Have you noticed that the concrete foundation of your home is uneven? Over time, shifting ground can cause settling around the edges or other areas of your foundation, leading to shifting and sinking in those spots. This can create an unsightly look for a home, as well as weakening its structural integrity.
To restore the exterior appearance and protect your property from further damage, you need to know how to fix an uneven concrete foundation. In this blog post, we will go over what causes foundations to settle and crack in some places versus others and provide a step-by-step guide on how to fix uneven concrete foundation.
If you believe your concrete foundation is uneven, there are many do-it-yourself techniques that can help bring it back to its ideal form. Uneven foundations occur due to shifting soil, aging structures, and other environmental conditions that cause the ground below a concrete foundation to give way or experience an unequal distribution of weight.
In this blog post, we’ll discuss some of the best practices for fixing an uneven concrete foundation without having to call in expensive professional help.
What Causes Uneven Concrete Foundation?
There are many reasons why concrete foundations can become uneven over time. Some of the most common causes include:
1. Poor Soil Compaction
One of the most common causes of uneven foundation is poor soil compaction. This is especially true for newly poured concrete, as the soil beneath it may not have been properly compacted before the slab was put in place. If this issue is not addressed quickly, the concrete will start to settle and become uneven.
2. Hydrostatic Pressure
Hydrostatic pressure is the force of water pressing against a structure. It can cause concrete foundations to settle, resulting in unevenness. This is particularly common during heavy rain or flooding periods when water builds up around the foundation and exerts additional force on it.
3. Poor Construction
In some cases, uneven concrete foundations may be caused by poor construction. This can include issues such as improper curing, inadequate drainage, or incorrect mixing of the concrete. All of these factors can lead to an uneven foundation and should be addressed immediately.
10 Ways About How to Fix Uneven Concrete Foundation
Once you have identified the cause of your uneven concrete foundation, you can then begin to address it properly. How you choose to fix the issue will depend on the cause, but some common solutions include:
1. Use a Concrete Grinder to Flatten the Surface
This is one of the most popular methods as it can be done quickly, with minimal mess and disruption. However, you’ll need to rent or purchase a concrete grinder and know how to use it before attempting this method. Also, this method is most suitable for small areas as it takes time to grind larger surfaces.
2. Pouring a Layer of Self-Leveling Concrete
This is a great option for foundations that have minor unevenness and only require the slightest touch-up. The self-leveling concrete will seek out the lowest points on your foundation and fill them in. Make sure you follow the instructions carefully as you mix and pour.
3. Lifting the Foundation With Hydraulic Jacks
If the issue is caused by an underlying issue, such as a settling foundation, then hydraulic jacks can be used to lift it back into place. This is an effective method, but it will require the expertise of a professional contractor. Be careful not to try this yourself, as it can be dangerous.
4. Use Polyurethane Foam to Fill the Space
This is an effective method for small areas and only requires a few simple steps. The foam expands and hardens beneath the surface, providing support and preventing further settling or cracking in the area. Also, the foam is easy to use and clean up.
5. Applying a Concrete Resurfacer
This involves applying a special compound that bonds with the existing concrete, providing a smooth and even finish. This method can be used indoors and outdoors and fix minor issues such as cracks or shallow holes.
6. Applying a Slab Jack
This method involves lifting the foundation by injecting foam into the space beneath it. This method can be used for both interior and exterior applications, but it requires the help of a professional contractor.
7. Installing Piers or Posts to Stabilize The Foundation
If a settling foundation causes your unevenness, then installing piers or posts can help provide additional support. Make sure you work with a professional contractor to avoid any mistakes.
8. Installing Concrete Pads
Concrete pads are great for providing additional stability and preventing further settling problems. This is an effective method, but it may require the help of a professional to install it properly. But you have to make sure that it is done correctly to avoid further damage.
9. Raising the Foundation With a Mud Jack
This method involves using hydraulic pressure and an inflatable rubber bladder to restore the foundation. This process takes time and requires the help of a professional contractor, so make sure you hire someone experienced in this type of work.
10. Replacing the Foundation
In some cases, replacing the entire foundation may be more cost-effective. This major project requires a lot of time and money, so make sure you weigh your options carefully before making this decision. It may also require the help of a professional contractor as well.
Frequently Asked Questions
How Many Levels of Uneven Concrete Foundation Can Be Fixed?
This depends on the extent of the damage. If the levels are minimal, fixing one or two areas of uneven concrete may be possible. However, if there is extensive damage, more than two areas may need to be addressed. In this case, a professional should be consulted in order to determine the best course of action.
What Are Some Causes for Uneven Concrete Foundation?
The most common causes for uneven concrete foundations are soil erosion, water runoff, and inadequate subgrade preparation prior to foundation installation. Other factors, such as seismic activity or tree roots, can also cause damage to a foundation.
Also, settling can occur over time if the ground was not properly compacted after foundation installation.
What Are Some Solutions for Uneven Concrete Foundation?
The solutions for uneven concrete foundations vary depending on the severity of the damage. In some cases, soil may need to be removed from underneath the foundation and replaced with a new base layer. In other cases, the entire foundation may need to be replaced.
If the damage is minimal, it is sometimes possible to use a leveling compound or concrete patching material to even out the surface. It is important to note that all of these solutions should only be undertaken by experienced professionals to ensure they are completed correctly and safely.
What Are the Benefits of Fixing an Uneven Concrete Foundation?
Fixing an uneven concrete foundation is important in order to prevent further damage. This can include cracking, shifting, and heaving, eventually leading to structural instability. Fixes also provide a smoother surface for walking or working on top of the foundation, reducing tripping hazards.
Finally, fixing an uneven concrete foundation can increase the value of a property as it will be in better condition and more aesthetically pleasing.
Are There Any Risks Involved with Fixing Uneven Concrete Foundation?
Yes, there are risks involved with any kind of structural repair. Improperly completed repairs can lead to further damage and even structural collapse. It is only important to use experienced professionals to ensure that the repairs are completed correctly and safely.
Additionally, it is important to be aware of any safety hazards that may come up during the repair process, such as working with heavy materials or using hazardous tools.
Fixing an uneven concrete foundation is a big undertaking that experienced professionals should only do. It is important to understand the causes, solutions, and risks involved to ensure the job is completed safely and correctly. Doing so can help ensure that your home or business stays structurally sound for years to come.
Conclusion
If your home has an uneven concrete foundation, don’t despair. There are a number of ways to fix the problem. Often, the least expensive and most effective solution is adding support piers or jacks under the sagging beams. In some cases, replacing part of the foundation may be necessary.
Whatever course of action you take, it’s important to get professional help to repair your foundation properly.
