Bartlett Epoxy Flooring brings more than 20 years of slab work to epoxy-flooring in North Aurora, from attached garages and basements to shop floors that get hosed down every shift. We open every slab with a diamond grinder or a shot blaster rather than an acid etch, so the primer bites into a real concrete surface profile instead of sitting on a smooth, sealed skin.
Before a price is final, the written scope includes a moisture test, typically ASTM F2170 in-situ relative humidity probes or an ASTM F1869 calcium chloride test. The proposal then names the product line, the number of coats and the finished thickness, so you can hold the installed floor up against the quote. Cracks, spalls and failing old coatings are mapped first, and we tell you plainly when repair or replacement has to come before any coating.
This page is about one idea that runs through the village: a floor that will be wet should be built to drain and be cleaned, not just to look good on day one. We work in homes, townhome garages and commercial bays here, and the same thinking applies at every scale. North Aurora happens to have an unusually clear source for that idea, and it starts below ground.
A Working Limestone Mine Under North Aurora
Conco at Interstate 88 and the Fox River
Not every homeowner knows it, but North Aurora has a working underground limestone mine. The Conco operation near Interstate 88 and the Fox River appears in MSHA’s records as Conco Western Stone, Mine ID 1102931, an underground metal and nonmetal mine producing crushed limestone. An Illinois State Geological Survey paper says it has mined limestone and dolomite underground since 1991.
The operator is registered in the village’s own business directory as LaFarge (Amrize Conco) at 105 Conco Street, Amrize being Holcim’s North American spin-off. We have no relationship with Amrize or the mine, and we have not seen how its surface buildings are floored. What interests us is the rule that governs floors on mine property, because it says something useful about any floor that gets wet.
MSHA, Not OSHA, on Mine Property
Most commercial floors we coat answer to OSHA’s general-industry rules. A mine does not. Under the federal Mine Act, mine property is regulated by the Mine Safety and Health Administration, and MSHA writes its own housekeeping standards for underground metal and nonmetal mines in Part 57 of Title 30. Surface mines have a twin rule at 56.20003.
That matters to anyone pricing work on such a site, because the floor duty comes from a different rulebook with different wording. It also means a contractor cannot hand over a floor and call it compliant. We install coatings; whether a workplace meets MSHA’s housekeeping rule is the operator’s ongoing duty, judged by how the space is run every day.
Limestone Fines on Every Surface
Limestone fines are the signature mess around any quarry or crushing operation. They ride out on tires and boots, settle on shop floors, and turn into a gritty paste when wet. That paste acts like fine sandpaper underfoot and under cart wheels, which is why a thin, soft coating wears through to bare concrete in the traffic lanes long before the edges show any wear.
On abrasive floors like these we lean toward a 100% solids epoxy base with a quartz aggregate broadcast and a hard-wearing topcoat. When the topcoat starts to dull in the lanes, it gets resurfaced rather than left to wear down to dusting concrete. Crushed limestone is also a common driveway and parking surface, which brings the same dust into ordinary garages, a point we return to below.

Clean, as Dry as Possible, and Drained: 30 CFR 57.20003
What the Housekeeping Rule Actually Says
30 CFR 57.20003 is short. Workplaces, passageways, storerooms and service rooms are to be kept clean and orderly. The floor of every workplace is to be kept clean and, so far as possible, dry, and where wet processes are used, drainage is to be maintained and false floors, platforms, mats or other dry standing places provided where practicable.
A third clause asks that floors, working places and passageways be kept free, as practicable, of protruding nails, splinters, holes or loose boards. Read together, the three parts describe a floor that is orderly, sound and managed for water. None of that is a slip-resistance rating; the rule talks about cleanliness, drainage and where people stand.
“So Far as Possible” Is Honest Wording
We like that phrase because it admits what every wash bay operator knows: some floors cannot be dry all the time. The rule does not pretend otherwise. It asks for dry where dry can be had, and drainage plus a dry place to stand where it cannot. A coating cannot change that arithmetic, and we never sell one as though it could.
What a coating can do is support the operator’s job. A sealed, non-porous surface releases fines to a squeegee or hose instead of holding them in open concrete pores, and a coating laid to follow the slab’s fall lets water leave rather than pond. Those are real gains, but drainage and standing places remain the operator’s responsibility.
Where the Rule Reaches Past the Mine
Strictly, 57.20003 applies only to underground metal and nonmetal mines. We still borrow its logic for car wash bays, food plant rinse areas, dealership service bays and any garage that takes in melting slush. The question is the same in each case: where does the water go, and where does a person stand while it goes there?
North Aurora has plenty of those floors. The Hansen Boulevard auto row is a cluster of service bays, and a 2021 petition to expand Gerald Hyundai described an addition of 12,220 square feet including 24 additional bays. Bay floors like those see hose-downs, dripping undercarriages and winter brine, which is the same kind of wet work the mine rule has in mind.
Wash-Down Floors That Drain, With Standing Places That Stay Dry
Reading the Slope Before Anything Is Coated
A coating follows the concrete under it. If a bay slab dishes away from its trench drain, a glossy topcoat will simply show the pond more clearly. We map low spots, cracks and spalls before quoting, and when the fall is wrong we say so, because fixing slope is a concrete repair, not a coating job.
Where the fall is sound, the system is detailed to let water reach the drain. Coating is carried to the drain body’s edge rather than stopped short where a lip would hold water, and cove details at walls are formed so wash water cannot track behind the base. Grinding dust is pulled into a vacuum at the machine instead of being rinsed toward the drain.
Dry Standing Places, Not Just Texture
The rule’s phrase is dry standing places: false floors, platforms or mats where practicable. We point that out to commercial owners because texture in a topcoat is no substitute for a raised spot to stand on at a wash station. A coated floor takes platform feet and heavy matting without trouble, and we plan those positions with you before the broadcast goes down.
Where a broadcast is wanted, we specify it by name, quartz aggregate or vinyl flake, with the topcoat that locks it in, so the finish is written into the proposal rather than promised. That texture hides wear and gives the topcoat body. It does not make a wet floor dry, and we will not describe it as if it did.
Scheduling Around a Floor That Never Closes
Industrial and service floors rarely get a quiet week. We phase work around operating hours, with overnight and weekend windows, so one bay or zone is down while the rest keeps running. Cure timing follows slab temperature and the dew point spread at the surface, not the calendar, which matters in a hosed bay where the concrete runs cold and damp.
Wet slabs also hide moisture problems, so we test before pricing rather than after a failure. A bay that has been hosed for years may carry more moisture in the concrete than its surface suggests, and moisture is the first warranty exclusion we name. If readings call for it, a moisture-mitigation primer goes into the scope in writing.
Stone Dust and Slush in a North Aurora Garage
Gravel Drives and What Rides In
The same pairing of grit and water reaches homes. A garage at the end of a gravel or crushed-stone drive takes in fine stone dust in dry months and gray slush laced with rock salt and calcium chloride all winter. Ground into a soft finish, that mix scratches and dulls it quickly, and brine left standing works at the edges.
Our garage systems are chosen to stand up to that winter load: a ground slab, a 100% solids epoxy or urethane cement base, a full broadcast and a polyaspartic topcoat that resists hot tire pickup. Applied the mine rule’s way, the garage stays dry where it can and drained where it cannot, with a clear squeegee path across the slab.
Ranch Garages in Lincoln Valley
Lincoln Valley on the Fox, the age-targeted ranch community on the former Fox Valley Country Club site, is built around single-level homes with two-car garages, and the garage is usually the everyday way in and out of the house. That makes the garage floor part of the daily walking path, not just a place to park. The association plows and mows; the floor is the owner’s.
For those floors we pay attention to the edges and the step. A coating is terminated cleanly so it leaves no trip lip at the apron or the slab joint, and the step up to the house door gets the same broadcast as the floor. A dry mat inside the door is the household version of the mine rule’s dry standing place.
Basements That Have Seen a Backup
North Aurora has offered an Overhead Sewer Grant Program meant to prevent basement flooding from sanitary sewer backups, covering 75 percent of the cost up to $6,000, with a licensed plumber and a Fox Metro permit required. Restoration costs such as carpet, tile and drywall are not reimbursed. In 2013 the village engineer said the backup issue involved 100 to 150 homes.
A coating has no part in that fix. We read a basement for past water before quoting, because a coating does not stop seepage, a backup or a sump that cannot keep up. Once the plumbing is right, a sealed floor wipes down quickly after a spill, and we tell you which warranty exclusions apply, starting with moisture vapor transmission and hydrostatic pressure.
Whatever the room, home jobs over the Illinois threshold get a written contract and the Home Repair: Know Your Consumer Rights pamphlet before grinding starts. Products are chosen inside the Illinois VOC limits for floor coatings, which bind whoever applies them.
