Patios
A backyard patio that has sunk or tipped toward the house holds water against the foundation. We lift it so it slopes away again.
Concrete lifting / Slab lifting
Garage floor, patio and step lifting in Edmonton
Garage floors that dropped at the door, patios that sank toward the house and front steps pulling away from the wall can often be lifted in place with polyurethane foam.
What we fix
Slabs around the house that dropped
Garage floors, patios, pool decks and front steps all sink for the same reason: the ground under them moved.
Garage, patio and step lifting raises sunken concrete back to level by injecting polyurethane foam under the slab through small drilled holes. Aires lifts garage floors, patios, pool decks and front stoops for homeowners in Edmonton and nearby towns.
The foam expands into the void, fills it and pushes the slab up. Once cured it's strong, water resistant and permanent, so it won't wash out the way loose soil does. It costs less than breaking out the slab and pouring new concrete, and you skip the wait while new concrete cures. For the full method, see concrete lifting.
Garage floors
Why garage floors sink at the door
Many garage floors are floating slabs. They're poured inside the foundation walls but not tied to them, so the slab moves on its own as the soil under it settles. The walls stay where they are. The floor drops.
The usual trouble spot is the front of the garage, at the apron by the overhead door. That concrete sits on backfill next to the foundation, it gets the snowmelt off your truck all winter, and it often has a crack running across it where the slab has started to tip.
Floating slabs need care. We look for floor drains, any lines under the slab and where the floor meets the walls before we drill, and we lift in small steps so the floor doesn't bind against the foundation.
- A gap or step where the garage floor meets the driveway
- A crack running across the floor near the overhead door
- Water pooling in the low corner instead of draining out
- The overhead door seal no longer touching the floor
Other slabs
Patios, pool decks and steps
Smaller slabs, but the same problem and the same fix.
Pool decks
Uneven deck panels around a pool are a trip hazard on wet concrete. We check where the pool plumbing runs before drilling.
Front steps and stoops
A concrete stoop that dropped or pulled away from the house leaves a gap at the wall and a taller step at the door.
The process
How we lift a garage floor or patio
We lift a little at a time and keep a level on the slab the whole way.
Assessment
We measure how far the slab dropped, look for drains and buried lines, and check that the concrete is sound enough to lift.
Drilling
Small holes go through the slab at the low spots.
Injection
Polyurethane foam goes under the slab, fills the void and raises it. On a floating garage floor we go slowly near the walls.
Stabilization
The foam cures underneath. We patch the holes, check the level and clean up.
Lift or replace
Not every slab can be saved
Lifting brings a slab back to level. It doesn't repair the concrete. A garage floor broken into many pieces, a patio with a crumbling surface or a stoop that has split through needs to be replaced. We'll tell you at the assessment if that's where your slab is.
After a lift, deal with the water that caused the drop. Move or extend downspouts that drain near the slab, and seal the joint between the garage apron and the driveway so meltwater doesn't run underneath.
Driveways, walks and booking
If the problem is out front on the driveway or the walk, see driveway and sidewalk lifting. Many homes have both: a dropped garage apron and a driveway panel next to it, and we can quote them together.

FAQ
Questions we get asked
Can a sunken garage floor be lifted?
Often, yes. Garage floors usually sink at the overhead door, where the slab sits on backfill. If the concrete is solid, we inject polyurethane foam under the low area to lift it back to level. Badly broken floors need replacing.
What is a floating garage slab?
It is a garage floor poured inside the foundation walls without being tied to them, so it can move on its own as the soil under it settles. Many garages are built this way, which is why the floor can drop while the walls stay put.
Can you lift a patio that slopes toward the house?
Yes, if the patio is solid concrete. A patio tipped back toward the house sends rain at the foundation. We lift the low side so the slab drains away from the wall.
Do you lift front steps and stoops?
Yes. A concrete stoop that has dropped or pulled away from the house leaves a gap and a bigger step at the door. We assess it on site and lift it if the concrete is sound.
Do you lift basement floors?
Call us and describe the floor. This page covers garages, patios, pool decks and steps. We'll tell you on the phone whether an interior basement slab is something we can take on.
