Chicagoland's Trusted & Fastest Epoxy & Flooring Contractor
Garage floors, basements, and shop floors that you hose off instead of scrub. We diamond grind the slab first so the coating actually bonds, then finish it in flake, metallic, or solid color. Every floor you're about to see was done by our crew, in days.

Why Choose Us
★ ★ ★ ★ ★
Most epoxy floors that fail didn't fail because of the coating. They failed because whoever laid it skipped the prep — acid-etched or power-washed instead of grinding, and the epoxy never bonded to anything. It looks perfect for a year, then the hot tires lift it in strips.
We grind every floor. It's slower and it costs more, and it's the difference between a floor that lasts and a floor you pay for twice.
Here at Expansive Epoxy, we strive to provide the best experience for our customers. We respond quickly, complete our service in an orderly fashion, and you will love our work!

Common Questions
Are you grinding the concrete, or just cleaning it?
Ask every company this. Epoxy doesn't bond to smooth concrete — it bonds to concrete that's been opened up. If someone is acid-etching or pressure-washing, the coating sits on the surface, looks perfect for about a year, then the hot tires lift it. We diamond grind every floor.
What does a garage floor cost?
It comes down to three things: square footage, how rough the slab is going in, and which system you pick. Crack repair and grinding is where most quotes surprise people, so we tell you about it up front. You get your exact number in writing, itemized.
Will it peel where I park?
That's hot tire pickup, and it's the number one failure in this category. It's a prep problem, not a coating problem. Ground and primed properly, the floor stays put.
Can you do it in winter?
Epoxy needs a warm slab to cure properly. Ask us about your garage — if it's unheated, we'll tell you honestly whether it's worth waiting for spring.
What if my concrete is cracked?
Most garage slabs have some cracking. We fill and repair before coating. If a slab is too far gone to coat, we'll tell you that instead of taking the job.
What do you cover besides garages?
Basements, shops, commercial floors, and exterior steps and porches. Garages are most of what we do.
How long before I can drive on it?
Foot traffic the day after the final coat, vehicles a couple of days after that depending on the system and the temperature. We give you the exact window for your job before we start.
