Driveway Leveling in Alabama & Tennessee — Lift Sunken Concrete With Poly Rise, Ready in 15 Minutes, Free Estimates

Request Your Free Estimate

Driveway leveling in Alabama and Tennessee does not have to mean tearing out your concrete and starting over. When a driveway sinks, settles, or becomes uneven, the concrete itself is almost always still structurally sound — the problem is the soil underneath. The Crack Guys lift sunken driveways using Poly Rise, our two-part polyurethane foam injection system that fills voids beneath the slab, raises it back to its original level, and is ready to drive on in just 15 minutes. It costs a fraction of replacement, leaves no mess, and is backed by a lifetime transferable warranty and free estimates across Alabama and Tennessee.

Why Driveways Sink in Alabama and Tennessee

A sinking driveway is almost never a concrete problem — it is a soil problem. The concrete slab is only as stable as the ground beneath it, and in Alabama and Tennessee, that ground is working against you in several ways:

• Expansive clay soils — Much of Alabama and Tennessee sits on clay-heavy soil that swells when wet and shrinks when dry. This seasonal cycle creates a constant push-pull movement beneath the slab that gradually causes settlement and cracking.
• Soil erosion — Heavy rainfall — over 58 inches per year in Alabama, over 52 in Tennessee — washes fine soil particles away from beneath the slab over time, creating voids that the concrete eventually sinks into.
• Poor original compaction — Many driveways were poured over soil that was not properly compacted during construction. As that loose soil settles under the weight of vehicles over the years, the slab settles with it.
• Tree root activity — Tree roots growing beneath a driveway slab displace soil, create voids, and can cause the slab to heave in some areas while sinking in others.
• Heavy loads — Trucks, trailers, RVs, and other heavy vehicles concentrated on specific areas of the driveway accelerate soil compaction and settlement in those spots.

Why a Sunken Driveway Is More Than a Cosmetic Problem

• Trip and fall hazard — Even a half-inch lip between two concrete slabs is enough to cause a serious trip and fall. Homeowners can be liable for injuries to guests, delivery drivers, and visitors caused by an uneven driveway.
• Vehicle damage — Driving over a sunken section of driveway repeatedly stresses vehicle suspensions, tires, and undercarriages. Low-clearance vehicles can scrape on raised edges or sunken sections.
• Water drainage problems — A level driveway sheds water away from the home. A sunken driveway pools water — directing it toward the foundation and potentially contributing to basement or crawl space moisture problems.
• Accelerating damage — A small void beneath a driveway slab grows larger every time it rains. The longer a sunken section is left unaddressed, the more the void expands and the more the slab deteriorates.
• Curb appeal and home value — A sunken, cracked driveway is one of the first things a buyer or home inspector notices. Addressing it before listing is one of the highest-return cosmetic improvements a homeowner can make.

Our Poly Rise Driveway Leveling Process

The Crack Guys lift sunken driveways using Poly Rise — our two-part polyurethane foam injection system. Here is exactly how it works:

1. Assessment: Our technician evaluates the sunken sections, identifies the void locations beneath the slab, and marks the injection points. Small 5/8-inch holes are drilled at strategic locations — far smaller and less disruptive than the large holes required by traditional mudjacking.
2. Foam injection: The two-part Poly Rise polyurethane foam is injected through the holes. The foam expands immediately upon injection, filling voids beneath the slab and applying lifting pressure from below.
3. Precision leveling: Our technician monitors the lift in real time, adjusting the injection to raise the slab precisely to the correct level — stopping at the right height rather than over-lifting.
4. Hole sealing: The small injection holes are filled and sealed, leaving the driveway clean and nearly invisible from the surface.
5. Ready in 15 minutes: Unlike replacement concrete that takes days or weeks to cure, Poly Rise reaches full strength within 15 minutes of injection. You can drive on your driveway the same day — often within the hour.

Poly Rise vs. Mudjacking vs. Replacement

Replacement — tearing out and repaving an entire driveway — is typically 3 to 5 times more expensive than Poly Rise leveling and produces the same result: a level driveway over the same soil that caused the original settlement. Without addressing the void beneath, a replacement slab will often begin settling again within a few years. Poly Rise fills the void that caused the problem, providing a more permanent fix to the underlying issue.

Signs Your Driveway Needs Leveling

• Visible gaps or lips between driveway slabs
• One or more sections of the driveway noticeably lower than surrounding slabs
• Water pooling on the driveway surface rather than draining away
• Cracks running across the surface of the slab
• A hollow sound when you tap the slab with your foot — indicating a void beneath
• The driveway apron has separated from or sunk below the garage threshold
• Vehicle scraping or bottoming out when entering or exiting the driveway

Frequently Asked Questions — Driveway Leveling

How much does driveway leveling cost compared to replacement?

Poly Rise driveway leveling typically costs 50 to 70 percent less than full driveway replacement. The exact savings depend on the size of the sunken area, the depth of the void beneath the slab, and the number of injection points required. The Crack Guys provide free, no-obligation estimates so you know the exact cost before any work begins.

How long does Poly Rise driveway leveling last?

Poly Rise polyurethane foam is waterproof, does not erode, and does not break down over time. It fills the void beneath the slab permanently, providing a durable long-term fix. All Poly Rise installations are backed by The Crack Guys’ lifetime transferable warranty.

Can all sunken driveways be leveled with foam injection?

Most sunken driveways can be leveled with Poly Rise as long as the concrete slab itself is structurally intact — meaning it has not shattered into fragments too small to lift as a unit. If a slab section is smaller than approximately 3 square feet or has deteriorated beyond repair, that section may need to be replaced rather than lifted. Our inspector will evaluate the slab condition during the free estimate and give you an honest assessment of what can be leveled versus what needs replacement.

How is Poly Rise different from mudjacking?

Mudjacking uses a heavy slurry of soil, water, and cement injected through large 2 to 3 inch holes. The material is heavy, can wash out over time, requires large visible patches, and has a 24 to 48 hour cure time. Poly Rise uses lightweight polyurethane foam injected through 5/8 inch holes, is waterproof and permanent, leaves nearly invisible patches, and is ready to use in 15 minutes. Poly Rise also does not add significant weight to the soil beneath the slab — an advantage in areas with weak or unstable soil.

Will my driveway sink again after leveling?

Poly Rise fills the existing voids and stabilizes the slab. However, if the underlying soil conditions that created the void — poor drainage, expansive clay, erosion — are not addressed, new voids can potentially develop elsewhere over time. Our inspector will identify any contributing drainage or grading issues during the free estimate and advise on any additional steps that would extend the life of the repair.

How long does driveway leveling take?

Most residential driveway leveling jobs are completed in a few hours. The driveway is ready to use within 15 minutes of injection completion — the same day in almost every case.

Do I need to do anything to prepare my driveway before the appointment?

Clear vehicles and other items from the driveway on the day of service. Our team handles all preparation, drilling, injection, and cleanup. The job site will be left clean with the injection holes patched before the crew departs.
