Why do concrete slabs suffer subsidence (sinking) and become unlevel?

The earth below the concrete slab can suffer settlement, can be washed away by excessive water or be compressed by the weight of the concrete its self.

Sinking concrete can also be a symptom of a mixture of the above causes.

This website will provide detailed explanations as well as summarised information chunks to help you learn everything you need to know about concrete slab lifting (Slab Jacking).

Save money by lifting your concrete slab or house footing with polyurethane foam.

Concrete Slab Jacking Minimises Your Liability

Trip Hazards.

Lifting a concrete slab with high pressure urethane injection costs a fraction of removing a slab and replacing it. Our high-flow resins dry so quickly that after your concrete has been lifted, you can drive a vehicle the repaired concrete slab within 15 minutes. Quick setting times means that we can even fill voids below a slab  in emergency situations during rain (with active running water) to stop active erosion of the earth below your concrete slab instantly. Eliminate trip hazards fast and stop   your exposure to liability.

Here's What Concrete Slab Lifting Can Help Solve

Sinking Concrete Floors

Did you know that if the soil beneath your home moves, it can cause your floor to sink? This can cause problems throughout the entire house or just in a few isolated spots.

Walls With Cracks

When the foundation is damaged or there are structural problems, it can lead to cracks appearing on walls and in concrete surfaces.

Structures Shifting

Having trouble opening and closing doors or windows? It could be because your floor is uneven due to subsidence.

Eroding Soil Below Slabs

Constant flooding can wreak havoc on your home by forming a void that weakens the foundation, leading to serious damage.

Releveling Concrete Floors

Levelling concrete floors with injection involves repairing uneven flooring by injecting grout or polymer into cracks or voids. This creates a level base and helps prevent future damage. It's a cost-effective, minimally disruptive solution for fixing concrete flooring.

Water Tunneling

Water can wash away soil from below a concrete slab by penetrating into the soil and eroding it. This can cause the soil to shift, leaving voids beneath the slab. Over time, the weight of the slab can cause it to sink or settle into these voids, leading to an uneven surface and potential cracking or damage to the slab.

The Benefits of Concrete Slab Lifting

Concrete slab lifting is a cost-effective and efficient method for repairing uneven or sinking concrete slabs. 

This method involves injecting a specialized foam or grout under the slab to lift it back to its original position. This process is quick and minimizes disruption to the surrounding area, as well as providing a permanent solution to the problem. 

Using concrete slab lifting can help to prevent further damage to the slab and the surrounding structures, as well as restore the functionality and appearance of the surface. Additionally, it can help prevent trip hazards, improve accessibility, and enhance the overall value of the property.

Are you dealing with sunken, uneven concrete slabs on your property? You’re not alone. This is a common problem that affects many homeowners and business owners. But don’t worry, there is a solution: concrete slab lifting, also known as slab jacking.

What is Concrete Slab Lifting?

Concrete slab lifting is a process that involves injecting a special material underneath sunken or uneven concrete slabs to lift them back into place. This material, usually a polyurethane foam that becomes solid, is pumped through small holes drilled in the slab. Once the material is in place, it hardens and stabilizes the slab, restoring it to its original position.

Why is Concrete Slab Lifting Important?

Concrete slab lifting is important for several reasons. First, it can save you money. Instead of tearing out and replacing the entire slab, which can be costly and time-consuming, you can simply lift and stabilize the existing slab. This can result in significant cost savings.

Second, concrete slab lifting is less disruptive to your property than traditional methods of repair. Because there is no need to remove and replace the slab, there is less noise, dust, and debris. This means less disruption to your daily routine and less inconvenience for your family or customers.

Third, concrete slab lifting provides a long-lasting solution to the problem of sunken or uneven concrete slabs. By stabilizing the slab, it can prevent future damage and extend the life of your concrete.

How Does Concrete Slab Lifting Work?

The process of concrete slab lifting is relatively simple. First, small holes are drilled in the sunken or uneven slab. Then, the special material is injected through the holes and into the void underneath the slab. As the material expands, it lifts the slab back into its original position.

The material used for concrete slab lifting is strong and durable, and it can withstand heavy loads and extreme weather conditions. Once the material has hardened, it stabilizes the slab and prevents future sinking or settling.

Common Concerns About Concrete Slab Lifting

One common concern people have about concrete slab lifting is whether it is environmentally friendly. The good news is that the materials used for concrete slab lifting are non-toxic and environmentally safe. In fact, concrete slab lifting is often considered a “green” solution because it reduces waste and minimizes the need for new materials.

Another concern people may have is whether concrete slab lifting will damage their property. Again, the answer is no. The small holes drilled in the slab are typically less than 2 inches in diameter, and they can be easily filled with a colour-matched material after the lifting process is complete.

Real-Life Examples of Concrete Slab Lifting

Concrete slab lifting has been used successfully in many different applications, from residential driveways and sidewalks to commercial parking lots and warehouse floors. Here are some real-life examples of successful concrete slab lifting projects:

  • A homeowner in Sydney had a sinking front porch that was causing water to pool near the foundation. Concrete slab lifting was used to lift the porch back into place and prevent further damage.

  • A business owner in Bondi had a sunken loading dock that was causing safety concerns. Concrete slab lifting was used to lift the dock and provide a level surface for loading and unloading.

  • A school in Mosman had a sinking walkway that was causing trip hazards for students and staff. Concrete slab lifting was used to lift the walkway and eliminate the safety hazard.


If you’re dealing with sunken or uneven concrete slabs on your property, concrete slab lifting may be the solution you need. It’s a cost-effective, less disruptive, and long-lasting solution that can restore
