Your home’s foundation is one of the most critical structural elements, ensuring the stability and safety of the entire building. Over time, foundation cracks can appear due to various factors, and if left untreated, they can lead to significant structural damage, water seepage, and costly repairs. Addressing foundation cracks promptly is essential for the long-term integrity of your home. In this blog, we’ll explore the causes of foundation cracks, effective repair solutions, and why Lakhwa Chemical Services is a trusted name in foundation crack repair.
Common Causes of Foundation Cracks
Understanding the cause of foundation cracks is the first step in addressing them. There are several factors that can contribute to the development of cracks in the foundation:
- Soil Movement and Settlement
Soil movement, such as shifting, settling, or expansive soil (which swells when wet and contracts when dry), is a common cause of foundation cracks. As the soil under the foundation shifts, it puts pressure on the foundation walls and leads to cracks. - Water Damage
Excess water from rainfall, snowmelt, or plumbing leaks can soften the soil beneath the foundation, causing it to shift and weaken. This can result in cracks in both concrete and brick foundations. Hydrostatic pressure, when water accumulates around the foundation, can also force water into existing cracks. - Poor Construction Practices
Foundations that are not built to code or use substandard materials can develop cracks over time. Poor workmanship, improper curing of concrete, or inadequate drainage systems can all contribute to the appearance of foundation cracks. - Age and Wear
As homes age, the foundation may naturally settle or shift. This can result in minor cracks that occur gradually over many years. While these cracks may not be structurally significant at first, they can worsen over time if not addressed. - Thermal Expansion and Contraction
Concrete and other foundation materials expand and contract with temperature fluctuations. This movement can cause the foundation to crack, particularly in areas with significant seasonal temperature changes. - Tree Roots
Large trees planted near a home can cause damage to the foundation. As tree roots grow, they can exert pressure on the foundation, causing cracks or even lifting sections of the foundation.
Types of Foundation Cracks
Not all foundation cracks are created equal, and some may indicate more severe issues than others. There are several types of foundation cracks:
- Vertical Cracks
Vertical cracks are typically caused by the natural settling or shifting of the foundation. They are generally less serious than horizontal cracks but still need to be addressed to prevent water penetration and further damage. - Horizontal Cracks
Horizontal cracks are more concerning as they typically indicate significant structural problems, such as water pressure or expansive soil pushing against the foundation walls. These cracks may compromise the stability of the foundation and require immediate attention. - Diagonal Cracks
Diagonal cracks, often seen near corners or windows, are caused by uneven settling or shifts in the foundation. While they can be caused by minor soil movement, they may also point to deeper foundation issues that require repair. - Stair-Step Cracks
Stair-step cracks occur in brick or block foundations and follow the pattern of mortar joints. These cracks are usually a result of settling or moisture-related issues, such as improper drainage or hydrostatic pressure.
How to Repair Foundation Cracks
Repairing foundation cracks is essential to maintaining the integrity of your home’s foundation and preventing water damage. The method used to repair the cracks depends on the type, size, and severity of the crack, as well as the cause of the damage.
- Epoxy Injection
Epoxy injection is one of the most effective and commonly used methods for repairing cracks in concrete foundations. The process involves injecting an epoxy resin into the crack, which hardens and bonds the cracked surfaces together. This method is ideal for smaller, non-structural cracks. - Polyurethane Foam Injection
Polyurethane foam injection is used for cracks that may allow water seepage into the basement or crawl space. The foam expands upon injection, filling the crack and creating a waterproof barrier. This method is effective for both small and large cracks. - Foundation Piering
For more severe foundation issues caused by soil settlement or shifting, foundation piering may be necessary. This process involves driving steel piers deep into the ground to stabilize and lift the foundation. Piering can be a more invasive and expensive solution, but it’s effective for major foundation problems. - Crack Sealing
For small cracks that don’t penetrate deeply, crack sealing with a flexible sealant may be sufficient. This involves applying a sealant to the surface of the crack to prevent moisture from entering and causing further damage. - Wall Bracing and Reinforcement
If foundation walls are bowing or showing signs of significant movement, wall bracing or reinforcement may be necessary. This can involve installing steel braces or carbon fiber straps to stabilize the walls and prevent further shifting. - Drainage Solutions
If poor drainage is the cause of foundation cracks, addressing the drainage issues is essential. Installing French drains, improving grading, and ensuring proper gutter systems can help prevent water from accumulating around the foundation.
When to Call a Professional for Foundation Crack Repair
While some minor cracks can be repaired as a DIY project, foundation crack repair often requires professional expertise, especially for larger or more serious issues. Here are some signs that it’s time to call in a professional:
- Visible Structural Damage: If you notice significant cracks in load-bearing walls, bowing foundation walls, or doors and windows that no longer close properly, it’s crucial to call a professional.
- Water Seepage: If water is entering through the cracks, it’s important to address the issue immediately to prevent further damage to the foundation and the basement or crawl space.
- Worsening Cracks: If the cracks are widening or growing in size over time, this may indicate a deeper structural issue that needs to be addressed by a foundation repair specialist.

Q. How big of a foundation crack is serious?
A. Cracks wider than 1/4 inch or those that are expanding, cause water seepage, or occur in load-bearing walls should be treated seriously and evaluated by a professional.
Q. What to seal foundation cracks with?
A. Small cracks can be sealed with epoxy or polyurethane sealants. Larger cracks may require more advanced methods, like foam injection or structural repair, depending on the severity.
Q. Can foundation cracks be repaired?
A. Yes, most foundation cracks can be repaired using various methods like crack sealing, epoxy injection, or foundation stabilization techniques, depending on the crack’s size and cause.
Q. How to fill cracks in concrete?
