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.
The concrete slab layer can be poured alongside with the footings or it can as well be poured later on. The slab area is usually laid with a compacted base layer of gravel or rock. Slab foundation requires form materials and excavation process. The exaction cost is around $0.5 to $1.0 per square foot. The cost of constructing simple slab foundation is around $6.00 to $10.00 per square foot including the materials and labor. For complicated slab, the cost is around $15 to $20 per square foot.
