With a 24×24 concrete slab, you have approximately 576 square feet so you would need 10.66 yards of concrete.
Now the question is what you can put on this size slab of concrete and what is it going to cost.
No matter what type of building you are going to put on your land, it is going to need a foundation, which is what a concrete slab will be used for.
How much does a 24×24 concrete slab cost?
On average you can figure about $3.500 but there are a lot of factors that go into that price. You need to see what is included in the price and then figure into your budget any extra costs plus extra for unexpected expenses.
In this article, we will cover the breakdown of the price of a 24×24 concrete slab, the different types of concrete you can choose from, and what material makes up the concrete slab.
By the end of this article, you will have an idea of the cost for this size concrete slab.

How Much Does A 24×24 Concrete Slab Cost?
On average, you can figure that a 24×24 concrete slab will cost approximately $3,500 when you factor in the material, labor, and thickness of the slab.
On the low end, it could be $2.500 or as high as $5,000.
Included in the price would be the rebar for support, the wood frame to hold in the concrete as it hardens, and the fiber mesh to help reinforce the concrete.
Some prices even cover labor, but it depends on the contractor.
Cost Of Materials
The cost of the materials for this size concrete slab averages $4.00 per cubic foot.
To figure out how many cubic feet are in 576 square feet, which is what a 24×24 concrete slab is, you will need to know how thick you want the slab to be.
- Four-inch thickness would equal 192 ft3 cubic feet and would cost without labor, $768.00
- Six-inch thickness would equal 288 ft3 cubic feet and would cost without labor, $1.152.00
In addition to this cost, there is also the cost of the necessary equipment. This is what it would cost if you did the pour of the slab yourself.
When you let the contractor do the work, they will also have the necessary equipment and you do not have to worry about doing the hard work.
Cost Of Labor
On average, the cost of labor is $45.00 per hour but the actual cost will depend on the contractor you hire.
Some contractors will charge per square foot instead of hourly. If this is the case, you can expect to pay $5.35-$10.55 per square foot to do the job.
This is the average price for a concrete slab that is four inches thick.
What Are The Materials Of A Concrete Slab?
Concrete is composed of coarse and fine aggregates, cement, and water. How much cement and water you use will determine the durability, strength, and workability.
The aggregates are generally composed of crushed stone, sand, and natural gravel.
Different Types Of Concrete:
There are five different types of concrete that you can choose from.
1. Ready-Mix Concrete
This type of concrete is mixed at the plant instead of at the site. The concrete will either be re-mixed when it gets to the site or mixing it in transit using a cement truck.
The cost for this type of concrete is $119.00-$147 per cubic yard. On average, for a 24×24 concrete slab that is four inches thick, you will need only 7.11 cubic yards.
There are some companies that if you need less than 10 cubic yards, you may be charged an additional cost per cubic yard to get it to 10 cubic yards.
This can average an extra $53.00 per cubic yard.
2. Roller-Compacted Concrete (RCC)
This type of concrete has the same components as regular concrete and is made from cement, water, and aggregates.
The mix is driver, which will allow compaction with a roller without the cracking risk. This costs approximately $90.00 per cubic yard.
3. Asphalt Concrete
This type of concrete has two components, which are aggregate and asphalt concrete. Approximately 95% of the concrete is aggregate.
This is the type you would mostly see in a parking lot or on a driveway. This can cost between $7.00-$13.00 per square foot.
4. Conventional Concrete
You can get this type of standard concrete in many different ways, such as mixing it yourself at the site or having a professional do it, pre-mixed, or precast.
This mix-it-yourself is the one that is most used for home projects but is not really suitable for such a large project.
5. Stamped Concrete
This is a concrete that has textures and patterns to look like stone, brick, or other materials. It is not something you would normally use as a foundation for a barndominium.
This averages $8.00-$12.00 per square foot but can cost as much as $18.00 per square foot. It depends on the design, thickness, and how much you need.
| Concrete | Low | Average | High |
| Ready-mix | $846.00 | $640.00 | $1015.00 |
| Roller-Compacted | $590.00 | $640.00 | $812.00 |
| Asphalt | $4,608.00 | $5,760.00 | $7,488.00 |
| Conventional | $576.00 | $3,456.00 | $4,800.00 |
| Stamped | $4,608.00 | $6.912.00 | $8,000.00 |
How To Estimate The Cost Of A 24×24 Concrete Slab?
To estimate the cost of a 24×24 concrete slab you would need first to get several estimates from contractors in your area and do a comparison to get an estimate.
| Item | Estimate Cost |
| 24×24 concrete slab including materials and labor | $3,456 |
| Labor | $45.00 per hour |
| To pour concrete | $15.90 per square foot |
| Concrete slab | $4.00 per cubic foot or $900 before labor costs |
Summary
Although a 24×24 concrete slab is a little small for a barndominium, it would be good to use for a detached structure or addition.
The answer to the question how much does a 24×24 concrete slab cost, the answer is approximately $3.500.
In the article, you can see how to estimate the cost, what labor and material would cost, and more to help you figure into your budget the cost of this size concrete slab.
I'm James, your barndominiums advisor. Several years ago, I had no idea what barndominiums were. Although I'd spent over 10 years in the construction industry, the first time I heard about barndominiums was when I saw my neighbor building a new-style home. That was the first barndominium I've ever seen, and I found it so fascinating that I wanted to learn more about them.
