Foundation Crack Repair in St. Louis, Missouri: Common Services You May Need

Maintaining the strength of your home’s foundation in St. Louis, Missouri, is crucial. Not only does a solid foundation keep the structure sound, but it also ensures your family’s safety and secures your assets. Unfortunately, Missouri’s shifting soil, severe weather patterns, and the aging of your home can weaken this foundation, causing cracks to appear. These small cracks might be early warnings of bigger problems needing quick action. Here is everything you need to know about St. Louis foundation crack repair and finding the right service for your home’s needs. 

Foundational Knowledge of Foundation Cracks in St. Louis 

Foundation issues often stem from a mix of neglect, natural settlement, environmental factors unique to St. Louis County. For homeowners, general maintenance of gutters, downspouts and other areas of potential seepage are crucial.  Additionally, as houses age, it’s natural for their foundations to settle into the earth. However, this process can be exacerbated by the local soil composition and weather patterns. 

St. Louis experiences a range of environmental stresses. From heavy rainfall to drought conditions, these variances in weather patterns can significantly impact the soil’s volume and stability. This constant fluctuation puts uneven pressure on foundations, leading to cracks. 

Additionally, the freeze-thaw cycle common in Missouri winters can cause the ground to expand and contract. These elemental factors further stress foundation materials. Understanding these underlying causes is crucial for St. Louis residents seeking to maintain their homes’ integrity and value.

Types of Foundation Cracks to Look Out For

The appearance of foundation cracks can vary. Each type signals a different level of concern for homeowners. 

Hairline cracks are often seen in new homes. This tends to happen as the concrete settles and cures. The appearance of hairline cracks usually doesn’t indicate serious structural issues. However, we recommend keeping an eye on them.

Vertical cracks run straight up and down or at a slight angle. These types of cracks in the foundation are typically caused by settlement or shrinking. Thankfully, vertical cracks are often easily repaired so long as they are not wider than ¼” and don’t grow wider over time.

Horizontal cracks and diagonal cracks on the other hand, are more alarming. Their presence suggests external pressure from soil or water is compromising the foundation wall’s ability to support the house. 

Lastly, stair-step cracks, which follow the mortar lines between blocks or bricks, can indicate differential settling across different parts of the foundation. This could potentially be a serious issue that may require more extensive intervention.


For homeowners, recognizing the signs of foundation distress early and understanding what these signs mean can save time and money by protecting their homes from long-term damage. 

Proactive measures, like monitoring for new or expanding cracks and consulting with foundation repair experts in St. Louis, can help address minor issues before they escalate. By staying informed about the types of foundation cracks and their implications, homeowners can ensure their homes remain safe, stable, and secure for years to come.

St. Louis Foundation Crack Repair Services

Foundation crack repair maintenance is essential for maintaining the structural integrity and value of your home. Cracks in your foundation can be more than just an eyesore. They can signify deeper structural issues that, if left unaddressed, could lead to significant damage. Fortunately, there are a variety of effective methods to repair these cracks, ranging from simple injections to more comprehensive structural repairs. Let’s explore some of the most effective ways to address foundation cracks, ensuring your home remains safe and sound.

Epoxy Injections

For minor cracks that haven’t compromised the overall stability of the foundation, epoxy injections are a reliable solution. This method involves injecting a high-strength epoxy resin into the crack, which then hardens to seal the crack completely. 

The advantages of using epoxy include its strong bond. Injecting epoxy into the cracks restores the structural integrity of the concrete, as well as its longevity. This is a durable option for crack repair.

Polyurethane Foam Injections

When waterproofing and flexibility are priorities, polyurethane foam injections offer an excellent alternative to epoxy. This method doesn’t just seal the crack. 

Polyurethane foam also expands upon injection, filling any voids and preventing water infiltration. Compared to epoxy, polyurethane offers greater flexibility, making it better suited for cracks that are subject to movement or expansion.

Structural Repairs

In cases where foundation cracks indicate more severe damage, such as settlement or shifting, structural repairs may be necessary. Techniques like underpinning or piering involve reinforcing or stabilizing the foundation to address the underlying issues. 

These options are considered when the type and extent of the damage go beyond superficial cracks. They require a more robust solution to ensure the home’s safety.

Waterproofing Solutions

Preventing future cracks often starts with effective waterproofing. By keeping water away from the foundation by ensuring gutters are free of debris and extending downspouts away from the house, you can significantly reduce the risk of cracks and other related issues. 

Both interior and exterior waterproofing methods can be employed. These options include drainage systems with sump pumps, sealants, and membranes, each designed to protect your foundation from moisture intrusion.

Soil Stabilization

Lastly, soil stabilization plays a crucial role in preventing foundation movement, which is one of the primary causes of cracks. Techniques like water jetting during the prolonged hot summer months may statistically help the soil around the house

These methods help reduce the likelihood of foundation settling. By addressing the issue from the ground up, soil stabilization offers a proactive approach to foundation crack prevention.
