Concrete Floor Repair & Coating — Dallas, TX
Crack repair, divot fill, and full resurface before coating — restoring degraded Dallas slabs in one mobilization without replacement.
Concrete cracks, spalls, and degrades — especially on Dallas slabs built over the Blackland Prairie clay that expands and contracts with every wet-dry cycle North Texas delivers. Replacing a garage or basement slab costs a significant amount and disrupts the entire structure above it. In most cases, it isn’t necessary. Our concrete repair-and-coat service restores cracked, spalled, and stained slabs to a smooth, coated surface in a single mobilization: we grind, fill, resurface where needed, then apply the full epoxy and polyaspartic coating system over the repaired slab. The result is a floor that looks and performs like new — without the demolition and replacement cost. Call (469) 564-4886 for a free on-site assessment anywhere in Dallas, Plano (75023), Irving (75061), Garland (75040), or the greater DFW area.
Why Dallas Concrete Needs Repair Before Coating
The Blackland Prairie clay under most of Dallas and its northern suburbs is the root cause of most concrete floor problems in the DFW area. This clay is classified as “highly expansive” — it absorbs water and swells, then dries and shrinks. The seasonal movement creates upward pressure on slabs from below, causing hairline cracks that widen over years, settlement at slab edges where the clay shrinks away, and surface spalling where repeated thermal cycling has degraded the top layer of concrete.
The worst-hit areas in our experience are older neighborhoods in Garland (75040), Mesquite (75149), and parts of Irving (75061) where slabs were poured in the 1950s–70s, before modern mix designs and before vapor barriers under slabs were standard. Many of these slabs are still structurally sound but have surface conditions that require prep work before any coating can achieve proper adhesion.
Coating over unrepaired cracks and spalling isn’t just aesthetically problematic — cracks telegraph through the coating, and loose spalled concrete creates adhesion voids that grow into delaminated patches under traffic. We repair first, coat second, every time.
Types of Concrete Damage We Repair
Hairline Cracks
Surface cracks under 1/8″ wide are typically non-structural shrinkage or settlement cracks. We rout them to a consistent width, vacuum clean, and fill with semi-rigid polyurea filler that cures to the same hardness as the surrounding concrete. Hairline cracks filled with the right filler don’t telegraph through the coating.
Structural & Active Cracks
Cracks wider than 1/8″ or showing vertical displacement (one side higher than the other) indicate slab movement. We fill these with flexible-cure polyurea that accommodates minor ongoing movement without re-cracking through the coating. We document and disclose any crack that suggests underlying structural movement requiring a foundation evaluation.
Surface Spalling
Spalling — where the surface layer of concrete flakes or pops off — is common on 40–60 year old Dallas slabs and on any slab that has absorbed road salt from ice treatment on nearby driveways or parking areas. Diamond grinding removes the loose spalled layer to reveal sound concrete below, and a skim coat of epoxy mortar resurfaces the area before the base coat.
Pitting & Divots
Aggregate pop-out, divots from dropped tools, and pitting from chemical attack are filled with epoxy mortar or polyurea filler and leveled flush with a grinder before the base coat. On heavily pitted slabs, a self-leveling epoxy skim coat brings the entire surface to a uniform profile.

Repair & Coat Process
Damage Assessment & Written Scope
We photograph and document every crack, spall, and stained area. The written quote separates repair scope from coating scope — you see exactly what each element costs and why it’s necessary.
Diamond Grinding
Entire slab ground to CSP-2 profile. Grinding simultaneously removes surface spalling, old paint, sealers, and contaminants, and opens the concrete pores for adhesion. On severely spalled slabs, multiple passes are needed to reach a sound surface layer.
Crack Routing & Filling
Cracks are routed to a consistent 1/4″ V-groove width with a crack chaser. Routing prevents the crack edges from telegraphing through the filler under thermal cycling. Filled with semi-rigid or flexible polyurea as appropriate. Allowed to cure fully before the next step.
Spalling & Divot Repair
Spalled areas filled with epoxy mortar and leveled flush with a surface grinder. Heavily damaged areas get a self-leveling epoxy skim coat over the entire affected zone for a uniform base.
Primer + Base Coat + Flake
Vapor-block primer, 100% solids epoxy base coat, and full vinyl flake broadcast applied per the standard system. The repaired slab accepts the base coat the same way a pristine slab does — that’s the point of thorough prep.
Polyaspartic Topcoat
UV-stable polyaspartic clear coat locks in the flake and delivers the final surface. Written warranty certificate issued at walkthrough.
Concrete Repair FAQ — Dallas, TX
Do I need to replace my cracked slab, or can it be repaired and coated?
Most cracked Dallas slabs can be repaired and coated without replacement. Replacement is warranted when the slab has major structural displacement (one section significantly higher or lower than adjacent sections), when there is evidence of void formation beneath the slab, or when the concrete itself has carbonated or degraded throughout its full depth. In our experience, fewer than 10% of cracked slabs we assess actually require replacement — the rest are repairable and coatable.
Will repaired cracks show through the epoxy?
Properly routed and filled cracks don’t telegraph through a correctly applied full-broadcast flake system. The flake layer and topcoat together create enough visual complexity that a filled crack is invisible. Smooth metallic finishes are more likely to show a filled crack line, which is why we recommend flake systems for heavily cracked slabs.
What causes concrete spalling on Dallas garage floors?
Three main causes in DFW: (1) freeze-thaw cycling on slabs exposed to ice-melt chemicals, which drives salt crystals into the surface and pops aggregate off; (2) rebar corrosion beneath the surface, which expands and breaks the concrete above it — common on 50+ year old slabs; (3) concrete that was over-finished when poured, pulling too much water to the surface and creating a weak top layer. We identify the cause at inspection and document it in the written scope.
Can you repair a floor that has oil contamination?
Yes. Oil that has penetrated the concrete surface is addressed by diamond grinding to remove the contaminated layer, followed by an oil-block primer over any areas that still show staining after grinding. The primer creates a barrier that prevents oil from bleeding through the epoxy base coat. This is a standard step on any slab with long-term vehicle parking history in Mesquite (75149), Garland (75040), and older neighborhoods in Dallas proper.
Do you serve Richardson, Frisco, and Carrollton?
Yes — we repair and coat concrete floors throughout DFW: Richardson (75080), Frisco (75033), Carrollton (75006), Plano (75023), Irving (75061), Garland (75040), Mesquite (75149), Grand Prairie (75050), and all of Dallas proper.
