Honest repair guidance
When Concrete Lifting Will Not Work
Concrete lifting is a strong option when the slab is mostly intact and unsupported. It is not always the right answer when the concrete, drainage, or structure needs a different fix first.
Quick answer
Concrete lifting works best when a slab is mostly intact but has settled because of voids, soil movement, erosion, or poor support. It may not be the right repair when the concrete itself is too broken, the movement is structural, or drainage and washout problems must be corrected first.
- The slab is severely cracked into many loose pieces.
- The surface is badly spalled, crumbling, or structurally weak.
- Tree roots have pushed the concrete upward.
- Water is actively washing soil out from under the slab.
- Drainage needs to be corrected before the slab is stabilized.
- The issue is tied to structural foundation movement.
- The concrete needs replacement for appearance, thickness, or load reasons.
- The slab carries a load that requires closer structural review.
What the inspection is looking for
A short site visit usually gives enough evidence to separate a good polyjacking candidate from a slab that needs replacement or another repair first.
Slab condition
Mostly intact concrete with settlement is a better fit than concrete that is shattered, crumbling, or too thin to stabilize well.
Soil support
Voids and weak support can often be filled. Active washout or drainage problems may need correction before lifting.
Repair goal
The goal is a safer, more usable slab. If appearance or structural performance requires new concrete, replacement may be the better call.
