Commercial Concrete Grinding & Leveling
Grinding, leveling, polishing, and floor prep for warehouses, retail spaces, and offices in the Phoenix Valley and throughout Arizona — licensed, bonded, and built around your business hours.
Commercial Concrete Grinding in Phoenix
Your concrete floor doesn’t fail all at once. It wears down where the abuse is heaviest — a forklift lane that’s developed grooves, a dock corner chipped from years of pallet jacks, old thinset hiding under the dust from a flooring job nobody remembers doing.
Flatline Concrete Grinding has worked on this kind of wear for more than 20 years, across warehouses, retail spaces, offices, and industrial buildings throughout Phoenix. Every floor is different, so we start by finding out what’s actually wrong before deciding how to fix it.
A sunken slab near your loading dock needs leveling. A retail space going in for new vinyl plank needs the old mastic ground off and the surface flattened. A lobby you’re trying to give a polished look needs a different process than a parking lot that just needs a trip hazard gone. We walk the floor first, then match the process to the problem — not the other way around.

Grinding, Leveling & Surface Prep
Uneven concrete inside a warehouse or retail space isn’t just cosmetic — it’s a liability the moment a forklift, a pallet jack, or a customer catches an edge. We grind down high spots, level out low areas, and take uneven slabs back to flat before they become a safety issue or a line item in a lawsuit. High spot and crack repair is one of the most requested parts of this work, since those are usually the spots that trip inspections or trip people. Whether you’re prepping for new flooring, dealing with a slab that’s settled unevenly, or just need the surface leveled before equipment goes in, we handle it on-site without tearing out the existing concrete.
Polishing & Grind and Seal
Once your floor is ground flat, you’ve got two ways to finish it. Polished concrete runs through progressively finer grits until the surface takes on a glossy sheen — a popular choice if you’re running a showroom, retail floor, or office. Grind and seal is the more budget-friendly option: we grind the surface flat, then apply a protective sealer and skip the extended polishing passes. Either way, you end up with a floor that holds up to daily traffic far better than bare concrete.
Commercial Trip Hazard Repair
& ADA Compliance
A raised slab edge at your entrance, a lifted joint in the parking lot, or an uneven transition at the loading dock doesn’t look like much until someone catches a foot on it — then it’s an incident report with your business name on it. The ADA treats anything over a quarter inch of vertical change as a hazard, and insurers take notice when a claim traces back to a defect that was visible beforehand. Our commercial trip hazard repair grinds these edges flush with the surface, closing the gap without the cost of replacing the slab, and we can schedule the work after hours if you can’t afford to shut down during the day.
Coating, Epoxy & Adhesive Removal
If your old epoxy is peeling, bubbling, or gone yellow, nothing new is going to bond to it — a coating applied over a failing one just fails faster. The same goes for thinset left behind from an old tile job. All of it has to come off down to bare concrete first.
We strip coatings and adhesive residue back to clean concrete — standard prep work whether you’re resurfacing, installing a new epoxy system, or swapping out flooring entirely. Skip this step and whatever goes down next won’t hold.

Frequently Asked Questions

Take a look at the FAQs and reach out anytime if you’ve got questions left unanswered.
-
Cost scales with square footage, floor condition, and the finish required — a warehouse floor grind is priced differently than trip hazard repair at an entryway. Flatline Concrete Grinding quotes commercial concrete grinding services in Phoenix on site rather than by square-foot estimate alone.
-
-
Concrete floor prep phoenix businesses need before a flooring install means grinding down old adhesive, thinset, and uneven high spots so vinyl, tile, epoxy, or wood flooring goes down on a flat slab — this is one of the most common jobs ahead of a retail buildout or office renovation.
-
Yes — Flatline grinds away old epoxy coatings along with thinset, mastic, and paint residue, clearing the slab for a new coating, polish, or flooring system. This is standard prep work before resurfacing a commercial floor anywhere in the Phoenix area.
-
Commercial trip hazard repair grinds down a raised slab edge or joint at an entryway, loading dock, or parking area until it’s level with the surrounding surface, which reduces the kind of elevation change that creates ADA compliance issues and liability exposure.
-
Grinding levels and smooths a rough or damaged surface; polishing takes that ground surface further into a glossy, finished floor; grind and seal adds a sealant on top for a durable, low-maintenance finish without the full polish process. Flatline offers all three for commercial properties across the Phoenix area and is licensed and bonded under ROC214703.
