Built on a Solid Foundation
Service
Concrete polishing grinds the slab with progressively finer diamond abrasives, then densifies and polishes it to the sheen you choose. The result is a durable, low-maintenance floor with no coating to peel. Core Floorings Inc installs mechanical polishing systems in warehouses, retail environments, commercial buildings and industrial facilities across Chicagoland and Northwest Indiana.
Two choices define a polished floor: how deep the grind goes, which sets how much aggregate shows, and how glossy the final surface is. Industry charts describe four aggregate classes, A through D. Sources differ slightly on terminology, so we confirm the exact definitions in your specification before work starts.
Most commercial and industrial floors use a low to medium gloss with light aggregate exposure. A salt-and-pepper look (Class B) is common, and lower gloss also helps slip resistance.
| Class | Look | Approximate cut |
|---|---|---|
| A | Cream finish, very little aggregate | Minimal |
| B | Fine aggregate, salt and pepper | About 1/16 inch |
| C | Medium aggregate | About 1/8 inch |
| D | Large aggregate | About 1/4 inch |
Polished concrete is the slab itself, ground and densified, so there is no applied film to wear through or peel. The densified surface resists dusting and wear, the finished floor reflects light, and routine upkeep is low. That combination suits warehouses, showrooms, stores and plants where the floor works hard every day.
If your floor needs color, chemical resistance or marked work zones, a resinous system may fit better. Our epoxy and coating systems cover those requirements.
The slab's condition decides how much work polishing takes. A heavy cream layer needs more grinding before aggregate shows, softer concrete wears tooling faster, and a wavy slab may need a leveling pass first through our floor leveling service. Pits and divots uncovered during grinding are filled, but cracks stay visible even after filling.
High slab moisture can also cause densifier and coating problems, so we check moisture conditions up front. Damaged joints and cracks are best handled before polishing through concrete repair.
We look at hardness, cream thickness, flatness, cracks and moisture to plan the grinding depth.
Joints, cracks and defects are repaired so they do not interrupt the finished surface.
Heavy diamond tooling removes surface material and sets the aggregate exposure.
A densifier hardens the surface so it resists dusting and wear.
Finer resin-bonded diamond grits bring the floor up to the specified sheen.
Every floor is different, so we price each project from the site, the slab and the spec. These are the factors that move the number. Send us your project for an itemized bid.
