Concrete Slab Jacking Repairs and Slab Lifting in Sydney, Australia

Slab jacking is a specialised concrete repair technique designed to lift sunken concrete slabs. This process involves pumping a material beneath the slab, which raises it from below.

Also known as “mudjacking” or “pressure grouting,” this method is an effective solution for restoring the level and stability of concrete surfaces.

There are many different causes of subsidence and various contributing factors. All involve some sort of change in the ground, which, in turn, generates movement of the soil.

Tree roots can gradually bulge beneath your concrete, eventually pushing it upward. This can lead to cracks, uneven slabs, and other structural issues.

Another common cause of rising concrete is poor soil conditions. For instance, soils like clay tend to absorb more water than other types of fill material, causing the ground to shift and disrupt the concrete above.

Slab jacking, also known as mud jacking or concrete levelling, is a cost-effective method for raising and strengthening sunken concrete slabs.

In Australia, the cost of slabjacking varies based on factors such as the size of the area, the extent of subsidence, and accessibility.

It’s important to note that slab jacking and slab lifting  in Sydney is typically more affordable than replacing the entire concrete slab, often costing about one-third of the replacement price.
