Noticing your driveway looking uneven or lower than it used to be can be frustrating and concerning. A sinking driveway is not just a cosmetic issue — it often signals deeper problems beneath the surface that can worsen over time if ignored. For homeowners in Louisiana, soil conditions and moisture play a major role in concrete settlement, making this a common issue. At PolyCo Spray Foam, we specialize in identifying the causes of driveway settlement and providing long-lasting solutions through concrete lifting in baton rouge that restore safety, function, and curb appeal.
The Most Common Reasons Driveways Sink
Your driveway relies on stable soil to stay level. When that support weakens, concrete begins to drop. One of the primary causes is soil erosion. Heavy rainfall, poor drainage, or water flowing beneath the slab can wash away the soil that once supported the concrete. As voids form underneath, the slab has nothing to hold it up, and sinking begins gradually.
Another major factor is poor soil compaction during installation. If the ground beneath the driveway was not compacted properly before the concrete was poured, the soil may slowly compress under the weight of vehicles and daily use. Over time, this compression leads to uneven surfaces and noticeable dips in the concrete.
In some cases, expansive clay soils, which are common in Louisiana, can also contribute to driveway settlement. These soils expand when wet and shrink when dry, creating movement beneath the slab that causes concrete to shift and sink unpredictably.
How Water Makes the Problem Worse
Water is one of the most damaging elements when it comes to concrete stability. When rainwater or runoff is not directed away from the driveway, it seeps into the ground and weakens the supporting soil. This is especially common near downspouts, poor grading areas, or cracks that allow water to travel below the slab.
Standing water on or around a driveway is often an early warning sign. If water consistently pools near low spots, it increases erosion and accelerates sinking. Over time, the problem compounds, leading to more severe settlement and potential cracking in the concrete itself.
Why Ignoring a Sinking Driveway Is Risky

A sinking concrete driveway may seem minor at first, but delaying repairs can lead to bigger and more expensive issues. Uneven slabs create trip hazards, damage vehicle suspensions, and allow more water to penetrate beneath the concrete. As settlement continues, cracks may form, reducing the structural integrity of the driveway and shortening its lifespan.
From a property value standpoint, visible concrete issues can negatively affect curb appeal. A driveway is one of the first things people notice, and an uneven surface can give the impression of poor maintenance even if the rest of the home is well cared for.
Why Concrete Lifting Is the Smart Solution
Instead of removing and replacing an entire driveway, many homeowners are turning to concrete lifting in baton rouge as a more efficient solution. Modern concrete lifting uses high-density polyurethane foam to address the root cause of the problem rather than just the surface symptoms.
The foam is injected beneath the slab through small holes and expands to fill voids, lifting the concrete back to its proper level. Because the material is lightweight and water-resistant, it stabilizes the soil without adding excess pressure. This method is precise, fast, and far less disruptive than traditional replacement methods.
Concrete lifting also preserves your existing driveway, saving time and money while delivering long-term results. In most cases, the driveway can be used again the same day, making it a practical choice for busy homeowners.
How PolyCo Spray Foam Fixes Sinking Driveways
At PolyCo Spray Foam, we take a detailed approach to every driveway repair. Our process begins with an evaluation to determine why the driveway is sinking and where the voids are located. Once identified, small access points are created in the concrete, and polyurethane foam is injected beneath the slab.
As the foam expands, it lifts and levels the driveway while reinforcing the soil below. After the foam cures, the access points are patched, leaving a smooth, stable surface. This method ensures the driveway is not only level but also properly supported to prevent future settlement.
Conclusion
If you’re wondering, “Why is my driveway starting to sink?”, the answer almost always lies beneath the surface. Soil erosion, moisture issues, and poor compaction can quietly undermine your concrete until visible damage appears. The good news is that professional concrete lifting in baton rouge offers a reliable, cost-effective way to restore your driveway without replacement.
