Let’s get started!
What Are Slab Lifting And Leveling Services?
Slab lifting and leveling fix uneven or sinking concrete in your home or yard. These services restore safety and appearance by raising and stabilizing the concrete. Different slabs may have unique problems that need specific solutions.
Common Problems With Uneven Concrete
Uneven concrete isn’t just unattractive, it’s a warning sign of deeper foundation or soil issues. Here are some of the most common problems you might notice:
- Cracks in Slabs: Visible cracks across driveways, patios, or floors often signal soil movement or pressure beneath the concrete.
- Dips and Low Spots: Uneven areas collect water, creating hazards and speeding up deterioration.
- Sinking Sections: Large slab areas may sink when soil underneath erodes, weakens, or compacts.
- Soil Erosion: Water washing away soil leaves empty voids beneath slabs, causing instability.
- Heavy Loads or Poor Installation: Excess weight or improper construction can trigger early settling and damage.
- Moisture and Temperature Changes: Water softens soil, while hot and cold cycles expand and contract the ground, shifting slabs out of place.
These problems never fix themselves; if ignored, they only worsen and cost more to repair later.
Types Of Slabs That Need Leveling
Concrete slabs come in many forms, and different types often need lifting or leveling. Common examples include:
- Driveways and sidewalks
- Garage floors
- Patios and pool decks
- Basement floors and porches
Each slab type has its own risks. For instance, pool decks must be level to avoid water pooling, and driveways need to support heavy vehicles without cracking.
Benefits Of Hiring Slab Lifting And Leveling Experts
Fixing sinking or uneven concrete slabs requires skill and the right tools. Choosing experienced professionals makes the process safer, faster, and more cost-effective for you.
Enhanced Safety And Curb Appeal
Uneven slabs can create tripping hazards around your home. Experts level the concrete, reducing the chance of falls.
Leveling your slabs also improves the appearance of your property. Smooth, even surfaces make your yard or driveway neater and more inviting, adding value and giving a good impression to guests or buyers.
Professionals use materials like polyurethane foam that won’t damage nearby landscaping. They also avoid heavy demolition, so there’s less mess and less risk of accidents on your property.
Cost-Effective Solutions For Homeowners
Repairing slabs early saves you money by stopping damage from getting worse. Professionals find the problem spots and lift the concrete with minimal disturbance.
Using slab lifting instead of replacing concrete cuts down labor and material costs. Our experts rely on proven foam lifting techniques to quickly restore slabs without breaking up the entire area.
Once your slabs are level and stable, they resist sinking and cracking longer. This means fewer repairs and maintenance bills over time.
Methods Used By Slab Lifting Specialists
Slab lifting experts use different methods to raise and level sinking concrete. These methods vary in materials, process, and longevity. Knowing your options helps you decide what best fits your needs.
Mudjacking Technique
Mudjacking uses a mixture of water, soil, and cement called slurry.
The specialist pumps this slurry under the sunken slab through small holes. This pushes the slab back to its original position.
The slurry fills voids under the concrete and hardens to provide support. Mudjacking works well for larger slabs and areas with easy soil access. It’s usually less expensive but can take longer to dry. This method is suitable for fixing surface problems without full replacement.
However, it’s less precise than newer techniques and might not suit all soil types.
Polyurethane Foam Injection
Polyurethane foam injection is a newer way to lift slabs.
Experts inject a lightweight, expanding foam beneath the concrete.
The foam fills empty spaces and pushes the slab up evenly. It hardens fast, often in minutes, allowing quicker project completion. This foam also resists water and soil movement, making it durable.
Because it weighs less than slurry, it works well on weak soils. Since this method uses smaller injection points, you will see fewer drilling holes, which reduces the damage to the concrete during repair.
Comparing Repair Methods
| Feature | Mudjacking | Polyurethane Foam Injection |
|---|---|---|
| Material | Cement slurry (mud) | Expanding polyurethane foam |
| Drying Time | Several hours to days | Minutes |
| Weight | Heavier | Lightweight |
| Precision | Moderate | High |
| Cost | Usually lower | Typically higher |
| Soil Suitability | Best on stable soils | Good on weak or shifting soils |
| Surface Damage | Larger holes needed | Smaller holes, less invasive |
Picking the right method depends on your budget, soil type, and how quickly you want the work done. Experts like those at Helicon can guide you to the best choice for your slab lifting needs.
Slab Lifting vs. Slab Replacement: Which Is Better?
When your concrete slab sinks, you might wonder: Should you lift it or replace it completely?
Both options solve uneven concrete, but they differ greatly in cost, time, and long-term results. Here’s a quick comparison:
| Factor | Slab Lifting (Polyurethane Foam) | Full Slab Replacement |
| Cost | Starts in the few-thousand-dollar range depending on slab size | Higher overall, includes demolition, disposal, and new concrete |
| Timeframe | Completed in hours, ready to use in 15–30 minutes | Can take several days to weeks, curing time required |
| Disruption | Minimal—small drill holes, no heavy demolition | Major disruption—removal, heavy equipment, landscaping damage |
| Durability | Foam resists water, stabilizes soil, and lasts for decades | New slabs may sink again if soil issues aren’t fixed |
| Environmental Impact | Uses less material, lightweight, non-invasive | More waste from broken concrete and new materials |
In most cases, slab lifting with polyurethane foam is faster, cleaner, and more cost-effective than replacement—especially in Florida’s sandy soils. Our experts guide you to the best option based on your specific situation.
