Reliable Concrete Slabs in Snellville

A slab should match what will sit on it. A shed or carport pad carries a light load, a garage floor carries vehicles, and a slab floor carries the weight of a building, so thickness and the ground under it change with the use. Building slabs are part of our commercial concrete work.

Volume drives the price, and volume comes from length, width, and thickness. A 20 by 20 foot slab at four inches thick takes about five cubic yards of concrete, before waste. Base material, forming, finishing, and delivery add to that. Get a free estimate for your slab. For a house floor or footings, see concrete foundations.

The model residential code sets a minimum of 3.5 inches for concrete floors on the ground, and four inches is common. A base of clean gravel at least four inches deep sits under the slab, with a plastic vapor barrier for a slab floor. A garage slab usually leads out to a concrete driveway.

Fresh concrete should be cured for at least three days and up to a week, and kept above 50 degrees Fahrenheit, because poorly cured concrete can lose up to half its potential strength. Hot or cold weather changes how it is protected. A concrete patio is cured the same way.

In unincorporated Gwinnett County, a building over 120 square feet needs a permit and a passed footing inspection, and its floor must be a solid surface such as concrete or wood, not gravel or dirt. Cities set their own rules, so check with your local building office before the work starts.
