Concrete Slab Jacking A Smart Alternative to Concrete Replacement
                     Concrete Slab Jacking - A 
Smart Alternative to 
Concrete Replacement
Restoring stability and safety to sunken concrete without the cost 
and disruption of full replacement
THE PROBLEM
Why Do Concrete Slabs Sink?
Solid compromise rarely happens overnight. 
It develops gradually as the soil beneath the 
slab loses its ability to bear weight, creating 
voids that cause the concrete to sag, tilt, and 
crack.
Several factors contribute to this progressive 
settlement, from natural soil changes to 
construction issues. Understanding these 
causes helps property owners recognise 
problems early and take corrective action.
Common Causes of Concrete Settlement
Soil Erosion Expansive Clay Poor Compaction
Water runoff and drainage Clay soil shrinks and swells with Inadequate soil preparation 
problems wash away supporting moisture changes, destabilising during construction creates weak 
soil beneath the slab the foundation support from the start
Leaking Pipelines Natural Settlement
Underground pipe leaks erode soil and create voids Over time, soil naturally compacts and shifts, 
directly beneath concrete surfaces gradually reducing its load-bearing capacity
The Slab Jacking Process
Controlled Injection Process
Detailed Site Assessment
Small access holes are drilled in the slab, allowing lifting

Is Slab Jacking Right for Your Property?
Ideal Conditions for Slab Jacking
Concrete slab jacking is ideal when the slab remains structurally 
sound but has become uneven due to settlement. If cracking is 
minimal and the primary issue is displacement rather than 
deterioration, slab jacking is often the most efficient and cost-
effective repair option available.
Warning Signs to Watch For
• Uneven concrete surfaces creating trip hazards
• Standing water pooling on slabs
• Visible gaps between slab and adjacent structures
• Doors or garage mechanisms that no longer function properly
