How To Patch Concrete Cracks

Posted on

If you have a concrete driveway or foundation, you have to expect that the surface is going to crack a little bit over time. However, cracks aren't always something that you need to be overly concerned with. Small stress cracks are completely natural and more or less unavoidable. Of course, they can be patched on the top, but it is not always necessary or recommended. This article explains when and how to patch concrete cracks.

Are Your Cracks Big Enough?

It is important to realize that not all cracks are going to big enough to be filled. That is, many stress cracks are so narrow that there isn't room for the liquid crack filler to go into them. Usually, it isn't even worth filling a crack that is less than 1/8" wide. But, once a crack starts to become wider, you should consider filling it. Patching a crack can ultimately protect and prevent it from growing wider. That is, once a crack is filled, the edges will be covered and they will be less likely to chip away or rub down.

If your concrete is cracking due to soil shifting underneath the slab, crack filler isn't really going to permanently solve the problem. It is no match for the strength of growing tree roots and Mother Nature. But, crack filler can prevent surface damage and ultimately keep your concrete looking nice and clean.

Patching Concrete

The key to taking care of your concrete cracks is to always keep an eye on them and fill them as quickly as possible. The work is easy to do yourself, with just a few basic tool. As long as you have a putty knife, you can fill your cracks just like a pro. One helpful tip is to just spread the crack filler inside the gap only. You don't want to spread it on to the top of the concrete surface where it will just rub and chip away. You can scrape the surface so the edges blend in and there are no ridges. If the texture does not match, you can sand down the crack after it dries. This will help it blend in and it could knock down any ridges that are creating a trip hazard on your concrete.

As you can see, it is not difficult to repair cracks, but it could be if you wait too long and let your them become too big. For more information, contact a business such as Mershon Concrete.
