Polished concrete
20 years of experience installing millions of square feet across Montana, North Dakota, Wyoming and Idaho — retail, warehouse, university, DOT, military and custom residential.
Twenty years on the floor
Isaac Diaz has installed millions of square feet of polished concrete across Montana, North Dakota, Wyoming and Idaho. Two decades of delivered projects have built lasting partnerships with leading general contractors and architectural firms throughout the region.
That work spans custom residential design‑build, large retail, warehouses, universities, multiple primary schools, DOT facilities and government military installations — along with corporate contracts for Walmart and Home Depot. Certified over the years by multiple chemical applicators and by industry standard leaders including the CPAA and the American Society of Concrete Contractors.
Every floor starts with the slab you already have. We will tell you straight which exposure class that slab can realistically reach, and what it costs, before anyone signs anything.
What we install
Polished concrete
Mechanically ground, honed and polished to a specified gloss and aggregate exposure, then densified for abrasion resistance. Built for high‑traffic commercial, institutional and industrial floors.
Finished & sealed
Grind and seal, burnished finishes, densifiers and hardeners. The cost‑effective route when the schedule or the existing slab rules out a full mechanical polish.
Joint filling & repair
Two‑part semi‑rigid polyurea filler in saw‑cut and construction joints, shaved flush after cure. Joint edges carry wheel traffic without spalling. Drain patches and surface repairs handled before polishing starts.
Decorative concrete
Acid stain, dyes, saw‑cut patterns, borders, and seeded glass or stone aggregate. Custom design work for showrooms, lobbies, restaurants and residential interiors.
Aggregate exposure & pricing
Polished concrete is specified by how much aggregate the grinding exposes. More exposure means deeper cuts, more diamond tooling and more labor — so exposure class is what actually drives cost per square foot. The floors below are ours.
Polishing stays up in the cream paste at the slab surface. Little to no stone shows. Fastest install, lowest cost, and the most forgiving on a slab you cannot cut deep.
The cut goes past the cream into fine sand aggregate for an even speckled field. The most commonly specified commercial finish, and the best balance of look and cost.

Cut deep into the slab to expose coarse stone edge to edge. The most dramatic finish and the most tooling and labor to reach — and it needs a slab placed with that in mind.
Always ask for a mock-up
Colour shifts between classes, and not by a little. A slab that looks grey as a cream finish can turn brown once the paste comes off and the sand and stone underneath are exposed. Aggregate type, size and gradation vary by region, so no chart or photo — including the ones above — predicts exactly what your slab will look like.
The published standard is clear on this: the mock-up should be done on the actual slab being polished, not off site. We do that on every job before full production starts, so you approve the real floor rather than a sample of someone else's.
Ranges are budget pricing for planning. Final cost depends on square footage, slab condition and flatness, floor prep, joint fill, dyes and site access. Classes follow the Concrete Polishing Council aggregate exposure standard — exposure is a property of the slab as it was placed and finished, measured across a randomly placed 10 × 10 foot square, so not every slab can reach every class — specified floor flatness (FF/FL) matters when choosing one. Floors specified at a high gloss, or with heavy pore structure, generally need grouting to hit the spec. Talk to us before the slab is poured and we will help you get the one you want.

We build to published industry standards, not to whatever the last contractor called “polished.” These are the documents your architect, engineer or general contractor can specify against.
Specifications
- ACI 310.1‑20 — Specification for Polished Concrete Slab Finishes, the reference spec an architect or engineer can apply to any polished slab
- CPC Appearance Chart (PDF) — the four gloss levels, measured by DOI per ASTM D5767
- CPC Aggregate Exposure Chart (PDF) — the Class A / B / C standard behind our pricing
- CPC Glossary — shared vocabulary for bid documents
Certification
- CPAA certified applicator
- Certified by multiple chemical manufacturers
Bringing a pre‑construction checklist to the table before the slab is placed is the cheapest way to protect a polished floor budget. Ask and we will walk your team through it.
