the concrete slab is supported by soils and other sections are not, the unsupported pieces may crack away from the other section and result in unlevel concrete.

Primary Causes of Sinking Outdoor Concrete:
1: Soil Shrinkage, Compaction & Settling
Different types of soil have different load-bearing capacities. When a soil's load-bearing capacity is exceeded, the soil will compact and settle.
Changes in the amount of moisture in the soil can affect the soil underneath your concrete slab. When the soil gets wet, it holds water and expands in size. When the soil becomes dry, it begins to shrink, creating voids (or empty space) under the slab, resulting in uneven, cracked concrete.
2: Soil Washout
The soil that is underneath your driveway, patio or concrete steps may not necessarily remain there to provide adequate support for the concrete element. Water from heavy rains and plumbing leaks can find its way underneath your concrete slab and wash away the soil that's supporting the concrete.
As water moves underneath your concrete slabs, it can wash away the soil that's supporting the weight of the concrete. As this happens, it creates a void, or empty space, underneath. Over time, with nothing to support it, your concrete slab can begin to sink or cave in.
3: Poorly Compacted Fill Soil
During installation of a concrete driveway, patio, sidewalk or foundation, if the new concrete is poured on top of loosely compacted soil, the slab is more likely to settle.
As the fill soil underneath the concrete slab compresses and settles, this creates voids under the slab. With nothing supporting the slab, the concrete cracks and sinks.
