Sinking Concrete Slab
The overall stability of a home is paramount, and ensuring the concrete slabs are stable is a crucial part of this. Concrete is a robust material commonly used in various home structures, yet it isn’t invulnerable to damage.
A sinking concrete slab, whether it’s in your driveway, walkway, patio, or inside your home, is an issue that goes beyond aesthetics; it’s a safety concern and indicative of deeper soil-related problems that could jeopardize your foundation if not addressed timely.
At AFS, we acknowledge the challenges homeowners face with sinking concrete slabs, both outdoors and indoors. We offer extensive, reliable concrete lifting solutions designed to fix these issues, thereby enhancing the safety and visual appeal of your property.
On this page, we delve into the reasons behind the occurrence of sinking concrete slabs, their effects on your property, and how AFS’s unique concrete lifting solutions and additional services can benefit you.
What Is a Sinking Concrete Slab?
A sinking concrete slab occurs when a concrete surface starts to descend unevenly, leading to visible dips or cracks. This condition not only diminishes the visual appeal of your home but also introduces safety hazards due to the potential for trips and falls.
Numerous concrete structures are susceptible to sinking, including:
In addition to sinking, concrete slabs may also display other types of damage, such as:
Early detection and intervention are vital in preventing further damage, minimizing risks, and restoring the appearance and functionality of the affected area. That’s why it’s essential to reach out to local concrete repair specialists like AFS at the first sign of any damage.
What Causes a Sinking Concrete Slab?
Various factors can contribute to a sinking concrete slab:
- Soil Settlement: Over time, the soil beneath a concrete slab naturally settles and compacts, leading to sinking. This is particularly common when fill dirt is not adequately compacted, and it can become pronounced during dry periods.
- Soil Erosion: Problems with water drainage, leaks, or shifting soil can lead to soil erosion underneath concrete, removing its stable base and causing sinking.
- Excessive Moisture: Soil that becomes overly saturated due to rain, or flooding can shift, destabilizing the concrete slab. Prolonged exposure to moisture can also lead to soil erosion and weakening.
- Inadequate Drainage: Malfunctioning drainage systems such as gutters and downspouts can lead to water accumulation around concrete areas, contributing to soil issues underneath.
- Tree Root Growth: The growth of tree roots can displace soil and lift or crack concrete slabs. As roots decay, they can create voids in the soil, contributing to sinking.
- Freeze-Thaw Cycles: The expansion and contraction of soil due to freezing and thawing can stress and shift the soil beneath concrete slabs.
- Installation Errors: Mistakes made during the preparation of the site, base compaction, and concrete curing and pouring processes can lead to future sinking and cracking.
Promptly addressing these underlying issues is crucial to prevent further structural damage to your home’s foundation.
Can You Fix a Sinking Concrete Slab?
Yes, it is both possible and critical to fix a sinking concrete slab. Identifying and repairing the slab early on is essential, as delaying repairs can limit your options and lead to further damage.
The optimal long-term solution requires accurately identifying and addressing the underlying cause. Simple fixes like mudjacking or filling the gap beneath the slab with gravel might provide a temporary solution but could result in further sinking over time.
A comprehensive approach is necessary for lasting repair and prevention. By addressing all underlying causes and using advanced techniques and products, AFS ensures optimal results, safeguarding against future issues.
We utilize PolyRenewal™, an advanced polyurethane injection system, to lift and stabilize sinking exterior concrete slabs. For foundational issues, we employ various foundation piers, including slab piers, to permanently stabilize and potentially lift your settling foundation.
Every home has unique repair needs, and AFS is here to help determine the best solution for your property. Reach out to our team today to get started.
How to Fix a Sinking Concrete Slab
AFS employs a meticulous process when using PolyRenewal™ to lift sunken concrete slabs:

- Install ports into the drilled holes for injection.
- Prepare the proprietary closed-cell polyurethane foam.
- Inject the foam underneath the concrete slab.
- Allow the foam to expand, filling the void and lifting the concrete.
- Wait for the foam to cure (this typically takes about 15 minutes).
- Remove the injection ports.
- Fill and smooth over the drilled holes.
- Seal any cracks and joints to prevent future damage.
- Conduct regular inspections and maintenance to ensure lasting protection.
AFS’s unique products are tailored to effectively address your specific issues, providing a level of quality and durability that generic solutions can’t match.
Why Address a Sinking Concrete Slab Now
Addressing a sinking concrete slab with a professional inspection and repair is vital for several reasons:
- Safety: Sunken and uneven slabs pose significant tripping and falling hazards, especially for seniors, young children, and anyone with mobility challenges.
- Continuous Movement: Without proper repairs, slabs will persist in shifting and sinking, exacerbating the problem.
- Structural Damage: Soil issues leading to sinking slabs can also impact walls and foundations if not dealt with promptly.
- Water Problems: Sunken slabs can lead to water pooling and seeping under foundations, resulting in moisture damage, mold growth, and foundation cracks. Outside, pooling water can cause drainage issues, flooding, and attract pests.
- Appearance and Home Value: Damaged and uneven slabs detract from a property’s curb appeal and can deter potential buyers.
AFS provides essential solutions to fully resolve these issues, ensuring that our products deliver superior, lasting results compared to standard options.
