At the time of publication, the average cost of concrete for a 400-square foot slab, the typical size for a two-car garage, ranges between $583 and $637 or between $1.46 and $1.59 per square foot. On average, contractors will put in about 13 hours of labor to finish a two-car concrete garage slab.
Basic concrete slab cost. I'll base my price on what my actual estimate would be to install a 6 thick concrete slab for one of my customers. Base cost for a 6 thick concrete slab -- $4.00 dollars per square foot --. Take the length of the concrete slab x the width of the slab to get the.total square footage. Multiply the total square footage by 4 (dollars) to get the total price. concrete slab is poured right on a gravel pad and the edges are formed with 2x4's, 2x6's, 2x8's etc. A concrete floor is poured inside a concrete foundation, ICF walls, cement block walls, I think you get the idea.
