Why are there large cracks in my yard?
Cracks on lawns are caused by a lack of moisture and soil type. In soils with a higher ratio of clay, drought conditions can cause the moisture content within the soil to drop very low. The soil contracts as the moisture is removed. This contraction pulls the soil apart and as it shrinks, causes cracks on the surface.

What causes concrete to crack?
Just like a balloon, heat causes concrete to expand. When concrete expands, it pushes against anything in its way (a brick wall or adjacent slab for example). When neither has the ability to flex, the expanding force can be enough to cause concrete to crack.
What causes cracks in concrete slabs?
Instead, what is more likely to occur is excess overload on the ground below the slab. After a heavy rain or snowmelt when the ground below is soft and wet, excessive weight on the slab can press the concrete down and result in cracks .

There are two common types of cracks brought on by premature drying. Crazing cracks are very fine, surface cracks that resemble spider webs or shattered glass. When the top of a concrete slab loses moisture too quickly, crazing cracks will likely appear. While unsightly, crazing cracks are not a structural concern.
Why does concrete crack when it freezes?
When the ground freezes, it can sometimes lift many inches before thawing and settling back down. This ground movement brought on by the freezing and thawing cycle is a huge factor contributing to concrete cracking. If the slab is not free to move with the ground, the slab will crack.

An excessively wet mix is a contributing factor to shrinkage in concrete. While water is an essential ingredient in every concrete mix, there is such a thing as too much water.
