Flake & Metallic Epoxy Flooring

Flake is our most popular garage and basement floor, a speckled, multi-color finish that hides dirt and tire marks, resists chipping, and holds up to daily foot and vehicle traffic for years. Metallic is the high-end upgrade: a marbled finish with real depth and shine, closer to a poured stone or marble look than a painted floor, and a popular choice for showcase garages, basements, and any space meant to impress.

Our epoxy installation process

Assessment and quote

We come look at the concrete, measure, and give you a written number, usually the same day you call.

Diamond-grind surface prep

Every floor is mechanically ground to bare concrete, and any cracks or damage are repaired before coating.

Coating application

Base coat, flake or metallic pigment, and a protective topcoat are applied in sequence.

Cure and walkthrough

We walk the finished floor with you and go over care instructions before we consider the job done.

Why Local Homeowners and Businesses Choose Expansive Triangle

Every floor starts the same way: we grind the concrete down with diamond tooling, not acid. Acid etching is faster and cheaper, but it only lightly roughens the surface, that's why so many garage floors you've seen start peeling or flaking within a couple years. Diamond grinding opens up the concrete itself, so the epoxy bonds to something solid instead of just sitting on top of it. Combine that with a licensed, insured crew, a 1-year labor and adhesion warranty, and quotes within 24 hours of your call or text, and you've got a floor that's built to actually last, not just look good on install day

Licensed and insured

We carry full licensing and insurance for every residential and commercial project. You are protected from the first cut to the final coat.

Six years

Six years of epoxy and flooring work across the northwest suburbs. We have seen the failures and learned how to avoid them.

Diamond Grinding

Diamond grinding means your floor is built to actually last. Cheaper contractors use acid etching.

Real warranty

A minimum one-year labor and adhesion warranty on epoxy systems. Extended coverage is available, contact us to learn more.
