Why Level Your Concrete Floor?

Uneven concrete causes tripping hazards, cracks epoxy coatings, and ruins tile installs. Common in Toronto homes due to frost heave and settling.

  • •Prevents Coating Failures: Epoxy and polyaspartic need flat surfaces.
  • •Safety First: Eliminates dips and lips in high-traffic areas.
  • •Improves Aesthetics: Smooth base for garage epoxy.
