What causes basement cracks?

Settlement: Cracks in basement walls or basement floors are a common problem that can be caused by a variety of factors, but one of the most common is settlement. As homes settle, the weight of the house shifting down onto the foundation can cause cracks to form. In some cases, these cracks are simply cosmetic and pose no structural threat. However, in other cases, they can allow water to seep into the basement, which can lead to further damage. 

Temperature changes: As anyone who has lived through a cold winter knows, temperature changes can cause all sorts of problems. Pipes can freeze and burst, ice can form on sidewalks and driveways, and cracks can appear in walls and foundations. While most of these problems are an annoyance, foundation cracks can be serious, as they can lead to leaks and even structural damage. Temperature changes are the most common cause of foundation cracks, as the ground freezes and contracts, putting pressure on the foundation. In addition, changes in moisture levels can also cause the ground to expand and contract, putting additional stress on the foundation, foundation walls, and basement floor.

Water: One of the most likely causes of cracks in basement walls and basement floors is water. Water can seep it way into cracks in the foundation and cause them to widen, leading to leaks and flooding. In addition, if there is excessive moisture in the soil around the foundation, it can cause the soil to expand and place pressure on the foundation, causing basement floor cracks. 

Repairing and sealing cracks in basement floor

Now that we know what can cause basement floor cracks, let's talk about sealing your basement floor. Sealing cracks in you basement wall and basement floor is important because it can prevent water from seeping in and causing further damage.

Step 1: Clean the crack

The first step in sealing a basement floor crack is to clean the area around the crack. This will ensure that the concrete sealant adheres properly and prevents dirt and debris from getting trapped in the crack.

Step 2: Repair Damage

If the crack has caused any damage to the surrounding area, it's important to repair this before sealing the crack. This may involve filling in small holes or cracks with a concrete patching compound. Once the compound is in place, use a trowel to smooth it out and make sure it's level with the surrounding surface.

Step 3: Apply sealant

Once the area around the crack is clean, repaired, and dry, it's time to seal the crack itself. There are a variety of sealing products on the market, so it's important to choose one that is specifically designed for concrete crack repair. Apply the repair sealant to the crack, using a putty knife or caulk gun, and make sure to smooth it out so that it's level with the surrounding surface.

Step 4: Allow the sealant to dry

Once the sealant is in place, it's important to allow it to dry completely before walking or driving on it. Depending on the product you use, this can take anywhere from a few hours to a few days.
