A beautiful, level driveway is essential for your home’s curb appeal and safety. But if you live in the Baton Rouge area, you might have noticed sections of your concrete slabs starting to tilt, sink, or lift.
This common issue is more than just an eyesore; it’s a serious sign of underlying soil problems that demand immediate attention. Ignoring a rising or sinking driveway can lead to costly damage to your foundation, create dangerous tripping hazards for your family and visitors, and ultimately reduce the value of your property. Fortunately, solving this problem doesn’t always require the expensive and disruptive process of full concrete replacement.
As the leading experts in polyurethane solutions, PolyCo Spray Foam is here to explain exactly why your driveway is lifting and how we provide a permanent, cost-effective fix right here in Louisiana. Understanding the root cause is the first critical step to restoring the stability and longevity of your home’s pavement. We specialize in identifying and correcting the core issues that plague concrete structures throughout the region, ensuring that when you invest in a repair, it’s one that lasts.
The Root Causes of Concrete Movement and Deterioration
Concrete slabs are incredibly heavy, and they rely entirely on the soil beneath them for stable, uniform support. When that support system fails, the concrete is certain to move, resulting in the lifting, sinking, and cracking that homeowners observe. The primary culprit in our region is often moisture and the dynamics of the underlying soil. Louisiana’s soil composition, particularly the expansive clay that is common here, is notorious for changing volume drastically as moisture levels fluctuate.
During heavy rains or periods of poor drainage, this clay can swell, exerting immense upward pressure and pushing sections of concrete up, which creates the “lifting” you are seeing. Conversely, drought conditions or drainage issues can cause soil erosion and compaction, creating voids (empty spaces) beneath the slab. When a void forms, the massive weight of the concrete slab is no longer evenly distributed, causing it to fracture and sink into the open space.
Poorly compacted fill soil when the home or driveway was originally built is another common and major cause; the soil simply settles over time under the load, leaving gaps. Additionally, aggressive tree roots seeking moisture can grow directly under the concrete, exerting powerful pressure that results in localized lifting and cracking.
Addressing these underlying soil issues is paramount to achieving a long-lasting repair, which is precisely why PolyCo specializes in stabilizing the entire system, not just patching the symptoms. This comprehensive approach ensures the structural integrity of your driveway for years to come by addressing the very foundation of the problem.
Recognizing the Signs of a Sinking Slab
It’s vital to identify concrete issues early before they escalate into severe structural problems or become a liability risk. The most obvious and common sign is a noticeable height difference between adjacent slabs, which creates a significant tripping hazard for anyone using the area.
Look closely at areas where the driveway meets the garage floor or a nearby sidewalk—any offset or lip here indicates severe settlement or movement. Another key indicator is water pooling. If you notice large puddles forming on your driveway after a rain shower, it means the slab has settled and is no longer sloping correctly toward drainage areas.
This standing water not only makes your driveway unusable but can worsen the problem by introducing more moisture to the unstable soil underneath, accelerating erosion. Cracks, especially those running corner-to-corner or forming a network (often called spiderweb or alligator cracking), are the concrete’s cry for help, signaling stress from inadequate support.
You may also notice gaps appearing between the concrete and the soil or along the edge of the driveway. If you observe these telltale signs, you need to act quickly and decisively. Delaying the repair allows the underlying soil conditions to deteriorate further, potentially leading to more extensive and costly repairs down the road, possibly requiring full replacement. Addressing the issue immediately protects your investment and ensures the absolute safety of your property.
The Superior Solution: Polyurethane Concrete Lifting
When your driveway lifts or sinks, you typically have three options: tear out and replace, traditional mudjacking, or modern polyurethane foam injection. Tearing out and replacing is expensive, takes days, generates a massive amount of waste, and leaves you with the risk that the new slab will also sink for the same underlying reasons.
Mudjacking uses a heavy, messy cement-based slurry that can place too much stress on the already compromised soil and takes longer to cure. The definitive and modern answer PolyCo Spray Foam offers is polyurethane foam jacking, a cutting-edge technique that is transforming concrete repair across the industry. This process is incredibly efficient and minimally invasive, requiring only small, penny-sized holes drilled strategically into the concrete slab.
We then inject a high-density, lightweight polyurethane foam beneath the slab. As the foam expands, it fills any voids, compacts the unstable soil, and gently yet powerfully raises and stabilizes the concrete back to its original, level position. This foam cures rapidly—often in under an hour—allowing you to use your driveway the very same day.
Unlike traditional methods, our polyurethane solution is environmentally friendly, waterproof, and will not erode or decompose over time, providing a permanent solution that stabilizes the sub-base and secures the slab’s position. It is the best choice for homeowners seeking a fast, clean, and durable repair that truly addresses the cause of concrete failure.
