Leveling concrete primarily involves lifting sunken slabs back to their original position, a process often achieved by injecting a specialized compound beneath the concrete. This method, commonly known as concrete lifting or slab jacking, effectively restores the structural integrity and aesthetic appeal of concrete surfaces that have settled over time.
Understanding Concrete Leveling
Concrete surfaces, such as driveways, patios, garage floors, and interior slabs, can settle or sink due to various factors. These include soil erosion, poor compaction during installation, or the presence of voids beneath the slab. When concrete settles, it creates uneven surfaces that can pose trip hazards, lead to water pooling, or even cause further damage to the concrete itself. Concrete leveling addresses these issues by bringing the sunken sections back to an even plane.The Concrete Lifting Process
The most effective and common method for leveling settled concrete involves a precise, non-invasive technique that utilizes specialized compounds. Concrete leveling technicians follow a systematic approach to ensure the slab is lifted uniformly and durably.The process typically unfolds in these key steps:
- Strategic Drilling: Concrete leveling technicians begin by drilling small holes through the concrete slabs in strategic locations. These holes are carefully positioned to provide optimal access for the lifting compound and ensure even distribution.
- Compound Injection: A specialized compound is then pumped through these drilled holes beneath the sunken concrete slab. This compound can be a high-density polyurethane foam or a cementitious slurry, depending on the specific requirements of the project and the type of void being filled.
- Slab Elevation: As the compound is injected, the pressure from the compound causes the slabs to rise back up to the proper, level position. Technicians closely monitor the slab's elevation throughout this process, often using laser levels, to ensure accuracy and prevent over-lifting.
- Hole Sealing: Once the concrete slab has been successfully lifted and leveled, the drill holes are sealed off. This final step secures the compound within the void and provides a smooth, finished surface.
This process is designed to fill voids, stabilize the soil, and provide a solid foundation for the concrete, preventing future settlement.
Key Benefits of Professional Concrete Leveling
Opting for professional concrete leveling offers several advantages over traditional concrete replacement:- Cost-Effective: Leveling is typically more affordable than tearing out and repouring new concrete.
- Time-Efficient: The process is much faster, often completed in a matter of hours, with minimal disruption.
- Less Invasive: It avoids the extensive excavation and demolition associated with concrete replacement.
- Eco-Friendly: It reduces landfill waste by salvaging existing concrete.
- Durable Solution: By filling voids and stabilizing the underlying soil, concrete leveling provides a long-lasting solution to settlement issues.
- Immediate Use: In many cases, the leveled surface can be used almost immediately after the process is complete.
When to Consider Concrete Leveling
You should consider concrete leveling if you notice any of the following issues with your concrete surfaces:- Uneven or sunken sections of driveways, sidewalks, or patios.
- Water pooling on concrete surfaces after rain.
- Cracks in the concrete that indicate underlying settlement.
- Doors or windows sticking due to a sinking foundation slab.
- Trip hazards created by unlevel concrete.
This technique is a reliable solution for restoring stability and functionality to various concrete structures around your property.
Summary of Concrete Leveling Process
| Step | Description | Purpose |
|---|---|---|
| Drilling | Small holes are drilled through the concrete. | To create access points for the compound. |
| Pumping | A specialized compound is injected under the slab. | To fill voids and generate lifting pressure. |
| Lifting | The concrete slab rises to a level position. | To restore the surface's original elevation. |
| Sealing | The drilled holes are sealed. | To finish the repair and protect the slab. |
