Elmhurst Epoxy Flooring offers epoxy flooring in Summit backed by more than 20 years in the trade, and every job begins at the slab rather than the color chart. We open the concrete with a diamond grinder or a shot blaster, never an acid etch, so the resin bonds to a real profile instead of a dusty skin. A moisture test is written into the scope before the price is final, whether the floor belongs to a garage, a basement or a working shop.
Our proposals name the product line, the number of coats and the finished thickness, so the floor that goes down can be checked against the quote. Cracks, spalls and old coatings are mapped first. When a slab needs repair or replacement before it should be coated, we tell you before anyone signs.
This page is about one kind of floor in particular: the coated shop or garage where a diesel engine lives. Modern diesels clean their own exhaust filters with heat, and the engine makers are blunt about where that has to happen. Planning a floor around that rule matters more than any color or flake choice.
A Mack and Hino Truck Center on Bulldog Drive

Service bays that run until midnight
M&K Truck Centers, listed as Chicago Mack Sales and Service, sits at 7900 Bulldog Drive inside the village and sells and services Mack, Hino and Isuzu trucks. Its location page lists service hours from 7:00 in the morning to midnight, with full service and parts. That is a long shift of heavy diesels rolling in and out of bays.
We have no relationship with M&K, and we have not seen how it runs its shop or what its floors are made of. We use it here because a truck center of that kind is the clearest example in Summit of the work a coated diesel floor has to plan around.
What a parked regeneration is
Diesel engines built to current emission rules trap soot in a diesel particulate filter, and that filter has to be burned clean from time to time. When ordinary driving cannot do it, the truck runs a parked regeneration, raising exhaust temperatures high enough to burn the soot off while the vehicle sits still. Mack technical bulletins on file with NHTSA confirm that its filter systems use parked regeneration, and one of them starts the process at 110 percent soot load.
Why the engine makers say outside
A Detroit Diesel service bulletin from October 2016 repeats one warning box throughout its pages. During a parked regeneration, it says, the exhaust gases will be extremely hot and could cause a fire if directed at combustible materials, and the vehicle must be parked outside. That bulletin covers Detroit engines rather than Mack’s own, but the rest of the trade says the same thing.
Prevost manuals call for stationary regenerations outdoors only, with the filter outlet clear of objects and people. Cummins tells drivers to point the exhaust outlet away from combustible surfaces and to confirm nothing sits on or near the exhaust before starting one. A GM upfitter bulletin advises parking at least 10 feet from anything that could burn or melt, outdoors and away from walls or buildings.

Hot Exhaust and a Resin Floor
Temperatures a coating was never meant to meet
Prevost puts exhaust components above 500 degrees C, or about 1,000 degrees F, with particulate-filter peaks up to 1,200 degrees F. A resin floor is an organic material, cured at room temperature and built for tires, foot traffic, chemicals and cleaning. It is not a heat shield and it is not fire-rated, and no epoxy, polyaspartic or urethane cement topcoat we install should be treated as one.
A heat limit is a reason, not a target
Resin systems carry service temperature limits on their data sheets, and those limits sit far below what a regenerating stack puts out. We read a heat limit as a reason to keep exhaust away from the floor, never as a number to test against a truck. In a diesel shop the answer is distance and layout, not a thicker or tougher coat.
Exhaust aimed down at a coating can soften or discolor it, and the same mistake repeated on the same spot turns into a repair that never stays fixed. The fix is upstream of the floor. Keep the heat source outdoors and the coating never has to survive it.
What the coating does well in the same room
None of this makes a coated truck floor a poor idea. A seamless, light-colored floor shows leaks quickly and cleans faster than bare concrete, and one manufacturer’s chart rates its solvent-free epoxy fully resistant to diesel and motor oil. Slip resistance comes from the broadcast and topcoat we specify, such as a quartz aggregate broadcast, not from a line on a brochure.
Laying Out a Coated Truck Shop
If we were scoping a coated floor for a diesel shop in Summit, the plan would start from where the heat goes. These are the zones we draw before the first pass of the grinder, and they matter as much as the product line.
The regen apron stays outdoors
Parked regenerations belong on an outdoor apron or a marked spot outside the building, with the stack pointed away from walls, parked vehicles and stored material. That apron is plain concrete, and we do not coat it to match the shop. The indoor floor is designed on the assumption that no truck will ever regenerate on it.
Extraction hoses stay off the coating
The Detroit bulletin also says that an engine run in an enclosed area should have its exhaust vented to the outside, which is the job of an exhaust extraction hose. Those hoses and nozzles should be rated for the temperature, hung on reels or booms, and kept off the floor between uses. A hot nozzle left lying on a coated floor puts exhaust heat straight onto the resin.
Parking a truck that just finished a regen
A truck pulled inside right after a regeneration still carries a hot filter canister and stack. Park it with both clear of mats, rubber, cardboard and stored parts, and keep the space under and behind the exhaust bare of anything that can burn or melt. We can stripe those parking spots into the floor so the habit outlasts the first week.
Working around a long service day
A shop open from early morning to midnight cannot close for a week. We would phase the work bay by bay and set cure schedules by slab temperature and dew point rather than the calendar, so each bay returns to service only when the resin is ready for a loaded truck. Grinding dust is captured at the machine by vacuum, never rinsed toward a trench drain, because Summit’s sewer carries sewage and rainwater in one combined system.
Products are chosen inside the Illinois VOC limits for floor coatings and industrial maintenance coatings, limits that bind whoever applies them. In a working truck shop we also favor systems that return to service quickly, such as a polyaspartic topcoat over a 100% solids epoxy base, when the slab and schedule allow it.
The Diesel Pickup in a Summit Garage
The same rule reaches home garages. A diesel pickup with a particulate filter can call for a parked regeneration too, and the outdoor rule does not soften because the floor is residential. Nothing here argues against coating a diesel owner’s garage. It only means the floor and the truck’s maintenance routine have to agree, the same way they do in a truck shop.
Regenerate on the driveway, not the coated slab
If the truck asks for a parked regeneration, run it outside on the driveway, with the tailpipe aimed away from the house, the garage door and anything stored nearby. The Detroit bulletin says not to interrupt a regeneration once it has started, which is one more reason to start it where it can finish. Pull in only after it ends, and park so the exhaust does not sit over a floor mat or a storage shelf.
Older slabs, salt and water
Summit’s housing stopped growing after the 1970s, with only 46 units built in the 1980s and 105 in the 1990s. Nearly every garage floor here is an existing slab with decades of wear, patches and old sealers, so we map its cracks and spalls first and choose a system that stands up to the brine and rock salt that ride in on tires all winter.
The village’s own 2024 hazard mitigation annex says most of Summit lies in the Des Plaines River floodplain. We test for moisture before any coating is priced, and we explain what the warranty leaves out before the job is sold, with moisture named first. A coating does not stop water coming up through a slab, and we will not pretend it does.
Owners, landlords and the village
In Summit, 60.9 percent of occupied homes are owner-occupied, and many of the rest sit in two-flats and small apartment buildings. An owner-landlord deciding on a shared garage floor gets the same written scope as a homeowner, and home jobs over the state threshold get a written contract and the Illinois consumer-rights pamphlet before any grinding starts.
Summit takes its name from the highest point on the old Chicago Portage, but the rules for a floor job come from the Village of Summit Building and Public Works department on West 59th Street. We check permit and contractor questions with the village before the job is scheduled, especially when a slab is being replaced rather than coated. That keeps the diesel garage, and the floor under it, on the right side of both the engine maker and the village.
