Sinking Concrete Slab
Concrete slab stability is crucial for your home’s structural integrity. While concrete is known for its durability, it’s not immune to problems. If you notice a sinking concrete slab in your driveway, sidewalk, porch, or inside your home, it’s more than a cosmetic issue. It’s a safety hazard indicating soil problems that could affect your home’s foundation.
Dry Pro Crawlspace & Foundation Repair understands the challenges homeowners face with sinking concrete slabs, whether they are outdoors or indoors. We offer tailored solutions to address and resolve these issues, improving the safety and appearance of your home.
This page explains why concrete slabs sink, their impact on your home, and how Dry Pro’s concrete lifting services can help.
What Is a Sinking Concrete Slab?
Sinking concrete slabs occur when a concrete surface unevenly lowers, creating noticeable dips or cracks. This affects the appearance of your property and poses safety concerns.
Sinking concrete slabs occur in various places, including:
Sinking concrete slabs can also exhibit other damage, such as:
Identifying and addressing sinking slabs early by a qualified professional can prevent further damage and enhance the usability and aesthetics of the area. If you notice such issues, it’s essential to contact local concrete repair professionals like Dry Pro Crawlspace & Foundation Repair.
What Causes a Sinking Concrete Slab?
Several common factors contribute to a sinking concrete slab:
- Settling Soil: Over time, the soil underneath the slab compacts, causing the concrete above to sink. This often occurs with improperly compacted fill dirt, especially during dry periods.
- Eroding Soil: Water drainage problems, leaks, or shifting soil can erode the soil beneath the concrete, leading to instability and sinking.
- Excessive Precipitation: Saturated soil from rain, floods, or snowmelt can expand and move, creating instability in the slab.
- Poor Drainage: Damaged drainage systems like gutters and downspouts can collect water near the concrete, exacerbating underlying soil issues.
- Tree Roots: Growing tree roots can displace surrounding soil, leading to slab lifting and cracking. As the roots decompose, voids in the soil may cause sinking slabs.
- Freeze-Thaw Cycles: Repeated freezing and thawing of the ground can stress and shift the soil under slabs.
- Installation Problems: Mistakes during site preparation, base compaction, curing, or pouring can result in future sinking and cracking of the concrete.
Promptly addressing these causes is vital to prevent further damage to your home’s foundation.
Can You Fix a Sinking Concrete Slab?
Yes, is it possible to fix a sinking concrete slab, and it is also imperative. It is vital to identify and address the issue promptly, as more severe damage can restrict the available repair options.
The key to a successful repair lies in accurately determining and remedying the root cause of the problem. Merely filling the void beneath the slab with gravel may not result in a lasting solution. A holistic approach is necessary for a long-term fix and prevention. At Dry Pro Crawlspace & Foundation Repair, we utilize cutting-edge methods, such as SettleStop™ PolyRenewal™, to lift sunken exterior concrete slabs. Additionally, for foundational problems, we resort to techniques like foundation piers to stabilize and potentially lift your settling foundation.
