Can I coat or seal my garage floor instead of repairing it?

A sealer or epoxy coating applied over a failing slab will delaminate. Coatings are appropriate on structurally sound slabs as surface protection, not as a substitute for repair.

What is the typical thickness of a garage floor slab?

Residential garage slabs are typically 4 inches, sometimes 3.5 inches in older construction. If replacing, upgrading to 4-inch minimum is standard.

Garage floor: repair, resurface, or replace?

Replacement is necessary when the slab has settled significantly, large sections are cracked through, moisture is wicking up through the slab, or the base has failed. Resurfacing is appropriate only on structurally sound slabs. See our blog post: Garage Floor Concrete: Repair, Resurface, or Replace?

Exterior concrete around the home

Beyond the garage floor, homes often need work at the garage apron, exterior utility pads, side yard surfaces, and approach work adjacent to the structure. Read more: Exterior Concrete Around the Home: What Buyers Often Miss.
