How to Fix a Leaning Foundation Wall

Are you dealing with a leaning basement wall? This can be an alarming experience, the sight of it often raising fears of serious structural damage. But don’t panic. 

How to Fix a Leaning Foundation Wall

There are actually several options available to you when faced with a leaning foundation wall, and many cases can be rectified without major repair – as long as it’s addressed promptly. In this blog post, we’ll discuss why foundations may lean and provide detailed information on how to fix a leaning foundation wall in order to keep your home safe for years to come.

What Causes a Wall to Lean?

Leaning foundation walls can be caused by a variety of issues. Most often, the cause is related to soil conditions that have changed over time or due to problems with the construction of the foundation itself. Poor compaction during construction can result in settling and shifting of soils which can put a strain on a foundation wall causing it to lean. 

Other causes may be water table fluctuations, hydrostatic pressure, or poor design. Regardless of the cause, it is important to identify and address the issue quickly in order to prevent further damage.

The most common signs of a leaning foundation wall are visible cracks along the mortar joints or wall itself, buckling walls, and gaps between interior walls and floors. If you notice any of these signs, it is important to contact a foundation expert as soon as possible.

It is also critical to identify the cause of the learning before attempting to fix it. The repair will depend on the underlying reason, and an experienced professional can help determine which solution is best for your specific situation. 

In some cases, the repairs may involve underpinning the wall with piers, repairing or replacing existing footings, reinforcing cracks or buckles, and water management solutions. In other cases, structural reinforcement of the wall itself may be required.

10 Methods How to Fix a Leaning Foundation Wall

1. Excavate the Soil Around the Foundation

One of the first things you can do to fix a leaning foundation wall is to excavate the soil around the foundation. This will allow you to see how much the foundation has shifted and what caused the shift. 

Make Any Necessary Repairs

It will also allow you to make any necessary repairs to the foundation before refilling the excavation. If you have an area of the foundation wall that is leaning outward, then you will need to dig out around it and remove any loose soil. However, if the foundation wall is leaning inward, then you will need to excavate around this area as well.

2. Remove any Debris from the Area

Once you have excavated the soil around the foundation, you will need to remove any debris that may be present. This includes leaves, twigs, rocks, and anything else that could potentially interfere with the repair process.

Remove as much debris as possible, ensuring that the area remains clean and free from any obstructions. Although it is a good idea to use a shovel, you may also want to consider renting an industrial-grade vacuum in order to get the job done more efficiently.

3. Install Foundation Anchors

If the foundation has shifted due to soil erosion, you may need to install foundation anchors. These are devices that are placed into the ground and attached to the foundation wall in order to provide additional support. The anchors can be made of steel, concrete, or wood.

Depending on the type chosen, they will need to be installed either at a certain depth or at certain intervals along the foundation wall. After installation, you will need to make sure that they are properly secured and tightened.

4. Use a Hydraulic Jack to Lift the Foundation

In some cases, it may be necessary to use a hydraulic jack to lift the foundation back into place. This is typically only done if the foundation has shifted significantly out of place.

To ensure that the job is done safely and effectively, it is recommended that a professional foundation specialist be hired to perform this repair. They will know the exact steps to take and the proper equipment to use in order to restore the foundation wall.

5. Install Helical Piers

Helical piers are devices that are screwed into the ground and used to support a foundation. They can be used in conjunction with a hydraulic jack or on their own if the foundation needs only minor support.

If your foundation wall is only slightly leaning, a professional contractor can install helical piers to provide the necessary support. However, if the leaning is more severe, you may need to use an underpinning system along with helical piers for additional support.

6. Use Steel Braces for Additional Support

If helical piers alone are not enough to support your leaning foundation wall, you may need to use steel braces in addition. These braces can be attached to either side of the wall and provide extra stability. Hiring a professional for this step is important, as installing steel braces requires specialized knowledge and safety precautions.

If done incorrectly, it could lead to further damage. Steel braces can provide additional support and help ensure that the wall remains in its original position, even if there are soil movement or erosion issues.

7. Fill in Any Gaps with Cement Mix

Once you have installed all of the necessary supports, you will need to fill in any gaps with the cement mix. This will help to stabilize the wall further and prevent any future shifting from occurring.

Use a trowel to spread the cement mix evenly across the gaps, then allow it to dry completely before moving on to the next step. After the cement mix has hardened, you can begin to patch any cracks or holes in the wall that may have occurred during installation.

8. Allow the Cement Mix to Cure Fully

After filling in all of the gaps with cement mix, you will need to allow it to cure fully before proceeding with any further repairs. This typically takes 24-48 hours, depending on conditions such as temperature and humidity levels. During this time, be sure to keep the area dry and protected from any possible water damage or other weathering. Once it has cured fully, you will be able to proceed with the steps of repair.

9. Backfill with Soil and Replant if Necessary

Once the cement mix has fully cured, you can begin to backfill the area with soil. If necessary, you may also want to replant any vegetation that was disturbed in the repair process. This will help ensure that everything looks as close to normal as possible after your repairs are complete. 

Be sure to use an appropriate soil mix for the area and take care not to damage any existing plants. However, if the soil is compromised due to drainage issues, you may want to consider using a different soil. This can help improve the overall health of your foundation and any plants that are nearby.

10. Monitor the Foundation Regularly

Once your foundation repair is complete, it’s important to monitor the area regularly for any signs of shifting or settling. If you notice anything out of the ordinary, you may need to repeat the repair process or hire a professional for additional assistance. 

Check the walls for any visible signs of stress, such as hairline cracks or shifts in the mortar. If you see any changes,

Things to Consider When Fixing a Leaning Foundation Wall

1. Identify the Cause:

Before attempting to fix a leaning foundation wall, it is important to identify what caused the problem in the first place. Common causes of leaning walls include soil erosion, poor drainage, excessive moisture, and hydrostatic pressure, and improper backfilling. Knowing the cause can help you determine the best solution for your situation.

2. Consider Your Repair Options:

Once the cause has been determined, it is important to consider the various repair options available. In some cases, simply installing additional structural supports or reinforcing existing structures may be enough to restore stability. In other cases, a more comprehensive approach may be necessary, such as replacing old wall material or even rebuilding part of the foundation wall itself.

3. Hire a Professional:

Fixing a leaning foundation wall is not a job for amateurs or DIY enthusiasts due to its complexity and potential risks. Hiring an experienced professional will ensure the job is done properly and safely, saving you time and money in the long run.

4. Keep Water Away From Your Home:

Proper drainage is essential to preventing a leaning foundation wall problem from occurring again in the future. Make sure that your gutters are clear of debris and redirecting water away from your home, and consider investing in a sump pump or other waterproofing system if necessary. Taking these preventative measures now can help you avoid costly repairs down the line.

Make Sure That Your Gutters Are Clear
