Inspect the concrete
Prepare for Lifting
Lift & Stabilize
Finish the Repair
A contractor assesses the settled concrete and surrounding conditions to determine if lifting is a suitable repair option.
For injection based repairs, small access holes are drilled at carefully selected locations in the slab
Access holes are patched, and the repaired surface is inspected. The contractor explains when the concrete can be used again.
Specialized material is injected beneath the concrete to gradually raise settled sections and restore support.
Comparing Concrete Lifting Methods
Polyjacking vs Mudjacking: What's the Difference?
There are two common methods for raising settled concrete: polyurethane foam lifting (often called polyjacking) and traditional mudjacking. Both aim to raise sunken slabs without requiring fulll replacement.
Polyurethane foam lifting (polyjacking)
This method involves injecting expanding polyurethane foam beneath the concrete. the lightweight foam fills spaces below the slab and can help lift it back towards its intended position. It generally requires smaller injection holes and generally offers relatively quick curing times.
Traditional mudjacking
Mudjacking uses a cement based slurry pumped beneath the settled concrete to raise and support the slab. its an established repair method that can be cost effective, although the material is heavier and typically requires larger injection holes.
Which method is better?
Both methods have advantages. The most appropriate choice depends on the slabs condition, soil stability, drainage, project requirements and contractor assessment.
