Application
Commercial and industrial slab leveling
Commercial slabs settle for the same reasons residential ones do, but loads, tolerances and liability are higher. Polyurethane lifting can be part of a solution for intact slabs; larger projects often warrant engineering input.
Why it settles
- Sub-base consolidation under heavy loads
- Joint deterioration allowing water entry
- Washout from roof drainage
Often suitable
- Settled slab panels at joints
- Walkways and aprons with trip edges
- Voids beneath slabs
Usually not suitable
- Structural slabs or suspended floors
- Slabs requiring specific flatness tolerances without engineering review
Risks, drainage and other considerations
- Engineering review is advisable for structural or high-load areas
- Operations scheduling and access planning
- Load-bearing capacity of foam products should be matched to use
Lift or replace?
Lifting keeps the existing concrete, so it makes sense only when that concrete is worth keeping. If it is broken up, deteriorated or heaved, replacement is usually the better route. See lifting vs replacement and what affects cost.
Check before you ask

Questions
Do you need an engineer?
For structural elements or high-load floors, involving a structural engineer is prudent. For simple walkway lifts it may not be necessary.
