Concrete costs $4–$8 per square foot on average. This means you’ll pay $1,600–$3,200 for a 20-by-20 foot concrete slab, depending on the slab’s thickness and concrete type.
How Much Is It to Pour a Concrete Slab?
The cost of pouring a concrete slab varies depending on the size, shape, and complexity of the job. For an average-sized single-car garage, the cost of pouring a concrete slab can range from $2,500 to $5,500. This includes the cost of materials, labor, and other related expenses.
The size of the slab is a major factor in determining the cost. A larger slab requires more material, and more labor, leading to a higher cost. The shape of the slab is also important—a slab with a curved edge, for example, is more labor intensive and thus more expensive. In addition, if the area is uneven or requires additional excavation or grading, the cost can increase.
The type of concrete used is also a factor. Standard concrete mix is the least expensive option, but for a more durable slab, a higher-grade concrete mix may be used. In addition, reinforcing materials such as rebar may be used to increase the strength and durability of the slab. This will add to the cost.
The cost of labor is another important factor. The complexity of the job and the experience of the contractor will also affect the cost. If the contractor is experienced and performs the job
