Slab Jacking

Slab jacking is a reliable and effective technique commonly employed for concrete leveling. It involves injecting a specialized grout mixture beneath concrete slabs that have settled, cracked, or become uneven.

Benefits of Slab Jacking

• Restores Surface Level: Slab jacking can elevate sunken concrete slabs, restoring their level and functionality.
• Eliminates Trip Hazards: By leveling concrete surfaces, slab jacking minimizes the risk of tripping and falling accidents.
• Improves Drainage: Restored surfaces enhance water drainage, preventing pooling and reducing erosion.
• Extends Concrete Life: Leveling concrete slabs prevents further damage, extending their lifespan.
• Cost-Effective: Slab jacking is often more economical than replacing entire concrete slabs.

How Slab Jacking Works

Slab jacking involves the following steps:

1. Access Holes: Small access holes are drilled through the concrete surface.
2. Grout Injection: A specialized grout mixture is pumped through the access holes beneath the sunken slab.
3. Lifting: The grout fills the void beneath the slab, gradually lifting it back to its original level.
4. Hole Filling: Once the slab is level, the access holes are filled with a permanent filler.

Applications of Slab Jacking

Slab jacking can be used for various concrete leveling applications, including:

• Driveways: Elevating driveways that have settled or cracked.
• Walkways: Leveling walkways to improve safety and aesthetics.
• Patios: Restoring the level of patios that have become uneven or sunken.
• Garage Floors: Leveling garage floors to ensure proper drainage and vehicle movement.
• Industrial Floors: Maintaining the level of industrial floors, such as in warehouses and factories.

Factors to Consider

When considering slab jacking, it’s essential to consider factors such as:

1. Concrete Thickness: Slab jacking is ideal for thinner concrete slabs up to 8 inches.
2. Condition of the Concrete: If the concrete is severely damaged or cracked, slab jacking may not be the best solution.
3. Site Conditions: Accessibility to the area and the availability of equipment are crucial factors to consider.
