Why is My New Concrete Driveway Cracking?

Posted on: July 23, 2022

Are you concerned about your new concrete driveway cracking? If so, it’s time to take action! There are several reasons your driveway may be experiencing cracking, including overloading, overcuring, and expansion. Knowing the causes of these problems can help you select the most effective repair method. Read on to learn more! Here are some of the most common reasons why your new driveway is cracking:

Expansion

If you’ve recently poured a new concrete driveway, you might be wondering why it’s beginning to crack. The first two pictures don’t show any cracks. You may be concerned that a deeper crack is developing, but don’t be. In fact, these cracks may just be a sign of shrinkage and aren’t indicative of a larger issue. Cracks may also appear shortly after the concrete has been poured. If not repaired, water can seep into the cracks and expand, making them wider. To prevent this problem, you can seal the cracks with a polymer concrete crack sealant, such as the one offered by Quikrete.

Besides cracks in the surface, concrete can also crack due to other reasons. Excess water in the mix, rapid-drying concrete, or improperly placed joints can cause the surface to crack. In some cases, you may be able to diagnose the cracks yourself, or you can hire a professional to inspect the cracks. There are several possible causes for cracks in concrete, but you should avoid any that can cause serious problems.

Settlement

If you have just installed a concrete driveway, you might be wondering: why is my new concrete driveway cracked? If the cracks are wide, jagged, or irregular, they could be indicative of bigger problems. This may include improper installation or sub-grade issues. However, cracks that are small and irregular aren’t necessarily defective. They just need to be monitored for worsening. Here are some things to look for.

The cracks that appear at the edges are usually a result of concrete shrinking after it is poured. These cracks don’t indicate a larger problem, and are likely caused by heavy vehicles. If the cracks are smaller, you can easily repair them by applying Quikrete Quick-Setting Cement mixed with Acrylic Fortifier. After applying the two products, clean the edge. If the cracks are larger, you can use Quikrete Polymer Modified Structural Repair to repair the entire corner.

Overloading

There are several reasons why you may have noticed cracking in your new concrete driveway. First of all, you should determine the type of crack. There are two types of cracks: structural and overloading. Overloading cracks form when too much pressure is placed on the concrete. This can happen after a rainstorm. Structural cracks are usually found in concrete walls and can be quite damaging.

Another major cause of cracks in new concrete driveways is a lack of joint control. If the slab is not set properly, it may crack due to ground settling. This can happen when the soil underneath the concrete is soft or has been improperly compacted. If you can’t avoid a problem like cracking, consider chip sealing the gravel driveway. If you cannot do it yourself, consider hiring a professional to inspect your driveway.

Overcuring

When you first install your new concrete driveway, it is natural to have some cracks. Some of these cracks will be minor and disappear quickly, but serious cracks may require drilling into the existing slab and tie into the new pour with rebar. Caulk is not a recommended method to fix a larger crack. Cracks can also be caused by tree roots growing under the driveway. Removing these roots can be expensive and may damage the tree.

Generally, large slabs of concrete are made with joints every eight to ten feet. These joints are designed to limit slab movement and shrinkage cracks. Cracks will be hidden within these joints. It is important to follow the instructions of your concrete installers to prevent cracks. Otherwise, cracking will occur. If you notice cracks on your concrete driveway, it’s a good idea to have it repaired immediately.
