Concrete Crack Repair & Surface Prep Done Right
Cracked, pitted, or uneven concrete repaired and leveled before any coating goes down, the foundation work that determines whether your floor actually lasts.

Why Prep Work Is the Part Nobody Sees
This is the step contractors skip when they’re racing to finish a job cheap, and it’s the reason so many epoxy floors fail early. Cracks left unrepaired telegraph through the new coating. Low spots collect water underneath. And a slab that isn’t properly ground won’t let the epoxy bond correctly, no matter how good the topcoat is. We diamond-grind every surface to open the concrete pores, fill and level cracks with a flexible polyurea filler that moves with the slab, and moisture-test before any coating goes down. If your existing floor is failing because of bad prep work the first time around, we can also strip and re-prep it.

Who Needs Crack Repair & Prep
This service isn’t just for people getting a new coating. Here’s who calls us for prep work alone:
- Home sellers whose inspector flagged foundation or slab cracks
- Homeowners whose old epoxy or paint coating is peeling because it was applied over bad prep
- Anyone with a garage, patio, or basement slab that collects water in low spots
- Businesses with damaged industrial or warehouse floors before a re-coat
- Homeowners who just want cracks and unevenness fixed, with no coating at all
Crack Repair Questions We Hear a Lot
How do I know if my cracks are just cosmetic or a real problem?
That’s exactly why we do a free assessment before quoting anything. Hairline surface cracks are usually cosmetic, while wider cracks, cracks that run through the slab, or ones with vertical offset can point to settling. We’ll tell you honestly which one you’re dealing with.
Can you just fix the cracks without doing a full epoxy coating?
Yes. Plenty of customers just want the slab repaired and leveled with no coating on top. If you decide you want the extra protection later, our garage floor coating and other services are always available.
How long does moisture testing take, and why does it matter?
It’s built into the same visit, no extra trip required. It matters because moisture trapped under a slab is one of the most common reasons epoxy coatings fail in Charleston’s humid climate. Testing before we coat means we catch the problem instead of covering it up.
