What Causes Concrete Problems
There are numerous reasons that concrete can begin to break down or become uneven. Understanding what is causing your concrete to display problems is the first step to finding out how to correct the issue. A lot of concrete problems we see are due to the soil beneath the slabs. When dirt is poorly compacted, overly dry, or too saturated, it shifts and settles beneath the concrete. Once this becomes drastic enough, the slabs will shift and settle with the soil, cracking and becoming uneven.
The top of your concrete is also prone to damage from weather elements. Especially during extreme freeze-thaw cycles, trapped moisture in the porous concrete will expand as it freezes. As a result, untreated concrete surfaces will pit and flake. Chipping and flaking also happen during the winter months when sand and salt are used to keep ice at bay.
