At SERVPRO®, we are no stranger to the damage that foundation cracks and water infiltration can cause. These issues can compromise the structural integrity of your home, leading to costly repairs if not addressed promptly. In this blog, we’ll explore the causes of foundation cracks, how water infiltration occurs, and the steps you can take to fix these problems.

Common Causes of Foundation Cracks

Foundation cracks can appear for several reasons, and understanding the cause is crucial for finding the right solution. One of the most common causes is the natural settling of the ground beneath your home. As the soil shifts over time, it can put pressure on the foundation, leading to cracks.

Another frequent cause is poor drainage around your property. If water doesn’t drain away from your home properly, it can accumulate around the foundation, exerting pressure and eventually causing cracks. Additionally, seasonal changes, such as freezing and thawing cycles, can lead to the expansion and contraction of soil, further contributing to foundation damage.

Tree roots are another potential culprit. If large trees are planted too close to your home, their roots can grow underneath the foundation, disturbing the soil and leading to cracks. Lastly, improper construction or the use of low-quality materials during the building process can result in a weaker foundation that is more prone to cracking.

How Water Infiltration Occurs

Water infiltration typically happens through cracks in your foundation. When rainwater or groundwater accumulates around the foundation, it can seep into these cracks, leading to water damage in your basement or crawl space. Over time, this can result in mold growth, damage to personal belongings, and even further weakening of the foundation.

Poor drainage systems, such as clogged gutters or downspouts that don’t direct water away from your home, can exacerbate the problem. Additionally, high water tables or flooding in your area can increase the likelihood of water infiltration.

Fixing Foundation Cracks and Water Infiltration

Addressing foundation cracks and water infiltration requires a combination of repairs and preventive measures. First, it’s essential to identify the type and severity of the cracks. Hairline cracks may not be a cause for concern, but larger cracks or those that are widening over time should be evaluated by a professional.

To repair foundation cracks, various methods can be employed, such as epoxy injections or polyurethane foam. These materials are injected into the cracks, sealing them from the inside and preventing further water infiltration.

Preventing water infiltration involves ensuring proper drainage around your home. This can include extending downspouts, installing a French drain, or regrading the soil around your foundation to direct water away from the structure. Additionally, waterproofing your basement walls or installing a sump pump can provide extra protection against water damage.
