Concrete surfaces, such as driveways, patios, and sidewalks, play a crucial role in both residential and commercial properties. However, these slabs can sometimes sink or become uneven due to various factors. This is where slab jacking, also known as concrete leveling, comes into play. This comprehensive guide will explain what slab jacking is, what causes a concrete slab to move, how concrete leveling is done, why slab jacking is a superior solution, and why working with Slabjack Geotechnical for your concrete leveling needs is a great idea.
What Is Slab Jacking?
Slab jacking, also referred to as concrete lifting or concrete leveling, is a cost-effective method used to raise and stabilize uneven or sunken concrete slabs. This process involves injecting a special material beneath the concrete slab to lift it back to its original position. The technique is widely used for repairing sidewalks, driveways, patios, pool decks, and other concrete surfaces.
What Causes a Concrete Slab to Move?
Concrete slabs can move or sink due to several reasons:
- Soil Erosion: Water drainage issues or heavy rainfall can wash away the soil beneath the concrete, creating voids.
- Poor Soil Compaction: Inadequate soil compaction during the construction phase can lead to settling over time.
- Tree Roots: The growth of tree roots can push up slabs or create voids underneath them.
- Heavy Loads: Excessive weight from vehicles or heavy equipment can cause the soil to compact and the slab to sink.
- Natural Settling: Over time, the natural settling of the soil can lead to uneven surfaces.
How Concrete Leveling Is Done
Concrete leveling through slab jacking is a straightforward yet highly effective process:
- Assessment: The first step involves a thorough inspection of the site to identify the cause and extent of the settlement.
- Drilling Holes: Small holes are drilled into the affected concrete slab at strategic locations.
- Injecting Material: A specialized polyurethane foam or grout mixture is injected through the holes. This material expands and fills the voids beneath the slab.
- Lifting the Slab: As the material expands, it lifts the concrete slab back to its original level.
- Sealing: Finally, the drilled holes are sealed, and the surface is cleaned to complete the process.
Why Slab Jacking is a Better Solution
Slab jacking offers several advantages over other methods of leveling concrete slabs:
- Cost-Effective: It is significantly cheaper than replacing the entire concrete slab.
- Quick Process: The entire process can be completed in a few hours, minimizing downtime.
- Durability: The materials used in slab jacking are highly durable and long-lasting.
- Minimal Disruption: Since no heavy equipment is required, there is minimal disruption to the surrounding area.
- Eco-Friendly: The polyurethane foam used in the process is often made from recycled materials.
Additional Benefits of Slab Jacking
- Improved Aesthetics: Uneven concrete surfaces can significantly detract from the overall appearance of your property. Slab jacking restores the evenness and smoothness, enhancing the aesthetic value.
- Increased Property Value: Properly leveled concrete surfaces can potentially increase your property’s market value, as they reflect well-maintained infrastructure.
- Safety Enhancement: Trip hazards posed by sunken concrete slabs are eliminated, reducing the risk of injuries and potential liabilities.

FAQs
How does slab jacking work?
Slab jacking works by drilling small holes into the sunken concrete slab and injecting a grout mixture through these holes. The mixture fills the voids underneath, stabilizing the soil and lifting the slab back to its intended level.
What types of surfaces can be repaired with slab jacking?
Slab jacking is commonly used on driveways, sidewalks, patios, pool decks, and garage floors. It can also be used for some interior floors and foundation slabs.
Is slab jacking a permanent solution?
While slab jacking can provide a long-lasting solution, its effectiveness depends on the underlying cause of the sinking. If the soil conditions are stable and the mixture is applied correctly, slab jacking can last for many years.
Is slab jacking expensive?
Slab jacking is generally more cost-effective than completely replacing the concrete slab. Costs vary based on the size of the area being repaired and the extent of the damage, but it is usually significantly cheaper than full replacement.
How do I know if my concrete needs slab jacking?
Signs that your concrete may need slab jacking include noticeable sinking or uneven surfaces, cracks in the concrete, or water pooling in certain areas. A professional inspection can determine if slab jacking is the right solution.
