Therefore, if the PSI weight is too excessive for the ground underneath the slab of concrete to carry, it will typically crack. Even though concrete is a very strong material, just like any building material, it has a load capacity limit. This happens on a concrete slab when the topmost section loses water too quickly.Īnother reason why garage concrete floors crack is placing too much weight atop the slap. The former type of crack, crazing, is a fine crack that appears like a shattered glass or spider web. The result is that the top becomes too crusty and so when the stamp is embedded, it quickly pulls the surface apart and causes small cracks at the concrete slab edges. It typically happens on windy or sunny days when the top-most section of the concrete slab dries out faster than the bottom. The latter type occurs during the stamping process of the concrete. There are two types of cracks under this cause: crazing cracks and crusting cracks. Rapid drying of the slab is another factor that causes the development of cracks on a concrete garage floor.

As it shrinks, it drags the granular sub-base creating stress that pulls the concrete apart. As soon as this slab loses the excess moisture, it shrinks.

However, that is far from the truth, and in fact, the prime suspect for cracking in garage floors!Ĭracking resulting from adding excess water in the concrete mixture is called plastic shrinkage cracks. Before the concrete hardens (in a plastic state), it is full of water, which takes up lots of space and increases the size of the concrete slab. While most concrete contractors know that too much water in the concrete mixture does not result in an optimally strong slab for garage floors, many of them still repeat the same mistake! They believe that if excess water is added to the concrete, it makes it easier to install.

Often, the said trenches are not compacted when refilled. Sometimes referred to as subsidence, settling is common over trenches where plumbing pipes and utility lines are buried. The decomposed roots cause a void and cause the foundation to settle a bit and the concrete to develop some cracks. 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. In the first one or two years, a newly constructed home will have its foundation undergo some changes that may make the garage floor settle a bit. Common Causes of Cracks in a Garage with a Concrete Floor 1) Home foundation has settled So, let’s first understand the reasons that the concrete floor in a garage may develop cracks, and thereafter discuss what to do if you have what it takes to repair it. Before you do any repairs on the crack, you need to know what has caused it in the first place. Concrete Contractors see these situations all the time and, in some situations, a homeowner can easily repair the cracks by themselves. Garage floor cracks are common and not necessarily a warning of serious structural issues. While it may indicate foundation problems, that is not always the case. However, it does expand and shrink with temperature changes, resulting in the cracks you are now seeing in a newly built home. As we all know, concrete is not like a ductile material, and so it neither bends nor stretches without breaking. Imagine your shock when you walk out to your car and find a massive crack on the garage floor in the concrete! It has only been a few months since your contractor finished your home and now you must deal with the cracked concrete. You’re all excited that you have finally moved into your brand-new home and gotten everything settled.
