15 Feb How To Fix A Foundation Crack: Expert Guide from AquaGuard

Foundation cracks can cause concerns for homeowners, as they may indicate underlying issues that could compromise the structural integrity of a house. Understanding the cracks and their causes is crucial in determining the appropriate action. Moreover, assessing the severity of the crack and knowing when to ask for a professional’s help are vital steps in ensuring your home’s long-term stability.

In this expert guide from AquaGuard, we will delve into the essentials of how to fix a foundation crack. 

Understand Foundation Cracks 

Understanding the different types of foundation cracks is vital for homeowners as it helps distinguish between minor issues and those that might indicate more severe structural problems.

• Tiny Cracks (Hairline): These are the most common and usually show up a few days or weeks after a new foundation is built. They happen because the concrete or mortar is drying out. However, it is not something to worry about.
• Up-and-Down Cracks (Vertical): Typically resulting from shifts in groundwater pressure due to soil contracting and expanding. Unless water seeps in, the crack is getting wider, or many cracks are accompanied by wall bending, it is usually not a cause for concern.
• Side-to-Side Cracks (Horizontal): These types of foundation cracks indicate that there may be big issues within the structure caused by significant groundwater and soil pressure. It is important to get a professional to check it out right away.
• Stairs-like Cracks (Stair-step): If the cracks resemble a set of stairs, they are usually not a big deal. But if they show up with other problems, such as parts of the house not being level, it might mean there’s a more serious issue.

Moving on to common causes of foundation cracks. Soil movement can exert pressure on the foundation, whether due to expansion, contraction, or shifting. Water damage from leaks, poor drainage, or excessive moisture can weaken the foundation over time, contributing to crack development. Poorly executed construction practices, such as inadequate reinforcement or substandard materials, may also form foundation cracks.

Assess the Severity of the Crack 

Before understanding how to fix a foundation crack, a homeowner should assess the characteristics that differentiate structural from cosmetic cracks. These characteristics include type, size, location, and progression. Hairline cracks may not be alarming, but branching out irregular patterns or locations near corners may indicate more significant issues. Also, assess whether the crack grows over time, as this could signal an ongoing problem.

Suppose a crack is accompanied by other signs like doors and windows sticking or uneven floors. In that case, it might indicate a more severe structural problem. Pay attention to any changes in the appearance of the crack or the surrounding areas, as these could provide valuable insights into the underlying issue.

Certain warning signs should prompt immediate professional evaluation. These include cracks wider than ¼ inch doors or windows that no longer close properly or noticeable shifts in the foundation. If you observe these signs, seeking expert advice is crucial to prevent further damage.

• Masonry Patching Compound: Essential for cosmetic repairs, ensuring a smooth finish and restoring the appearance of the foundation after the crack is filled.
