Hiring concrete flatwork contractors in Montana

Concrete flatwork covers everything flat and horizontal: garage and shop slabs, patios, sidewalks, equipment pads and aprons. Most of what determines whether a slab lasts happens before the truck arrives. The subgrade is compacted, a gravel base of about four inches is placed and compacted, forms are set to grade with slope away from the building, and reinforcement, typically wire mesh or #3 or #4 rebar on chairs, is placed. Residential slabs are usually four inches thick and poured at 3,000 to 4,000 psi; anything that will see trucks or equipment goes to five or six inches. Control joints are cut at intervals of roughly two to three times the slab thickness in feet, so about every eight to twelve feet on a four-inch slab, because concrete will crack somewhere and joints tell it where. Concrete needs about seven days before foot traffic and twenty-eight to reach design strength.

What concrete flatwork work costs

Standard broom-finish flatwork typically runs $6 to $12 per square foot installed, so a 20 by 20 foot patio lands around $2,500 to $5,000 and a two-car garage slab $4,000 to $8,000. Removing an old slab adds $2 to $6 per square foot, and pumping, thickened edges or a heavy-duty six-inch pour push the number up from there.

Ranges are national and approximate; regional labor rates, material prices and site conditions move them in both directions.

Concrete Flatwork FAQ

What does concrete flatwork work cost?

What should I share when requesting a concrete flatwork estimate?

Send the dimensions, what will sit or drive on the slab, the finish you want, where water should run, how a mixer truck can get in, and whether old concrete or turf needs to come out first.

What can change the cost of concrete flatwork work in Montana?

The main cost items are square footage, thickness and mix design, and whether the truck can back to the forms or a pump is needed; excavation, gravel base, vapor barrier, reinforcement and any old concrete that has to be removed first; finish type, joint cutting, sealing and how far the crew has to travel for a small pour. A site visit helps the crew see which ones apply.

Do concrete flatwork projects in Montana need permits?

Many jurisdictions exempt small patios and walkways but require a permit for slabs that support a structure, anything in the public right-of-way, and work that changes drainage onto a neighbor. Sidewalks along a street usually have to meet city standards and ADA slope limits.
