As we are all aware, concrete is not a ductile material and it does not bend or stretch without breaking. However, it does expand and shrink with temperature changes, resulting in the cracks you are now seeing at home.
• Home foundation has settled
One possible reason for settling is if a massive tree is removed from the spot near the concrete slab, the unseen roots or buried roots will eventually decompose. When an unsupported concrete slab is placed atop a poorly compressed trench, the void created by settling can cause a crack across it.
• There was a lot of water in the concrete
Cracking resulting from adding excess water in the concrete mixture is called plastic shrinkage cracks.
• The concrete slab dried out too rapidly.
Rapid drying of the slab is another factor that causes the development of cracks on a concrete garage floor. This happens on a concrete slab when the topmost section loses water too quickly.
• Overpressure of the concrete slab.
Another reason why garage concrete floors crack is placing too much weight atop the slap. Even though concrete is a very strong material, just like any building material, it has a load capacity limit. Cracks of this nature occur because the flexural strength of the concrete slab is less than the compressive strength, making the slab twist to its breaking point.
