How to Easily Repair Cracks in Your Concrete Foundation

If you’ve noticed cracks in your concrete foundation, don’t panic! While this is a common problem that can indicate structural issues, it’s usually nothing to worry about. Fortunately, there are some simple steps you can take to repair cracks in your concrete foundation and maintain its stability for years to come. From identifying the issue and preparing for repairs all the way through filling large cracks with the best product available – we’ll cover everything you need to know about repairing those pesky problems in no time flat!

Identifying Cracks in Your Concrete Foundation

Cracks in your concrete foundation can be a sign of serious structural damage and should not be ignored. It is important to identify the type of crack, its cause, and any signs of structural damage before attempting to repair it.

Types of Cracks: There are three main types of cracks that can occur in a concrete foundation; vertical, horizontal, and diagonal. Vertical cracks usually run up and down the wall or slab while horizontal cracks tend to run across the surface. Diagonal cracks typically appear at an angle from one corner to another corner on the same side.

types of crack to identify

The most common causes for cracking in a concrete foundation are soil settlement or movement beneath the structure, improper installation techniques used during construction, changes in temperature causing expansion and contraction cycles over time, and excessive weight placed on top of the structure such as heavy vehicles driving over it regularly or large amounts of snowfall accumulation during winter months.

Identifying cracks in your concrete foundation is the first step to repairing any damage. Now that you have identified the type of crack and its cause, it’s time to prepare for the repair process.

Preparing to Repair Your Concrete Foundation

Cleaning the Area: Before you can begin repairing your concrete foundation, it is important to properly clean the area. This includes removing any dirt, debris, and vegetation that may be present. If necessary, use a pressure washer or garden hose to remove stubborn dirt and grime from the surface of the concrete. Once all of the debris has been removed, allow the area to dry completely before proceeding with repairs.

Assessing the Damage: After cleaning up your concrete foundation, it is time to assess any damage that may have occurred over time. Look for cracks in both horizontal and vertical directions as well as signs of structural damage such as crumbling or bulging walls or floors. Take note of any areas that need repair so you can gather supplies accordingly for when you start repairing them later on.

Make sure you have enough material on hand prior to starting repairs so there won’t be any delays due to lack thereof during the project completion stage down the line. This will ensure that you can begin and complete your repair job without any hiccups along the way. Having the right supplies ready beforehand is key for the successful completion of your concrete foundation repair project in a timely manner.

By preparing the area, assessing the damage, and gathering supplies you can ensure that your concrete foundation repairs will be done correctly and efficiently. Now let’s look at how to actually repair those cracks in your concrete foundation.

Repairing Cracks in Your Concrete Foundation

Filling smaller cracks in your concrete foundation is a relatively easy task. You will need to purchase a concrete patching compound from your local hardware store and mix it according to the instructions on the package. Once mixed, you can use a trowel or putty knife to fill in any small cracks that are present. Make sure to smooth out the patching compound so that it blends in with the surrounding area.

Sealing Larger Cracks: Sealing larger cracks requires more effort than filling smaller ones, but it is still an achievable goal for most homeowners. To seal larger cracks, you will need to purchase an epoxy-based crack filler from your local hardware store and apply it according to the instructions on the package. The epoxy should be applied liberally into each crack until they are completely filled and then smoothed over with a trowel or putty knife so that they blend in with their surroundings.

By taking the time to repair any cracks in your concrete foundation, you can ensure that it remains strong and stable for years to come. To maintain its integrity, regular inspections and preventative maintenance are key – let Big Easy Concrete help you keep your concrete foundation in top condition.

Maintaining Your Concrete Foundation

Regular inspections of your concrete foundation are essential to ensure that it remains in good condition. It is important to look for any signs of cracking, shifting, or other damage. If you notice any changes in the structure of your foundation, contact a professional immediately. Additionally, if you live in an area with extreme weather conditions such as high winds or heavy rains, it is important to inspect your foundation more frequently than normal.

Preventative Maintenance Tips: To keep your concrete foundation in top shape and prevent future problems from occurring, there are several maintenance tips that can be followed.

First and foremost, make sure that all water sources around the home are properly diverted away from the foundation walls so they do not become saturated with moisture which can lead to cracks and other issues over time.

Secondly, check for any tree roots growing near the foundation walls as these can cause shifts and instability if left unchecked. Finally, seal any cracks or joints on the exterior of the house regularly to help protect against water seepage into the interior spaces of your home.


Can you fix cracks in the foundation yourself?

No, it is not recommended to try and fix cracks in a foundation yourself. Foundation repair should be left to professionals who have experience and knowledge of proper techniques. Professional contractors will also use specialized tools and materials that are designed for long-term stability and strength when repairing foundations.

Trying to fix cracks in a foundation yourself can lead to further damage or even collapse if done incorrectly. It is best to contact Big Easy Concrete for professional assistance with any foundation repairs you may need.

What do you fill foundation cracks with?

Foundation cracks can be filled with a variety of materials, such as epoxy injections, polyurethane foam injections, or hydraulic cement. Epoxy injection is often used to fill and seal larger cracks in concrete foundations.

Polyurethane foam injection is ideal for filling smaller cracks and sealing them against water infiltration. Hydraulic cement is an excellent choice for filling large voids in concrete foundations that have been caused by erosion or weathering.

All three methods are effective at preventing further damage to the foundation and providing a long-term solution for your home’s structural integrity.

Is it normal to have cracks in the concrete foundations?

Yes, it is normal to have cracks in concrete foundations. Cracks can be caused by a variety of factors including settling, temperature changes, and soil movement. It is important to regularly inspect your foundation for any signs of cracking or other damage.

If you notice any significant cracks or other structural issues with your foundation, contact a professional immediately for an assessment and repair plan. With proper maintenance and regular inspections, most small cracks can be prevented from becoming larger problems down the road.

What is the best product to fill large cracks in concrete?

The best product to fill large cracks in concrete is a polyurethane or epoxy injection. These materials are injected into the crack and then expand as they cure, filling the entire void and creating a strong bond with the existing concrete.

Polyurethane and epoxy injections provide an effective seal that can last for years without needing to be replaced. They also come in various colors so you can match them to your existing concrete color scheme. With proper installation, these products will help prevent further damage from occurring due to water infiltration or freeze/thaw cycles.


It’s important to remember that when it comes to repairing cracks in your concrete foundation, the best way to ensure a successful repair is by taking the time and effort to do it right.
