Cracked foundation walls are a common problem that can cause homeowners a lot of worry. While some cracks may be minor and cosmetic, others can be a sign of a serious underlying problem. It's important to be able to identify the different types of cracks and understand their causes in order to determine the best course of action.

Causes of Cracked Foundation Walls

There are many different things that can cause cracks in foundation walls, including:

• Soil movement: This is the most common cause of foundation cracks. Soil can move due to changes in moisture content, temperature, or pressure. When soil moves, it can put stress on the foundation, causing it to crack.

• Poor drainage: If water is not properly drained away from your home, it can saturate the soil around your foundation. This can lead to soil movement and foundation cracks.

• Plumbing leaks: Leaks in your plumbing system can also saturate the soil around your foundation and cause cracks.

• Expansive soil: Some types of soil, such as clay soil, expand and contract with changes in moisture content. This can put stress on the foundation and cause cracks.

• Foundation settlement: As a foundation ages, it can settle unevenly. This can cause cracks to form in the walls.

• Construction defects: In some cases, foundation cracks may be caused by defects in the original construction of the home.

Types of Cracked Foundation Walls

There are two main types of cracked foundation walls:

• Vertical cracks: These cracks run up and down the wall. They are usually caused by soil movement or foundation settlement.

• Horizontal cracks: These cracks run across the wall. They are usually caused by expansive soil or water pressure.

Concerns About Cracked Foundation Walls

Cracked foundation walls can be a serious concern because they can allow water to enter your home. This can lead to a number of problems, including:

• Mold growth: Mold can grow in damp environments, and cracked foundation walls can provide the perfect breeding ground for mold.

• Water damage: Water can damage your home's finishes, furnishings, and belongings.

• Structural problems: In severe cases, cracked foundation walls can lead to structural problems with your home.

Solutions for Cracked Foundation Walls

The best way to repair cracked foundation walls is to consult with a professional foundation repair contractor. They will be able to assess the damage and recommend the best course of action. Some common repair methods include:

• Slabjacking: This method involves injecting concrete slurry beneath the foundation to lift it and level it out.

• Piering: This method involves installing 12" solid concrete piers beneath the foundation to support it.

• Crack injection: This method involves injecting epoxy or polyurethane into the cracks to seal them up.

Preventing Cracked Foundation Walls

There are a number of things you can do to prevent cracked foundation walls, including:

• Maintaining proper drainage: Make sure that water is properly drained away from your home by installing gutters and downspouts and grading your yard away from the foundation.

• Watering your lawn: Watering your lawn regularly can help to keep the soil around your foundation moist, which can help to prevent it from cracking.

• Planting trees away from your home: Trees can absorb water from the soil around your foundation, which can lead to cracks. Plant trees at least 10 feet away from your home.

• Checking your foundation regularly: Inspect your foundation regularly for cracks and other signs of damage. If you see any cracks, contact a professional foundation repair contractor immediately.
