Concrete Lifting Services in Christchurch
A sunken slab, tripping hazard, or an uneven join between your driveway and garage doesn't always mean you need a full replacement. Concrete lifting Christchurch homeowners choose raises sunken or settled concrete back to its original level by injecting a stabilising material beneath the slab, restoring a safe, even surface in a fraction of the time and cost of tearing everything out. At Christchurch Concrete Driveways, our concrete lifting services Christchurch wide are especially effective for driveways, footpaths, and patios affected by soil settlement, poor sub-base compaction, or drainage issues common in many Christchurch suburbs. Our Christchurch concrete lifting contractors assess the cause of the settlement first, since lifting a slab without addressing the underlying soil or drainage problem can mean the issue returns. We'll always give you an honest recommendation based on what will actually last.
Why Choose Our Christchurch Concrete Lifting Contractors
Concrete lifting is a specialised technique that requires the right equipment and an understanding of soil behaviour, particularly across Christchurch's variable ground conditions following the Canterbury earthquakes.
Our Christchurch concrete lifting contractors always investigate the cause of settlement, whether that's poor original compaction, drainage issues, or natural soil movement, so the fix addresses the real problem, not just the symptom.
Our Concrete Lifting Process
We drill small access holes into the sunken slab and inject a stabilising material beneath it, gradually raising the concrete back to its original level while monitoring the lift closely for an even result.
Once the slab is level, the access holes are patched and blended with the surrounding concrete, and the area is typically ready for light use again within a few hours.
Signs Your Concrete Needs Lifting
Common signs include a driveway that has visibly dipped, a noticeable step or lip where it meets the garage floor or footpath, or pooling water in one section after rain.
If the settlement is minor, concrete levelling or grinding may be enough, while significant structural damage may call for replacement instead — we'll advise the right option after a free inspection.
Christchurch Concrete Lifting Questions
Is concrete lifting cheaper than replacing a driveway?
In most cases, yes. Concrete lifting typically costs significantly less than demolition and a full repour, and the work can often be completed in a single day.
Will a lifted slab sink again?
Once we've identified and addressed the cause of the original settlement, a properly lifted slab is generally stable long-term. We'll also advise on any drainage improvements that can help prevent future movement.
How long does concrete lifting take?
Most residential concrete lifting jobs are completed within a single day, and the surface is typically ready for vehicle traffic again shortly after.
