Providence Commercial Concrete

Commercial Concrete Sealing

Commercial concrete sealing is the cheapest hour we spend on your property and the one people skip until the sidewalk out front starts shedding like a bad sunburn. Road salt and freeze-thaw are what get you here. Water soaks into open pores in November, freezes, expands, and by March your loading dock has that popcorn texture nobody can un-see.

We clean the slab, let it dry a solid day or two, then roll or spray a penetrating silane-siloxane sealer that soaks in instead of sitting on top like floor wax. Two coats on anything taking plow blades or forklift wheels.

Most exterior work wants a refresh every three to five years, less if trucks are on it daily. When Providence Concrete Company seals a lot, we do it in late spring or early fall, above fifty degrees and no rain for 24 hours.

Commercial Concrete Construction

Commercial concrete construction is footings, foundations, slabs on grade, loading docks, ADA ramps and curbing, and most of what decides whether it lasts happens before a single truck backs in. We compact the subbase in lifts, set rebar on chairs instead of pulling it up mid pour, and put down a vapor barrier under interior slabs so you aren't chasing moisture for the next twenty years. A typical 6 inch warehouse slab goes 4,000 psi, with control joints cut every 10 to 12 feet within about 12 hours of the pour.

Skip that saw cut and the slab picks its own cracks. It always picks wrong.

As commercial concrete contractors working from Allens Ave to Olneyville, we schedule pours around the weather, and Providence Concrete Company crews handle the foundation work under the building too, not just the flatwork around it.

Commercial Cement Flooring

Commercial cement flooring is the slab your whole operation stands on, and most of the trouble I get called about started before anybody backed a truck up. Skip compaction on the subgrade, or lay the vapor barrier loose under a warehouse off Allens Ave, and two winters later you've got a map of hairline cracks and a forklift that thumps at every joint.

Every floor the Providence Concrete Company crew pours starts with one question: what rolls across it? A pallet jack and a 6,000 pound lift truck want different thicknesses and different joint spacing. We proof the base, set the retarder tight, keep steel up off the ground, and saw the control joints inside the first day so the slab cracks where we told it to.

Thickness, mix design, floor flatness and joint layout are what move the price on commercial concrete work like this.

Commercial Concrete Floor Coatings

Commercial concrete floor coatings live or die on the prep, not on what's in the bucket. Before any epoxy or urethane goes down, we diamond grind the slab to an open profile and test it for moisture, because a slab pushing vapor will lift a coating off in sheets by spring. That's the step some commercial concrete contractors skip when the schedule gets tight, and it's the reason you see floors peeling like a bad sunburn a year later.

What we put down depends on what runs across it. A warehouse floor off Allens Ave gets a flake or quartz broadcast under a urethane topcoat for forklift wheels and dropped pallets. A busy kitchen gets urethane cement, which handles hot water washdown and grease without softening.

Figure two to four days for most floors at Providence Concrete Company, light foot traffic the next morning, racking and equipment back around day five.

Commercial Polished Concrete

Commercial polished concrete is grinding, not waxing, and that difference is the whole job. We start coarse, usually 40 grit metal diamonds, to open the slab and settle how much stone you want showing: a light cream finish, salt and pepper, or full aggregate exposure like a terrazzo. Then we work up through resin grits, drop in a lithium densifier to harden the surface, and finish anywhere from 800 for a satin look to 1500 and up for the mirror. On most floors we cover a couple thousand square feet a day, sections at a time, so your Federal Hill dining room or Valley Street brewery can keep half the space open.

Skip a grit and you get swirl scratches that only show up at night when the track lights hit them. Every polish at Providence Concrete Company begins with a hardness and moisture read, because a soft, wet slab will never hold gloss no matter how many passes we make.

Commercial Sealed Concrete

Commercial sealed concrete is the choice when you want the slab itself to be the finished floor: no tile, no coating, just a densifier soaked in and a penetrating sealer over it. We put it down in warehouses off Allens Ave and in shops that would rather mop than re-grout. The densifier reacts with free lime in the slab and hardens the surface so forklift wheels and pallet jacks quit chewing dust out of it. Seal a green or greasy slab without that step and you get a cloudy film peeling in sheets by the second winter, once road salt starts riding in on everybody's boots.

Two coats, and light traffic back on it the next day. Grinding is what moves the number, since old patches, saw cuts and grease decide how much prep comes first, and my Providence Concrete Company crews grind before anything else gets poured on.

What the job involves

What the job involves is mostly the part nobody ever sees. Before we pour a square foot of commercial concrete, we're stripping topsoil, compacting the subgrade in lifts and setting a gravel base, because a slab is only as good as what's underneath it. Then forms, rebar or mesh up on chairs, a 4,000 psi mix, screed, float, and control joints cut within about twelve hours of the pour. Cut those late and the slab picks its own crack lines, usually straight across your main entrance.

A 5,000 square foot pad takes roughly a week from excavation to a surface you can walk on, 28 days to full strength. In winter we blanket and heat it, because a February pour in Providence that freezes overnight becomes a spring demolition job. My Providence Concrete Company crews run that whole sequence themselves, dig through cure.

What it costs

What it costs on a commercial concrete job comes down to four things: how much prep the existing slab needs, what the subgrade looks like once we open it up, the mix and thickness the use calls for, and whether we can pour it in one shot or have to stage it around your business hours. A loading dock apron taking box truck traffic every morning needs a thicker slab and more steel than an office entry, and it prices that way. Pouring after Halloween adds blankets and heated mixes, which is why we push winter work when we can.

Call me at (401) 394-6425 with the square footage and what rolls across it, and I'll give you a real figure rather than a guess.

Commercial concrete leveling on a settled warehouse floor is usually the cheapest fix on the list, and the one people put off longest.

Why choose us for this

You've got two or three quotes sitting on your desk, so why choose us for this? What you really want isn't a lecture on craftsmanship. You want the dock apron or the warehouse floor poured once, correctly, and off your mind for a decade.

Here's what we won't do.

We won't pad the invoice: the number on the estimate is the number, unless you change the scope.

We won't split the crew: your slab gets finished before we start anyone else's.

We won't pressure you: no sign-today pricing, ever.

We won't leave a mess: forms, washout and saw slurry leave with our trucks.

We're not the cheapest commercial concrete contractors you'll call, and that's deliberate. We spend it on base prep, compaction and joint layout, which is exactly where cheap commercial concrete work cracks by the second freeze. Estimates from Providence Concrete Company cost nothing and put you under no obligation to book.
