Slab Jacking
Slab jacking, also known as concrete lifting or mudjacking, is a proven method for raising and leveling sunken or uneven concrete surfaces. Over time, concrete slabs like driveways, sidewalks, patios, or garage floors can settle due to soil erosion, moisture changes, or poor compaction beneath the slab.
During the slab jacking process, a specialised grout mixture is pumped through small holes drilled into the affected concrete. This mixture fills the voids beneath the slab, lifting it back to its original level while providing a stable foundation. Slab jacking is cost-effective, minimally invasive, and typically faster than full concrete replacement. It restores safety, improves appearance, and prolongs the life of your concrete surfaces.
Slab Jacking (Concrete Raising)
The slab jacking process begins by drilling small, strategically placed holes into the affected concrete slab. Through these holes, a specially formulated slurry—a mixture of cement, water, and sometimes polymers—is injected under high pressure. This slurry fills the voids beneath the slab, compacting loose soil and lifting the concrete back to its original level. In some modern techniques, polyurethane foam is used instead of traditional grout. Polyurethane expands as it cures, creating a lightweight, strong, and water-resistant foundation that stabilizes the slab permanently.
Unlike full concrete replacement, slab jacking is minimally invasive, cost-effective, and environmentally friendly. The process is fast, often completed in a single day, and allows immediate use of the repaired surface. Beyond restoring level surfaces, slab jacking strengthens the underlying soil, prevents further settling, and prolongs the life of your concrete, making it a smart choice for driveways, sidewalks, patios, pool decks, and commercial flooring.
