Concrete is placed over a base of gravel that has been supported by 2×4 or 2×6 boards. The crew removes the formwork after the concrete dries, leaving a slab in its final shape.
Although the terms cement and concrete are often used interchangeably, the two are different materials. Concrete is a combination of various ingredients, such as cement, and is evident and flexible. Concrete can be made into an infinite number of shapes, textures, and colors. It is possible to go beyond 100 years just by taking good care of it, the time if it is so.
Generally speaking, pouring a concrete slab may cost you a sum of 4 to 8 dollars per square foot. The total price of concrete that needs to be poured will depend on several things, such as the size and thickness of the slab, the labor cost, the finishing type, the project type, and the reinforcements; thus, it is your choice what would be the final budget. Know what concrete is per square foot, and how it is influenced by various factors.

Prices of Slabs of Concrete per Square Foot
A concrete slab can cost as little as 4 per sq. foot. The price can go up to 8 per sq. foot. The national average cost is approximately 6.60per sq. foot, including labor and material. The actual price, however, depends on several factors such as slab size and thickness. Reinforced concrete ranges from $10.04 to $9.29 per square foot.
Cost to Install Concrete Slab
A concrete slab of 4″ thick costs $5.35 a square foot. A 6″ slab can cost as much as 10.55 per square foot if the edges are thicker.
Labor Cost For Concrete Slabs
It takes effort and time to pour concrete or put down a concrete slab. Furthermore, one requires certain types of equipment and also skills for demolition, the pouring of concrete, reinforcement, and edging that are not typically available from the Home Depot store. According to the national average, you can expect the cost of pouring concrete to range between $2.50 and $45 per square foot. The cost of labor for stripping of forms, bracing, cleaning, and stacking on site can vary from $0.30 to $0.60 per sq. foot.
Contractors may pour slabs of concrete on-site or off-site, depending on the job size. Workers can pour small slabs, such as those needed for a hot-tub base, onsite and then ship them to the job. Workers have to pour big slabs like driveway slabs onsite.
Factors that Impact the Price of Concrete per Square Foot
The thickness and the size of the slab may have a great influence on the cost, but there are also other things that can affect the price, such as the reinforcement, the concrete, or the application. Continue reading to learn more.
Dimensions of Concrete Slab
The cost of the slab is a variable that is determined by the size of the slab. For example, a 64-square-foot slab (8×8) may cost between $278 and $495. A 40×80 or 3,200 square foot concrete slab may be as cheap as $13,888 or as expensive as $24,736.
Thickness of Concrete Slab
Ordinary concrete slabs are typically 4 to 6 inches deep (thick). A 6-inch-thick slab costs an additional $0.50 to $1 compared to a 4-inch one. This (such) thickness is the most suitable for buildings with low traffic, i.e. driveways, patios, garages, and walkways.
Driveway concrete slabs can be a maximum of 8 inches thick, as the fact that heavy cars need to be supported. The four-inch slab is approximately $5.35 per square foot, the five-inch slab is about $5.78, and a six-inch slab is appr. of $6.19.
Reinforcements
Reinforcers add a cost to the concrete slabs, but add durability, strength, and quality too. The price per square foot of reinforced concrete slabs costs $9.29 – $10.04. This is $2.69 – $3.44 more than the national average of concrete slabs.
Here are some concrete reinforcement options with their benefits.
- Installation of wire mesh or rebar: This will improve the strength and prevent cracks from forming. This type of reinforcement helps concrete driveways withstand heavy vehicles. This type of reinforcement could cost an extra $0.35 per square foot.
- Vapor Barrier: This barrier is used to separate the concrete from any soil that may be moist underneath. This type of reinforcement may add up to $0.50 per sq. foot in total costs.
- Installation of Insulation: Reinforcing concrete flooring with 2-inch styrofoam will provide insulation. This can cost an extra $1.25 per sq. foot.
- Increase the thickness of concrete slab edges: This will increase durability, but it can cost between $1.00 and $1.75 per sq. foot.

3 Types of Projects
Concrete slabs can be used for a variety of purposes in construction, ranging from the foundation of a shed, a new driveway, or even a patio. The final cost will depend on the type of project and whether or not it will require different sizes of concrete or reinforcements. Continue reading to find out how the type and application of concrete can affect its price.
Concrete Patio
Installing a 10×10 patio with a total of 100 square feet costs between $5.53 and $10.25. A 10×10 patio that is 100 square feet in size costs between $1,600 and $440 . A patio measuring 20×10 or 200 square feet will cost between $880 and $3,200.
Design factors can have an impact on total costs. A simple square patio will be more cost-effective than one with curves. The cost of the curves is higher than the square patios, even though they are more attractive.
Concrete Slab For Shed
A shed does not need to be able to withstand heavy traffic. It’s usually only 4 inches thick. The cost of concrete slabs can range from $670 to $2,690.
Average concrete prices based on shed size
Concrete Slab For Garage
The size, thickness, and presence of reinforcement will affect the price of a concrete garage flooring. The price of a 24×24 reinforced garage can accommodate two cars, and the slab thickness will determine how much it costs.
Concrete Driveways
Workers reinforce solid concrete driveways to prevent cracking because they need to support heavy traffic.Solid concrete driveways range in price from $8 to $18 per sq. foot, depending on complex patterns and finishes.
Concrete Finishes
Concrete has become more than just a functional material. Modern industrial design has led to renewed interest in concrete for aesthetic purposes. The cost of adding elaborate concrete finishes can range from 8 – 18 per square foot. These are the most common types of finishes for concrete
- Troweled Surface– A troweled surface is the simplest concrete finish. It produces a level, smooth and free of blemishes surface. This is perfect for garages, indoor spaces and walls.
- Stamped concrete finish – Workers create stamped finishes by pressing wood, plastic, or metal panels onto freshly leveled cement. This is perfect for patios and walkways.
- Exposed aggregate finish – Contractors produce this popular type of textured concrete by removing the top layer of newly poured cement to reveal decorative coarse aggregate. This finish is ideal for patios and swimming pools.
- Stenciled Finish –This finish uses paper stencils rather than specialty stamps. This finish is ideal for interior areas, walkways, and landscaping.
- Colored Finish – You can obtain colored concrete by incorporating pigments into the mixture or by staining it after it dries. Colored finishes for concrete are ideal for sports, recreation, and commercial facilities.
Using technology to speed up the cost estimation of concrete projects
Concrete is more flexible and durable when it contains cement. It can be maintained well and last for more than 100 years. You can choose from numerous colors, textures, forms, and designs. Concrete is also immune to most natural disasters due to its robust and solid composition. This reduces the cost of repair.
Various problems, including labor costs, slab size and thickness, reinforcing, finish type, and project type, can also affect concrete prices per square foot. A 50×100 slab will cost more than a 12×12 slab. Costs are also higher for thicker slabs of concrete required for driveways.
