If you are making a concrete slab, it is crucial that you know how to compute costs. You can use a concrete slab as flooring for a barndominium, garage, or warehouse. You can also make a concrete slab for your driveway. If you are building a large warehouse or barndominium, a 100×100 concrete slab is ideal for flooring.
Computing a concrete slab’s cost can be complicated. You need to take into consideration the various characteristics of a slab. You should also know the different materials and pieces of equipment you need to make a slab. We aim to train you how to compute a concrete slab’s cost so you can prepare an accurate budget anytime you need to make one.

What Factors Determine the Cost of a 100×100 Concrete Slab?
Various factors affect a 100×100 concrete slab’s cost. The most important factor is the concrete slab size because the larger the slab, the more materials you need. This means you need to spend more money making a large slab than a small one. If you hire a contractor to make the slab, the contractor will most likely charge you more to make a large one because it will take longer.
The condition of the site where you will make your concrete slab will also affect the cost of your slab. To properly make a 10,000-square-foot concrete slab, you must ensure the site is clear of rocks, rubbish, weeds, and other debris. You can hire a contractor specializing in clearing construction sites to accomplish this. A concrete slab is also more effective when built on even ground.
How Much Does a 100×100 Concrete Slab Cost?
Let us discuss the different characteristics of concrete slabs and how they influence costs.
The thickness of a concrete slab affects costs because a thicker slab requires more materials. However, there are instances when a thick concrete slab is unavoidable. The thicker the concrete slab is, the stronger it is and the more capable it is of handling heavy loads. So, if you plan on using a concrete slab as flooring for a workshop or a large garage, a thick concrete slab should support the weight of heavy equipment and many vehicles.
|Thickness||Cost per square foot|
Making a concrete slab involves inclusions. An inclusion can be a material, a tool, or a piece of equipment that is required to make a concrete slab. A reinforcing bar or rebar is an example of an inclusion. Putting rebar on a 10,000-square-foot concrete slab can help increase its tensile strength and make it more durable. However, using rebar can increase a barndominium’s cost because it is an additional cost. A wire mesh is a cheaper alternative to rebar. Putting wire mesh in a concrete slab will make it more durable, just like rebar. A wire mesh should be enough for a thin concrete slab to make it strong for its purpose.
|Site preparation||$1-$2 per square foot (2)|
|Concrete Rebar||$1.40 – $1.85 per 2 feet (3)|
|Wire Mesh||$0.28 per square foot (4)|
With Additional Features
If your floor plan includes a basement, you will need more than just a bare concrete slab. Basements are notorious for being damp and accumulating moisture. This can damage any furniture, appliances, or valuables you plan on storing in your basement. Moisture can also help encourage mold and mildew growth, which can damage equipment made of wood or fabric. In addition, mold and mildew can result in respiratory problems for the occupants of your barndominium.
|Vapor barrier||$0.50-$0.70 per square foot (5)|
|Stamped concrete||$9 – $20 per square foot, inclusive of materials (6)|
|Stained concrete||$2 – $4 per square foot, staining only (7)|
100×100 Concrete Slab Cost Breakdown
Let’s analyze the cost breakdown of a concrete slab. This will help you understand which component greatly impacts your expenses.
Concrete Bag Cost Estimate
If you are making a 100×100 concrete slab, you will use a large amount of concrete. A bag of concrete costs between $4.50 and $27 (9). Prices depend on the mixture type and the bag size you are buying.
Labor Cost Estimate
A concrete slab measuring 10,000 square feet will use up much manpower, so expect to rack up a considerable tab in labor expenses. Labor rates for making a concrete slab are between $2 and $3 per square foot (10). However, you might have to pay more if you hire a veteran because they charge more than contractors with less experience.
Truck Cost Estimate
Wet concrete costs between $125 and $133 per cubic yard (11). Wet concrete gets delivered on concrete mixer trucks, so you’re sure you’ll receive properly-mixed concrete. However, if your site is outside the supplier’s service area, you might have to shoulder fuel surcharges of between $40 and $50 per truckload (8).
How Do You Calculate the Cost of a 100×100 Concrete Slab?
Now that we have discussed the details of concrete slabs and how they affect pricing, it’s time to teach you how to compute costs. You will see below some price cost averages. You can use these to compute costs using several methods.
The first thing we need is to calculate the volume of concrete you need to make a 100×100 concrete slab. Using this calculator, we know that a 6-inch thick 100×100 concrete slab requires 185.185 cubic yards of concrete. After adding a 10% waste allowance, you will need 203.7 cubic yards of concrete. The National Ready Mixed Concrete Association estimates that a cubic yard of concrete costs $137, so expect to pay $27,906.9 for wet concrete.
It is also possible to compute a concrete slab’s cost on a per-square-foot basis. One square foot of concrete that’s 6 inches thick costs $6.20 (1). By multiplying $6.20 by 10,000 square feet, we know the total cost should be around $68,200, including the 10% waste allowance.
Should You DIY or Hire a Contractor for Your 100×100 Concrete Slab Project?
Although it is tempting because it will be cheaper to do it yourself, we strongly advise hiring a contractor. Contractors know precisely what to do to ensure that your concrete slab gets done correctly.
Concrete slabs are critical structures associated with many construction projects, so you’ll likely need one when building a barndominium, shouse, or pole barn home. This makes it important to know how to calculate a concrete slab’s cost. With this knowledge, you can accurately compute a 100×100 concrete slab’s cost to prepare a proper budget.
