Why Is My New Concrete Cracking?
There is nothing like smooth and flawlessly poured concrete. So, it is understandable when you start to see new concrete cracking, more so if you have just paid out for a new driveway, garage floor, concrete slab, or walkway. Typically, you don’t have to worry about having to perform concrete crack repair if you start to see fine lines, spiderweb lines, or shattered glass lines, on your concrete surface. Here is why you have cracks in your new concrete and what you should do about it.
Why New Concrete Cracks
Concrete cracks are generally due to normal shrinkage that happens when concrete starts to dry and harden. As concrete dries, the water slowly starts to evaporate from the mixture, and the size of the slab shrinks. The loss of material will create stress cracks in the concrete. Cracks form when these exceed the strength of the concrete.
Are Cracks in a New Concrete Slab Normal?
Yes, cracks in concrete are normal, and they happen when concrete hardens and cures. Concrete can also crack when it starts to experience extremely cold or hot temperatures. Some cracks are inevitable due to the structure. So if you have questions about your new concrete, speak to your contractor.
Plastic Shrinkage” From Water Loss
Before concrete dries, it is often referred to as “plastic,” which is a temperamental stage. Hairline and shrinkage cracks happen due to rapid moisture loss, also called “plastic shrinkage,” before it cures.
Too Much Water Added to the Mix
Plastic shrinkage can happen for any number of reasons, however, excess water in the concrete mix is often a major factor. Adding more water will make the concrete easier to work with. However, once that water has dried, it can result in cracking.
