Miami’s Diesel Shop Epoxy Flooring
Truck and heavy equipment bays take weight, fuel, DEF and fluid that comes out of an engine still hot. 343 Epoxy builds diesel shop floors across Miami-Dade, Broward, Palm Beach and the Keys that hold up to all of it.
What a Truck Bay Does to Concrete
A diesel shop floor carries more than any other floor we coat. A loaded tractor parks on it. Jack stands put an axle’s worth of weight onto four small steel feet. Transmission jacks roll across it on hard casters, and sooner or later somebody drops a brake drum on it. Bare concrete takes that for a while, then it starts to spall at the bay doors and crack where the stands sit.
Then come the fluids. Engine oil, diesel, hydraulic fluid, coolant, gear oil and DEF all end up on the slab. Concrete is porous, so it drinks them. After a few years the slab is dark, oil-soaked and slick, and nothing you put on it will stick until that contamination comes out.
The part most people miss is heat. Oil drained from an engine that just came off the highway is hot. Steam cleaners and hot pressure washers hit the floor at temperatures a standard garage epoxy was never built for. Ordinary coatings soften, blister or let go when they take hot fluid over and over. That is why we spec a diesel bay differently from a car shop.
What lands on a diesel bay floor
- Hot engine oil and gear oil at drain time
- Diesel fuel and hydraulic fluid from leaking lines
- DEF, which dries into a white crust if it sits
- Coolant, brake cleaner and degreaser
- Point loads from jack stands, tongue jacks and lifts
- Dropped drums, hubs and hand tools
- Steam cleaning and hot pressure washing
The Shop, Zone by Zone
Service bays
The thickest build in the building. Urethane cement or a heavy broadcast system with texture, carried up the wall as a cove base so washdown water stays off the drywall.
Pits and trench drains
Edges get detailed by hand. The coating stops clean at drain grates and pit lips, because a sloppy edge is the first place fluid gets under a system.
Parts and tire room
Lighter traffic, heavy shelving. Epoxy with a broadcast handles rack feet and pallet jacks, and a light color makes part numbers easier to read on the bottom shelf.
Office and drivers’ area
Drivers walk through here in the same boots they wore in the bay. A cleaner finish that still has grip keeps tracked-in diesel from turning the hallway slick.
Picking a System That Takes Hot Fluid
For the working bays our first choice is usually urethane cement. It goes down much thicker than a roll-coat epoxy, it takes impact well, and it tolerates thermal shock, which is what happens every time hot oil or steam hits a cool floor. It is also more forgiving of slab moisture than a thin epoxy film, and Miami slabs are rarely bone dry.
Where the heat stays low, like the parts room, the tire area or the hall to the office, a 100% solids epoxy with a broadcast and a chemical-resistant topcoat does the job well. A lot of diesel shops end up with two systems that meet at the bay line. We plan that seam so it lands where nobody drags a jack across it.
Every bay gets texture. Diesel and hydraulic oil on a smooth coating is like ice. We broadcast aggregate into the topcoat so a tech in work boots keeps his footing when the floor is wet with fluid. You pick how aggressive: coarser in the bays, finer in walkways that get mopped more often.
Getting Oil Out of an Old Shop Slab
Most diesel shops we walk are not new buildings, and the slab has years of fluid in it. Grinding opens the surface, but oil sitting deep in the pores keeps wicking back up and breaks the bond from below. So prep starts with heavy degreasing on the worst spots, then diamond grinding to the profile the system calls for. Badly soaked areas get an oil-tolerant primer, and concrete that is too far gone gets cut out and patched before anything is coated.
Spalls at the bay doors get filled and ground flush. We test for moisture before we write the spec. Slabs around Miami sit close to the water table and push vapor up through the concrete, and a coating laid over that can blister and peel even when everything above it was done right. Prep is the part you never see once the floor is done, and it is where most failed shop floors went wrong.
Coating the Floor While Trucks Still Get Fixed
Walk and test
Zach walks the shop, tests the slab for moisture and marks the oil-soaked areas. You tell us which bays you can give up and when.
Phase the bays
We split the floor into sections so part of the shop keeps working. Trucks move to one side while we prep and coat the other.
Prep and coat
Degrease, grind and repair, then the system goes down with the texture and cove base that zone needs.
Cure, then work
Hot work and heavy trucks wait for the full cure. We tell you when each section can take foot traffic, then vehicles, then hot fluid.
Keeping It Clean, and What the Warranty Covers
Daily care is simple. Squeegee standing fluid toward the drains, use a degreaser that suits the coating, and run a floor scrubber if the shop has one. Do not let DEF sit and dry. It rinses off easily while it is wet and leaves a crust once it hardens. Wipe up brake cleaner and fuel when you see them instead of letting them puddle overnight.
Every 343 Epoxy floor carries a 5-year warranty on materials and installation. We work with ChemTek, Smith’s Paints and Floor Guard products, and we write down which system went into each zone so you know what you have. If your shop also runs pickups and vans through lighter bays, our auto shop epoxy page covers that side of the building.
