Concrete Floor Repair in Reno, Nevada

A Reno garage slab takes a beating. Summer heat, freeze-thaw cycles, deicer salt tracked in from snowy nights at Mt. Rose, and twenty or thirty years of vehicles pulling in and out add up. Cracks open. Spalls form near the door. Joint edges chip. Pits show up where something heavy was dropped. We repair concrete floors in Reno as a standalone service for homeowners who just want their slab back in working shape, and as a prep step before our coating systems for homeowners going on to a full epoxy or polyaspartic finish.

What We Repair

Surface cracks and hairline cracks in residential and light-commercial garage slabs
Wider working cracks that move with seasonal slab expansion and contraction
Joint edge damage where control joints have chipped open under vehicle traffic
Surface spalling where the top layer of concrete is flaking off, common near garage doors in Reno
Pitting from dropped tools, jacks, or impact damage
Heavy abrasion areas where tires or skids have worn the surface concrete down
Old failed patches that need to be cut out and re-done correctly
Full slab resurfacing with a polymer-modified overlay where the slab is cosmetically rough but structurally sound

Why Reno Garage Slabs Crack And Spall

Reno's combination of cold winter nights, sharp daily temperature swings, and dry summer heat is hard on concrete. Three failure modes are most common in Reno garages:

Freeze-thaw spalling. Water gets into the top of the slab through small pores. It freezes overnight and expands. Repeated cycles pop small flakes (spalls) off the surface, usually starting at the garage door apron where snowmelt sits and at any low spot that holds water.

Deicer attack. Magnesium chloride and similar deicers tracked in on tires from city roads and from Mt. Rose Highway accelerate freeze-thaw damage and dissolve cement paste at the surface.

Shrinkage and settlement cracking. Newer slabs that were poured a little too wet or cured a little too fast develop hairline cracks as they shrink. Slabs over fill that settled show wider cracks. Most of these can be repaired before they get worse.

Our Repair Process

Walk and assess. We look at every crack, spall, pit, and joint to identify what needs to be done. Working cracks are flagged. Structural concerns are flagged.
Chase and clean. Cracks are chased open with a crack saw or grinder to expose sound concrete on both sides. Loose material is vacuumed out.
Patch. A polymer-modified, fast-curing crack filler or patch mortar is troweled into the prepared crack or void. The patch is feathered into the surrounding concrete.
Grind smooth. Once the patch is set, the area is ground smooth so it does not telegraph through any future coating.
Joint treatment. Control joints are either honored (preserved as a visible line in the new floor) or filled with a flexible semi-rigid filler depending on slab movement.
Optional resurface or seal. Some slabs get a polymer-modified overlay to give a clean working surface. Some just get a penetrating sealer to slow future damage. Some go straight on to a full coating.

Repair Standalone Or With A Coating

We quote concrete repair two ways, depending on what the Reno homeowner actually wants:

Standalone repair. Cracks and spalls fixed, slab ground smooth, optional penetrating sealer applied. The slab is back to working shape. No decorative finish.

Repair plus coating. All the repair work above, then a full epoxy or polyaspartic system installed over the top. The coating hides the repair work entirely and gives a finished floor. Most Reno homeowners with significant slab damage go this route because the cost difference is smaller than they expect once the diamond grinder is already on site.

Concrete Floor Repair FAQs

Can every concrete crack be fixed before a coating?

Most surface cracks and hairline cracks can be repaired in a way that is invisible under a finished coating. Wider working cracks (over 1/8 inch) and slab movement at control joints require a different detail: an isolation joint or a flexible filler that lets the slab continue to move without telegraphing back through the new floor. We identify which detail your slab needs during the in-garage walk.
