Foundation Crack Repair in St. Louis: A Comprehensive Guide

Have you recently spotted a crack forming along the foundation of your home in St. Louis, and found yourself wondering how much trouble you might be in? Foundation cracks can be more than just an eyesore. They can signify deeper structural issues that may jeopardize the safety and value of your home. Factors such as soil expansion following prolonged St. Louis rain patterns, and even construction techniques can lead to these unsettling fissures. Ignoring foundation cracks could lead to water damage, mold growth, and a decrease in property value. Understanding the common causes behind these cracks and the importance of swift repair is crucial to maintaining your home’s integrity. Here’s everything you need to know about foundation crack repair in St. Louis!

Understanding Foundation Cracks

Maintaining the integrity of your home’s foundation is paramount to ensuring the safety, comfort, and overall value of your property. The foundation acts as the bedrock upon which the rest of your home stands. Therefore, its condition directly impacts the structural integrity of your entire house. 

Recognizing and addressing issues with your foundation early on can prevent minor problems from escalating into major concerns that require costly and extensive repairs. In this spirit, understanding the types of foundation cracks and their implications is a crucial step for any homeowner.

Hairline Cracks

Hairline cracks are among the most common and least alarming types of foundation cracks you might encounter. These small fissures are typically no wider than a credit card. 

They often result from a house’s natural settling and do not usually signify a structural problem. However, it’s wise to monitor them over time to ensure they don’t widen or multiply, indicating more serious issues.

Vertical Cracks

Vertical cracks run up and down the basement wall. These types of cracks are generally caused by the foundation settling or shrinking over time.

Like hairline cracks, vertical cracks are often not a sign of significant structural damage if they remain stable, are not wider than ¼” and do not expand. They can usually be repaired easily with epoxy or urethane injections, preventing water infiltration and further damage. Additionally, reinforcement of the repair using carbon fiber may be a prudent idea.

Horizontal Cracks and Diagonal cracks

Compared to foundation cracks we’ve discussed, horizontal cracks or diagonal cracks are more concerning. Their presence can indicate pressure being exerted on the wall from outside. 

These types of cracks are typically a byproduct of soil expansion or heavy loads being placed near the foundation wall. Addressing these cracks promptly is crucial to avoid potential wall failure. 

Stair-Step Cracks

Stair-step cracks typically appear in masonry walls. The formation of stair-step cracks suggests differential settling in the foundation. This type of crack may require a more thorough investigation to determine the underlying cause and appropriate repair method. 

Common Causes of Foundation Cracks in St. Louis

Foundation crack repair in St. Louis, is a common necessity for many homeowners. There are various reasons why these issues arise. Addressing these concerns promptly can prevent minor cracks from becoming severe structural problems, ensuring the longevity and safety of your home.

Soil Settlement

One of the primary causes of foundation cracks in St. Louis, is soil movement and settlement. Over time, the ground beneath your home can shift due to changes in moisture levels, leading to uneven foundation support. 

This can cause parts of your home to settle more than others, resulting in cracks. It’s vital to monitor such changes and consider solutions like proper grading or installing pier systems to offer better support to your foundation.


Extreme weather conditions also play a significant role in foundation integrity. St. Louis experiences a range of weather, from intense heat in the summer to freezing temperatures in the winter. 

These extremes can cause the soil to expand and contract significantly, putting pressure on your foundation walls. Understanding the impact of weather on your foundation and taking preventive measures, such as ensuring adequate water drainage away from your home, can mitigate these effects.

Poor Drainage

Improper drainage is another critical factor that can lead to foundation problems. Water pooling around your home’s foundation can erode the soil and increase hydrostatic pressure against the foundation walls, leading to cracks. 

Ensuring that your property has effective drainage systems, including gutters and downspouts that direct water away from your home, is essential in protecting your foundation from water-related damage.

Improper Construction

Lastly, poor construction practices can also be at the root of foundation issues. This includes the use of substandard materials, inadequate site preparation, or failure to consider the local soil conditions during construction. 

St. Louis homeowners facing foundation troubles due to such practices may need to seek professional repair services that can address these foundational flaws with long-term, durable solutions. Recognizing these potential causes and taking proactive steps can significantly contribute to maintaining the structural health of your home in St. Louis.

How to Get Foundation Cracks Repaired in St. Louis 

In St. Louis, residents have the benefit of choosing from a myriad of foundation crack repair solutions, catering to the diverse needs that different types of cracks present. Whether it’s the application of epoxy or polyurethane injections for minor hairline cracks, the use of carbon fiber strips to fortify walls against further bowing, or more extensive bracing using steel soldier beams or tieback wall anchors to address serious  issues, there’s a technique for every scenario. 

Each method is designed with a specific problem in mind, ensuring effective and lasting results. However, foundation repair is delicate work. Attempting a DIY fix without the necessary expertise can inadvertently exacerbate the issue, leading to more significant damage and higher costs down the line.
