If you have concrete around your house, whether it is on the sidewalk or wall, you are going to be all too familiar with cracking. Concrete cracks are pretty much unavoidable, especially when laid on top of soil. Even a thick slab of concrete is no match for shifting soil. Soil shifting is the main cause of concrete cracks.

Why Cracks Need to Be Repaired

Most cracking is minor and it is not going to really have an effect on the structural strength of your concrete, besides the fact that it is going to be visible and unsightly. In reality, most concrete crack repair is purely cosmetic. But, it is still smart to repair small cracks if they are large enough to be patched. If you leave a crack not patched, there is a good chance that it will get bigger. This is particularly true with cracks on sidewalks. If you are constantly walking on the surface, you can wear that down the edges of the crack and make them more pronounced. So, it is always a good idea to fill your concrete cracks as soon as you notice them.

Of course, some cracks are going to be too small to be filled. That is, they are so narrow that it wood be impossible to add any crack filler into them. But, once a crack is over about 1/8" wide, you should consider patching it.

Applying Concrete Patch

Concrete patch is super easy to work with and inexpensive. You can use premixed patch that comes in squeezable, resealable tubes. This means that you can squeeze it right into the cracked area. Then, you just use a plastic putty knife with a flexible blade to scrape the top and flatten the patch. You want to try and keep the patch off of the top of the concrete surface.

The patch is probably not going to match perfectly with the existing concrete because of natural fading and staining. You can usually fix this by using concrete stain or glaze. However, you will have to do this to your entire slab of concrete come so it is a lot more work to consider. Your best bet is to just leave the patch as it is, and let the colors fade and blend together naturally over time.

Patching concrete is an easy DIY project, and you should not put it aside or wait to make the repairs. To learn more, visit a website like
