How Much Does a 30×50 Concrete Slab Cost? | Pricing Important Factors

Pouring a 30×50 concrete slab involves a lot of work, but it’s a necessary step when building a 30×50 barndominium.

Before you get started, you may wonder, how much does a 30×50 concrete slab cost? The answer depends on a variety of factors, including where you live and the thickness of the slab.

With a six-inch slab with standard features, you can expect to pay between $6,000 and $12,000 for material and labor. The national average of concrete slab costs to install a slab foundation is $6 per square foot, resulting in a cost of $9,000 (1500 square feet times $6 = $9,000).

What Does a Standard 30×50 Concrete Slab Include?

A standard concrete slab comes with the following details:

• 3,000 PSI concrete with 3/4-inch crushed stone
• Six-inch-thick concrete slab
• Fiber mesh reinforcement in the concrete
• A row of 1/2-inch rebar around the perimeter
• Temporary wood form with 2×6-inch lumber
• A contractor and laborers

Keep in mind that your 30×50 slab may not include the same features listed above. For example, if you pour a four-inch foundation instead of a six-inch foundation, you will pay less.

How Much Does a 30×50 Concrete Slab Cost? Breaking It Down

A 30×50 concrete slab covers 1500 square feet of space. To determine the cost of your barndominium foundation, you need to multiply the total square footage by the estimated cost per square foot.

The cost per square foot depends on a variety of factors, including

• Your location
• The thickness of the slab
• Optional features
• Site preparation work

Your location has a large impact on the total cost of your project, as material and labor are cheaper in some areas. The cheapest states for material and labor include Oklahoma, Mississippi, and Nebraska. The most expensive states include Hawaii, California, and Washington.

The thickness of the slab is another consideration. A four-inch slab saves about $0.74 per square foot compared to the cost of a six-inch-thick concrete slab.

You can also add optional features, such as reinforced wire mesh. Replacing the standard fiber mesh with a wire mesh material improves the durability of the concrete.

Additional site preparation work may also be necessary, even if you have already paid for site prep. Before pouring the foundation, you may determine that the land requires additional grading, which may cost about $0.60 per square foot.

DIY Versus Hiring a Contractor for a 30×50 Concrete Slab

DIY barndominium kits are a popular option for those that enjoy hard work and the satisfaction of building something with their own hands. However, pouring a foundation is one of the most important stages of construction. Without a strong foundation, your barndominium may suffer from structural issues in the future.

If you decide to go the DIY route, you are likely to save money. The base cost of material for a 30×50 concrete slab is between $2.83 and $5.47 per square foot. The total cost may range from $4,245 to $8,205. However, hiring a contractor may cost between $6 and $8 per square foot, bringing the price range to $9,000 to $12,000.

The biggest cost is the material. A six-inch slab costs about $3.57 per square foot while a four-inch slab costs about $2.83 per square foot. You may also decide to add a vapor barrier ($0.50 per square foot), wire mesh ($0.40), or thicker edges ($1). To get an estimate of the cost of pouring concrete, you can use a concrete slab calculator to help determine costs.

The bottom line is that the cost of a 30×50 concrete slab varies depending on the options that you select and where you live. If you want to cut costs, you can pour a thinner slab and handle the work yourself. If you want a foundation that can stand the test of time, be prepared to pay a little more.
