What to do About Cracks on a Garage Floor
Garage floor cracks may not initially cause concern, but neglecting them can result in significant and expensive problems. At AFS, we understand the vital role of a sturdy and functional garage floor, so we specialize in identifying, diagnosing, and addressing damage using proven concrete solutions.
This guide explains what you need to know about garage floor cracks and offers insights into repairing them to prevent further damage.
What Are Garage Floor Cracks?
Garage floor cracks develop gradually, appearing as separations in the concrete slab. Many factors, including natural shrinkage during curing, fluctuations in temperature, or movement in the underlying soil, cause these cracks. Inadequate drainage systems can sometimes exacerbate crack formation by allowing water to accumulate around the foundation. While some cracks may be hairline and purely cosmetic, others may be wider and indicate underlying foundation issues.
Types of Concrete Cracks
There are several types of cracks, each originating from different causes. These are a few common types of concrete cracks:
Foundation Cracks
Foundation cracks often parallel foundation walls and may indicate significant structural issues. These cracks may develop due to soil settlement, hydrostatic pressure, or structural deficiencies.
Cracks Caused by Concrete Shrinkage
Concrete can naturally contract during the curing process, resulting in shrinkage cracks. These cracks are typically narrow and appear randomly across the surface of the concrete slab.
Cracks Caused by Improper Initial Concrete Installation
Improper concrete mixing, poorly compacted soil, and insufficient cure times after initial concrete installation can cause cracks. These issues indicate poor initial construction practices. Consult with a concrete expert to ensure proper installation.
Weather-Related Cracks
Extreme temperature changes, freeze-thaw cycles, and exposure to deicing salts can cause cracks over time, especially in older garage floors. Regular maintenance and protective measures help prevent weather-related damage.
Reasons to Repair Cracks on a Garage Floor
Concrete cracks can create safety risks, especially in high-traffic areas where they can cause trips and falls. If left unrepaired, cracks can worsen over time, potentially compromising the structural integrity of your garage floor and the surrounding areas. They also allow water to seep in, which can lead to moisture issues like mold growth and further damage.
In addition to these concerns, a cracked and uneven garage floor can negatively impact your property’s appearance and decrease its value. Cracks also provide entry points for pests such as insects and rodents, increasing the likelihood of infestations.
Addressing and repairing garage floor cracks is essential for maintaining a safe, structurally sound, and visually appealing home.
How to Fix Cracks in Your Garage Floor
Repairing garage floor cracks is essential to prevent worsening damage. While DIY crack sealants and repairs may seem like the solution, they often fail to address the root cause of the problem, potentially worsening the damage. AFS permanently repairs and lifts concrete and prevents future occurrences using tailored and proven methods.
PolyRenewal™ Polyurethane Concrete Lifting
PolyRenewal™ concrete lifting is an advanced repair method that addresses the underlying problems that cause cracks, like unstable soil. This technique involves injecting a lightweight, durable polyurethane foam beneath the concrete to fill voids and lift and restore concrete slabs to their original level. PolyRenewal™ is an eco-friendly foam injection that cures in 15 minutes, providing a robust and stable base and preventing further settlement and cracking.
Install Waterproofing Systems
When moisture contributes to cracks, implementing waterproofing measures becomes crucial. This approach may involve installing interior drainage systems and sump pumps and ensuring proper landscape grading around the garage to redirect water away from the foundation.
Establish Proper Drainage
Inadequate drainage can result in soil erosion and ground settlement, causing cracks in the garage floor. To prevent these issues, it’s crucial to maintain proper grading around the garage and ensure downspouts and drainage systems are functioning properly.
PolyRenewal™ Injection for Garage Floor Repair
PolyRenewal™addresses cracks in garage floors and other concrete issues. The repair process begins with a free inspection by our AFS experts to identify the extent and causes of the cracks. If we determine that PolyRenewal™ is right for your property, we will proceed by drilling small holes into the concrete slab. Polyurethane foam is then injected under the slab, lifting and restoring the concrete to its original level. The curing process takes 15 minutes, minimizing disruption to daily routines and landscaping. Finally, the small holes are sealed to leave a smooth finish. PolyRenewal™ is our patented, permanent repair approach for cracks in garage floors and other surfaces like patios, pool decks, sidewalks, and steps.
