Cracked or deteriorating concrete doesn't automatically need complete replacement. The right solution depends on what caused the damage and the condition of the underlying slab.
Localized cracks, surface scaling, worn areas, and damaged edges may be candidates for professional repair or resurfacing when the remaining concrete is stable.
More serious warning signs include significant settlement, major movement, widespread deep deterioration, or sections that have become severely uneven. In these situations, simply repairing the visible surface may not address the underlying problem.
Tip: Don't decide based on appearance alone. Have the concrete assessed to determine whether repair, resurfacing, or replacement is appropriate. Addressing deterioration early may provide more repair options and help prevent the affected area from becoming worse.
