Concrete cracks are a natural part of the lifecycle of any structure. Repairing these cracks can greatly extend the life of the concrete and minimize safety concerns.

All cracked areas should be investigated. Dormant cracks should be repaired using flexible repair materials that allow for future movements. Active cracks require flexible epoxy or moisture-tolerant epoxies. For professional assistance, you can call Concrete Repair Morgantown WV.

The first step in any concrete repair is understanding what caused the problem. Without this knowledge, it is impossible to design a repair that will work. Once this information is obtained, a thorough preparation process can begin. This includes cleaning the area to be repaired and removing any unsound concrete, contamination, or corrosion products. This can be done using a variety of methods, including nondestructive evaluation techniques. These methods include radar, infrared thermography, and impact echo. These will not damage the concrete but can reveal a lot of information about what is going on beneath the surface.

The preparation stage also involves proper mixing of the concrete repair materials. Concrete mix manufacturers have developed a wide range of prebagged repair products to help contractors make better decisions about which material will work best for a given situation. Many of these repair materials now contain fibers, polymers, and other additives to help the concrete resist cracking, improve strength and durability, and reduce the tendency to shrink.

Another aspect of a good repair is properly dampening the concrete prior to applying the material. This will help the mortar stick to the existing concrete and prevent it from flaking off. It will also allow the repair to set up faster.

When repairing cracks in concrete, it is important to use a concrete repair product that is flexible and can expand and contract with the existing concrete during curing. Most concrete repair products are now formulated with polymers, which can increase their tensile strength and durability. These polymers can also reduce the likelihood of a crack reoccurring in the future.

For large cracks, masonry repair mortar is often used. This is a Portland cement and aggregate mixture with a polymer added to help it adhere to the concrete and resist a crack. For small cracks, a simple epoxy resin or latex product can be applied to the surface and forced into the crack with a putty knife or mason’s trowel. It is then smoothed and leveled with the surrounding concrete.

When repairing spalled concrete, certified shoring must be in place. This can be done using various techniques, but usually includes saw-cutting the repair boundaries and breaking up any loose or unsound concrete. The shoring system should be checked periodically during the repair to ensure it is still adequate.


Concrete patching is a popular method for repairing concrete and making it look good. It isn’t a long-term solution, however, and eventually cracks will appear again. For this reason, it is best to reach out to a professional for concrete repair services to avoid further damage.

Before a concrete patch is applied, it is important to understand the causes of the damage in order to make an intelligent decision on how to fix it. There are a few different concrete patch products on the market that are designed for specific chores, and it is best to choose the one that fits your situation.

First, the surface of the concrete must be cleaned to ensure that the bond is strong with the surrounding concrete. This can be done with a power washer or by hand if the area is small. Then, a concrete patching product should be selected and mixed according to the manufacturer’s instructions. It is important to mix properly to avoid any shrinkage or debonding issues.

In addition, the weather must be appropriate for completing a concrete repair. Concrete works best when it is moist, so a prolonged dry period can cause problems. The hot sun and wind can also take the water out of concrete too quickly, making a patch job less effective.

After the patching compound has been applied, it is important to allow time for it to cure properly. Depending on the climate, this can be anywhere from a few hours to a few weeks. It is also important to remember that the patching compound needs to be properly anchored to the existing concrete. For this, reinforcing steel is usually used.

Some people also like to use textured patching material. This helps to create a more natural appearance and can help hide cracks that are too small for a concrete patch to cover. This type of texture can be added by raking the surface of the patching compound or using a wire brush. It is also possible to add color to a concrete patch with special additives. This can be a fun way to customize your concrete repair and make it look unique.


Concrete crack repair can be a daunting project, especially considering that over 50% of repairs fail within two years. The process of repairing concrete cracks requires careful evaluation, proper preparation, and the use of a method specifically designed to address the problem. This will ensure that your repairs are successful and durable.

Before beginning the concrete repair process, it’s important to understand what caused the cracking to begin with. This will help determine the best method to fix the problem and prevent it from recurring. Cracks in concrete are caused by a variety of factors. Some of these include physical impacts, surface scaling, and weather exposure. When a crack occurs, water and other materials can seep into the concrete and cause damage to the steel reinforcement that holds the concrete together. This can lead to corrosion, which in turn causes the concrete to break down.

Once the root cause of the cracking has been determined, the next step is to choose a repair material. There are many different concrete repair products on the market, each with their own set of characteristics. For example, some have very low shrinkage rates, while others have high compressive strength and abrasion resistance. It is also important to consider what type of structural load the concrete will be exposed to and how quickly it needs to achieve full strength.

The best way to determine which product is right for your specific project is to consult the manufacturer’s instructions. They should provide you with a list of recommended conditions for mixing and pouring the concrete. It’s also a good idea to test the cracking behavior of the repair material with your own samples before applying it to your structure.

As the concrete crack repair is taking place, you’ll want to take the time to feather the new concrete mix into the surrounding dry concrete. This is the stage where you get to channel your inner artist, so don’t be afraid to get creative! This process is not only aesthetically pleasing, but it can also be beneficial for the longevity of your concrete.


Concrete cracks are an unavoidable fact of life, but there are some things you can do to prevent and repair them. A proper preparation of the surface, a good patching job, and the use of a concrete sealant that is suited for your needs are the keys to successful concrete repair.

The first step is to figure out what caused the damage in the first place and then do the necessary preparation by removing loose material, contamination, and dirt to get down to a clean, sound concrete surface. It is important to do this correctly so that the repair will last.

Dormant cracks can be sealed with epoxy resin or polyurethane sealants, which are flexible and will accommodate future movement in the cracks. This is a suitable solution where the movement is considered normal, such as with vibration from traffic or temperature changes, and does not pose a structural risk.

If a crack has water leaking through it, it is best to treat that specific area rather than the entire concrete slab. This can be done with a reactive polyurethane resin that chases the water into tight micro-cracks and pores, sealing the leak and creating a strong bond to wet concrete. This is a quick, simple, and permanent repair for wet or leaking cracks.

If a crack is active and causing structural damage, it may be necessary to replace some or all of the concrete with an appropriate concrete replacement product. This may be a structural repair that is best left to a professional. If the crack is causing only cosmetic problems, it can be repaired by a method called “crack stitching.” This does not close the fissures but stops the movement and may prevent further damage.
