What Causes Cracks in Basement Floors and How Can You Stop Them?

What Are Basement Floor Cracks?

Basement floor cracks refer to the fissures that develop in the concrete flooring of a basement. These cracks can vary in size, shape, and severity, and they can be an indication of foundation issues. No matter their presentation, it is essential to identify and address these cracks promptly to prevent any further damage to your home’s foundation.

Common Causes of Basement Floor Cracks

Understanding the common causes of basement floor cracks can help homeowners take the necessary preventive measures. Here are some of the primary factors contributing to these cracks: 

Soil Erosion

One of the leading causes of basement floor cracks is soil movement. As your home weathers storms and other inclement weather, the soil beneath your foundation can move causing cracks in your basement floor.

Expansive Soils

Expansive soils, commonly found in nearby regions, have a high clay content that expands when wet and contracts when dry. This constant expansion and contraction can lead to significant pressure on the basement floor, causing cracks to form.

Hydrostatic Pressure

Hydrostatic pressure occurs when water accumulates around your home’s foundation, exerting pressure on the basement floor. This pressure can cause cracks to develop, allowing water to seep into the basement.

Concrete Shrinkage

During the curing process, concrete can shrink slightly, resulting in hairline cracks. While these cracks are generally harmless, they can widen if not addressed promptly. 

Heavy Loads

Excessive weight placed on the basement floor, such as heavy furniture or equipment, can cause stress and lead to cracks. It is essential to distribute weight evenly and avoid placing heavy objects directly on the floor.

How We Address Cracks in Basement Floors

At Mount Valley Foundation Services, we follow a comprehensive approach to repair basement floor cracks and ensure the stability of your home’s foundation. Our process includes:

Comprehensive Inspection 

Our team of experts thoroughly assesses your basement floor cracks, identifying the underlying causes and evaluating the extent of the damage. This inspection helps us determine the most suitable repair solutions for your specific situation. 

Weight Redistribution with Foundation Piers

To address cracks caused by soil movement and expansive soils, we utilize foundation piers to redistribute the weight of your home and stabilize the foundation. These piers are placed deep in the ground to anchor in sturdy, compacted soil. This technique helps prevent further cracks and ensures long-term stability.

In addition to basement floor cracks, we address any wall cracks that may be present, as these issues often appear together. Our range of solutions includes:

Installing Basement Waterproofing Measures

We offer basement waterproofing solutions to prevent water seepage through cracks and protect your basement from moisture. These measures include installing interior drainage systems, sump pumps, and vapor barriers to keep your basement dry and free from water-related issues. 

The Importance of Promptly Addressing Floor Cracks

Promptly addressing basement floor cracks is crucial for several reasons. Ignoring these cracks can lead to the following: 

Further damage to the foundation and structural integrity of your home  

When a cracked or damaged foundation is left unrepaired, it can further deteriorate your home’s structural integrity. The foundation is responsible for supporting the weight of your house and distributing it evenly. If there are existing cracks or damage, they can worsen over time, especially if there are fluctuations in the soil moisture levels or the occurrence of freeze-thaw cycles. This can make the foundation weaker and more vulnerable to structural issues such as settling, shifting, or even collapsing.

Increased risk of water intrusion and basement flooding

A damaged foundation can create pathways for water to enter your home, increasing the risk of water intrusion and basement flooding. Cracks in the foundation walls or floors can allow water from the surrounding soil or heavy rainfall to seep into your basement. This can cause significant damage to your belongings and create an environment prone to mold and mildew growth. Water intrusion can also compromise the stability of the foundation, as excessive moisture can weaken the materials and lead to further deterioration. 

Decreased property value and potential difficulty in selling your home

A damaged foundation can hurt the value of your property. Potential buyers may view foundation issues as a significant red flag, indicating potential structural problems and costly repairs. Even if you sell your home, you may be forced to significantly lower your asking price to account for the necessary repairs. Additionally, some buyers may be deterred from purchasing a home with foundation issues altogether, resulting in a smaller pool of potential buyers and a potentially longer time on the market.

Can I prevent basement floor cracks from occurring?

While it may not be possible to completely prevent basement floor cracks from occurring, there are steps you can take to minimize the risk. One of the most important preventive measures is to ensure proper drainage around your home. This includes maintaining gutters and downspouts to direct water away from the foundation, as well as ensuring the grading around the house slopes away from the foundation. This helps to prevent excess water from seeping into the soil and causing the foundation to shift or settle.
