Even a one-inch lip catches a toe. On a rental, a storefront, or a walkway visitors use, that’s a liability sitting in plain sight. We take it out fast, and the fix lasts.
Raised, sunken, or uneven sidewalk sections are one of Edmonton’s most common concrete problems, driven by hard freeze-thaw cycles, tree-root growth, and soil settlement over time. Whether it’s a single raised lip between two slabs or a whole section that’s dropped after years of spring thaw, there’s a fast, affordable fix that doesn’t involve tearing anything up.
Sidewalk leveling with polyurethane foam raises settled sections back to level in under two hours per section, with no excavation, no landscaping damage, and no week of waiting for new concrete to set. You can walk on it right away. We lift sunken front steps and porch landings the same way. If the driveway is sinking too, we level both in one visit for one trip charge.
| Option | Relative cost | Time | Outcome |
|---|---|---|---|
| Poly Lift foam leveling | Lowest for a lasting fix | 1–2 hours | Level, stabilized, permanent |
| Full replacement | $4,000–$8,000+ | 2–3 days | New slab on the same soil |
| Mudjacking | Low, but may need redoing | 2–3 hours | May resettle as slurry erodes |
| Grinding / shaving | Cheap, but temporary | Under 1 hour | Cosmetic only, hazard returns |
Inspect & measure — We assess each section, measure the displacement, and find the cause of the settlement.
Drill small holes — 5/8" holes at strategic points, small enough to be nearly invisible once patched.
Inject foam — High-density polyurethane expands under the slab, fills the voids, and lifts it precisely to level.
Patch & clean — We patch the holes to match the concrete and leave the area clean and ready to use.
Grinding or edge-shaving is sometimes sold as a quick fix for a raised lip. It can shave down the trip edge for now, but it treats the surface while the real problem, unstable soil and ongoing settlement, keeps going underneath.
Replacing a sunken sidewalk or walkway typically runs $4,000 to $8,000 or more, so lifting it back into place costs a fraction of that — most homeowners save 50 to 70 percent versus replacement. Grinding can look cheaper upfront, but it only shaves the lip while the settling continues. Every quote is a fixed price after a free assessment.
There’s no hard limit. We control the lift by adjusting injection pressure and volume. Most sidewalk sections only need 1 to 2 inches to clear the trip hazard, but we’ve moved slabs much more when the situation called for it, with precise control the whole way up.
We patch the 5/8" holes. They show right after the repair, then blend in over time, and they’re far less noticeable than the large holes mudjacking needs or the fresh seams of a full replacement.
Often, yes. As long as the concrete isn’t badly cracked or broken, we can lift it even where roots have pushed it up. If the roots keep growing, the problem can return, so we’ll look at your specific situation and tell you what to expect.
In Edmonton the City usually maintains public sidewalks in the road right-of-way, but you’re generally responsible for walkways and paths on your own property. If you’re not sure which is which, we can help sort it out during the free assessment.
Up front, sometimes. But grinding only shaves the lip while the slab keeps settling, so the hazard comes back and the edge is left thin and weak. Foam lifts the whole section back to level and fills the void underneath, so it’s a one-time fix rather than something you redo.
