Application
Concrete steps and porch slabs
Precast or poured steps often settle away from the house, opening a gap at the threshold. Solid step units can sometimes be lifted and stabilized.
Why it settles
- Backfill settlement next to the foundation
- Water from eaves discharging at the steps
01 / Adjacent slab02 / Settled panel03 / Sub-base and soil04 / Void under panel
Often suitable
- Solid steps that have tilted or dropped as a unit
- Porch slabs with a gap at the house
Usually not suitable
- Steps with crumbling treads or exposed rebar
- Hollow steps with collapsed interiors — may need rebuilding
Risks, drainage and other considerations
- Handrail anchors may need adjusting after a lift
- Building code rise/run requirements still apply
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.

Questions
Can hollow precast steps be lifted?
Sometimes, depending on their construction and condition. An assessment should confirm.
