Plastic shrinkage concrete cracks. When concrete is still in its plastic state (before hardening), it is full of water. When that water eventually leaves the slab, it leaves behind large voids between the solid particles.
Expansion concrete cracks. 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).
Heaving concrete cracks. 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.
Settling concrete cracks. On the other hand, ground settling below a concrete slab can also cause cracking. Settling cracks typically occur in situations where a void is created in the ground below the concrete surface.
Concrete cracks caused by overloading the slab. Although concrete is a very strong building material, it does have its limits. Placing excessive amounts of weight on top of a concrete slab can cause cracking.
Concrete cracks caused by premature drying. 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.
