Before getting started with the repair, it is essential to understand the function of foundation walls. Here is a brief overview:

What Is A Foundation Wall?

Foundation walls are load-bearing structures that support the weight of the house above them. They are typically made of concrete, brick, or stone and are reinforced with steel rebar to help prevent cracking. However, over time, foundation walls can settle or shift, which can cause them to crack or bow. If left unrepaired, these problems can lead to serious structural damage.


Signs Of A Damaged Foundation Wall

There are tell-tale signs that your foundation wall may require repair. These include:

  • Cracks in the foundation walls, both horizontal and vertical
  • Doors or windows that stick or will not open or close properly
  • Bowing or bulging of the foundation wall

Any of these signs indicate that the structural integrity of your foundation wall has been compromised and needs to be repaired as soon as possible.

How To Repair A Foundation Wall

There are different ways to repair a foundation wall, depending on the extent of the damage. Let’s check out some of the most common methods.

Assess The Damage

The first step is to assess the damage to your foundation wall. You can start by visually inspecting the wall for cracks, gaps, and bulges. The extent of the damage will determine the best repair method. If the damage is too extensive, it may be prudent to engage a professional contractor.

A professional may go a step further and dig a hole next to the foundation to check for any damage that may not be visible from the outside. They will also check for the stability of the soil around the foundation.

Once you have a good understanding of the damage, you can start to plan your repair.

Foundation Cracks

Foundation wall cracks can range from hairline cracks to cracks several inches wide. The best way to repair cracks will depend on their width.

Cracks less than â…› inch – The best way to repair these cracks is by using polyurethane or epoxy resin. These materials can be injected into the crack with a caulking gun. Once they are in the crack, they will expand and fill the void. This will effectively seal the crack and prevent further damage.

Cracks wider than â…› inch – For cracks that are wider than â…› inch, you will need to use a concrete crack filler. These come in ready-made mortar mixes that you can apply the same way as polyurethane or epoxy resin. Once the filler is in the crack, it will need to be smoothed out with a putty knife.

Cracks wider than ¼ inch -Cracks that are wider than ¼ inch may indicate structural damage and require a more extensive repair. Engaging a pro at this point is recommended.

Here are additional measures that you can take to repair cracks:

Foundation Pier Systems

You may install foundation piers where you attribute the cracks to unstable soils. A foundation pier is a steel pier driven deep into the ground to reach stable soils. The pier is then attached to the foundation with brackets, and the weight of the house is transferred from the unstable soils to the piers. This effectively stabilizes the foundation and prevents further damage.

Foundation Wall Anchors

Another way to stabilize a foundation wall is by installing foundation wall anchors. Wall anchors are steel plate systems that tug the foundation wall back into place while simultaneously stabilizing it. You can use wall anchors to repair cracks and stabilize bowing foundation walls.

If you notice signs of damage like cracks to your home’s foundation wall, it is essential to take action to repair them as soon as possible. If left unrepaired, these damages can compromise the structural integrity of your home. There are several ways of repairing foundation wall damage, depending on the extent of the damage. You can use polyurethane or epoxy resin to fill the void for small cracks. However, for cracks wider than ¼ inch or for any damage that appears to be structural, it is best to engage the services of a professional contractor.
