Concrete Repair: 5 Steps To Fixing Cracks In Concrete

Concrete is a popular building material for good reason – it’s strong, durable, and can be used in a variety of applications. However, concrete is not immune to damage, and over time it can develop cracks. If left untreated, these cracks can lead to further damage and even structural problems. But don’t worry – concrete repair is a relatively easy process, and with the right tools and techniques, you can have your concrete looking good as new in no time.

What Causes Concrete to Crack?

Concrete cracks because of a variety of reasons, but the most common cause is water damage. When water gets into the concrete, it can cause expansion and contraction. This can cause small cracks to form, which can eventually grow into larger ones. Other causes of concrete cracking include poor installation methods, environmental factors (like cold weather), and even weight fluctuations.

How to Repair Small Cracks in Concrete

If you notice small cracks in your concrete, there are some steps you can take to repair them. The first step is to determine the cause of the crack. If it is due to water damage, you will need to repair the concrete using a water repellent sealant. If it is due to freeze damage, you will need to repair the concrete using a thawing agent. If it is due to a structural issue, you will need to have the concrete replaced.

Get a Concrete Repair Company to Fix Your Concrete

If you are noticing cracks in your concrete, it is important to get a concrete repair company to fix the issue. There are a few steps you can take to help ensure the repair goes smoothly:

1. Check for any signs of water damage. If there is water damage, the concrete may not be able to hold up under the stress of a repair.

2. Make sure the repair company has the proper tools and equipment to do the job. Many times, a repair will require a specialized tool or technique that the average contractor may not have.

3. Confirm that the repair company is licensed and insured. A licensed and insured contractor will have both insurance coverage and experience in repairing concrete.

How to Repair Large Cracks in Concrete

If you notice large cracks in your concrete, it’s important to take action before they become bigger. There are several methods you can use to repair large cracks in concrete, depending on the severity.

If the crack is less than 1 inch wide, you can patch it with a mixture of mortar and concrete. For larger cracks, you’ll need to use a more specialized material, such as fiberglass or epoxy. Before you start the repair, make sure to clean the area so that dirt and debris don’t get into the crack and cause it to expand.

Once the crack is repaired, you’ll need to seal it with a coating or sealant. This will help prevent water from seeping into the crack and causing

How to Repair Cracks in Structural Concrete

There are a few different ways to repair cracks in concrete. Depending on the severity of the crack, one or more of the following methods may be necessary:

1. Repair with a sealant

If the crack is small and does not extend beyond the surface of the concrete, a sealant can be applied to the crack and left to dry. Once the sealant has dried, the crack can be filled with a concrete patch.

2. Repair with a grout

If the crack is larger or extends beyond the surface of the concrete, a grout must be used to fill in the gap and then sealed with a cementitious material.

3. Repair with epoxy: 

If the crack is too large or too deep to fix with sealant or grout, epoxy may be necessary. Epoxy is a very strong material and should only be used in cases where the concrete is severely damaged.

4. Repair with fiberglass

In some cases, fiberglass may be the only option for repairing cracks in concrete. Fiberglass is a relatively new material that is still being developed, so it may not be available in all areas.


Concrete is a remarkably tough material, but it’s not immune to damage. If you notice a crack in your concrete, it’s important to determine the cause of the crack and then decide the best way to repair it.
