Garage floor concrete in Brookings SD - a slab built for what you park on it

Garage floor cracked, sunken or holding water? We tear it out, rebuild the base and pour a slab sized for how you use it.

What does a new garage floor involve in Brookings?

Garage floor concrete in Brookings means pouring a new slab for your garage, usually after tearing out the old one, and how well that floor serves you comes down to how it's designed and how carefully it's built.

Most calls I get start with a floor that's cracked through, sunk by the door or holding water, or with a new garage that needs its slab. We break out and haul off the old concrete, dig down to firm ground and pack the subgrade, the ground the slab sits on, so it doesn't settle under your car. If you want more than plain gray, our decorative concrete work covers color and pattern.

The price moves with the size of the garage, whether old concrete has to come out and how thick the slab needs to be for what you'll keep on it, and your estimate puts a number on your job. The schedule mostly turns on the weather and the permit, and we sort out permits before we start, filing them ourselves or walking you through it.

What goes into a garage floor that lasts

Most of what makes a garage floor hold up gets done before the concrete truck shows up, and most of it you won't see once the slab is finished.

  • The base comes first

    If the budget gets tight, I'd cut anywhere but the base, because once concrete covers it the only fix is tearing the floor out.

  • Joints cut on time

    We cut control joints, shallow grooves that give the slab a straight place to crack, soon after the pour, because late or skipped joints let cracks wander.

  • Water that runs out

    We check where snowmelt off your car will run before setting forms, and on a sloped lot concrete retaining walls can keep dirt and runoff back from the garage.

  • Pouring at the right time

    We don't want to be finishing in the midday heat, because concrete that dries too fast ends up with a weak, dusty top you'll be sweeping for years.

Garage floor questions we hear most

How much does a new garage floor cost in Brookings?

I can't give you an honest number until I've seen the garage, because a lot of the cost sits in things I judge on site, like how much soft ground has to come out under the old slab. Hauling off old concrete, getting the truck close and any change to the driveway approach all add to it, and a plain finish costs less than color or pattern. Call (605) 401-5479 and I'll come take a look.

How thick should a garage floor be for an RV or a shop?

Garage slabs for RV storage or a shop with heavy equipment are typically 5 or 6 inches thick with reinforcement, steel set inside the concrete to help hold it together, and that's more than the code minimum. Tell us early if that's the plan, because it changes how we build the slab.

When is it too cold to pour a garage floor in Brookings?

A Michigan concrete trade group's cold-weather guide says to pour only on thawed ground that's at least 40°F and within 20°F of the concrete's own temperature. When the ground's frozen, that guide says to thaw it with ground heaters or blankets, so a cold-weather pour can take extra time before the truck comes. After the pour, keep running engines and fuel-burning heaters away from the floor for the first 24 hours, because their exhaust can leave a dusty surface on fresh concrete.

What causes cracks in a new garage floor?

Concrete shrinks as it dries and moves with the weather, so some cracking and some curling at the edges shows up on every slab, and it doesn't by itself mean the floor was built poorly. What we can control is the base and the joints, so most cracks land in the grooves we cut. I'll tell you up front that a few small cracks are normal in a sound floor, so you can judge the work with that in mind.

Do I need a permit to pour a garage floor in Brookings?

Check with the city before work starts, because Brookings issues building permits for residential projects inside city limits and on non-farm land in its joint jurisdictional area. If the job changes your driveway or its approach to the street, the City Engineer's Office has to issue a permit first, and on county land Brookings County sends permit questions to its County Development Department at (605)696-8350. When it isn't clear what applies, we check with the office for you.

How do I care for a new garage floor in its first winter?

Keep deicers off it that first winter and use sand if you need traction, which is what that Michigan group's customer tips advise. After the first winter, the guide lists magnesium chloride, calcium chloride, fertilizer and water-softener salt as things to keep off concrete, and it suggests a penetrating sealer 30 or more days after the pour, once the slab is completely dry and the weather's within the sealer's temperature range.

Why Brookings homeowners call Brookings Concrete for garage floors

I care most about what goes under the concrete, because you can't fix that later, and I'd rather you know what to expect before we start than be surprised after.

  • I come out myself

    I look over your garage and the ground in person, and I'm on site with our own crew for the pour.

  • Building since 2013

    I learned on a crew for years before starting this business in 2013, and slabs like this are what we're known for.

  • Fully licensed and insured

    That includes the contractor's tax license South Dakota requires of anyone contracting for construction work.

  • Satisfaction guaranteed

    That's our word on the job, and I'll go over the finished floor with you before the crew leaves.

  • Brookings, Madison and nearby

    We're based in Brookings and work across Madison and the cities around both, so call (605) 401-5479 to set up a visit.
