Concrete leveling is often misunderstood. Here are seven myths Spokane homeowners hear most often — and the practical reality behind each one.

Concrete leveling is a specialty trade, and specialty trades collect myths. Here are seven that come up regularly with Spokane homeowners — and what's actually true.


Myth 1: You have to replace uneven concrete

Reality: many structurally sound slabs are candidates for concrete leveling. Full replacement is usually reserved for concrete that's already crumbling — see concrete leveling vs. concrete replacement.

Myth 2: Foam leveling is a temporary fix

Reality: polyurethane foam is inert, waterproof, and used as structural fill under highways and airport runways. Its longevity is covered in how long does concrete lifting last?.

Myth 3: Mudjacking is the same thing

Reality: mudjacking uses a cement-based slurry through larger ports; polyurethane foam is lighter, uses smaller ports, and cures much faster — full comparison in polyurethane foam vs. mudjacking.

Myth 4: Cracks mean the slab can't be lifted

Reality: hairline cracks along control joints are common and usually don't disqualify a slab. See can cracked concrete be leveled?.

Myth 5: Leveling ruins the appearance

Reality: injection ports are dime-sized and are sealed with color-matched patches. The slab surface looks essentially the same, just level.

Myth 6: Winter in Spokane rules it out

Reality: foam itself is unaffected by cold. Snow cover and access are the real constraints — most work is scheduled in the shoulder seasons for convenience, not chemistry.

Myth 7: All slabs are candidates

Reality: they're not. Severely deteriorated concrete usually needs replacement, and only an on-site evaluation can tell for certain. Request a free estimate to find out.
