Why Concrete Rises

What causes concrete to sink?

Soil shrinkage and compaction



Soil shrinkage, compaction and settling all have an impact on sinking concrete. If the soil below the slab isn’t compact, the concrete can easily begin to sink as the soil beneath it solidifies and hardens. If the soil is too wet or too dry, this can also cause concrete to sink.
