How Many Yards of Concrete in a Truck?

If you are a contractor, you have asked yourself this question at some point. The answer is complex, as it depends on several factors. Generally, a truck can hold between 15 and 20 yards of concrete. However, the concrete’s weight will affect how much one can fit. The heavier the concrete, the less it can do in the truck. It is essential to overestimate how much concrete one needs to avoid multiple trips to the concrete plant and risking running out of concrete.


How many yards of concrete do I need for a 24×24 slab?

To determine how much concrete is needed for a 24×24 slab, enter 4 inches in the thickness/depth field, 24 inches in the width field, and 24 inches in the length field. Click “calculate,” and the answer should be 7.11 yards. The Concrete Volume Calculator can also be used to determine yardage for aggregate products, which is helpful for larger projects that require multiple slabs or curved surfaces.

How many yards of concrete do I need for a 12×12 slab?

One needs to know the slab’s thickness to calculate the amount of concrete needed for a 12×12 slab. A 4-inch thick slab needs approximately 1.76 cubic yards or 47.52 cubic feet or 1.35 m3 (either 104 bags of 60lb or 80 bags of 80lb) of premixed concrete. In comparison, a 5-inch slab needs 2.22 cubic yards or 59.90 cubic feet or 1.68 m3 (either 130 bags of 60lb or 100 bags of 80lb). These are general estimates, and specific needs may vary depending on job site conditions and other factors. It is always best to consult a professional before starting any concrete project.

How much does it cost to pour a 24×24 slab of concrete?

The cost of pouring a 24×24 slab of concrete ranges from $5.31 to $10.32 per square foot, depending on the slab’s thickness and whether it is reinforced. A 4″ reinforced slab costs between $3,057 and $5,944, while a 6″ reinforced slab costs between $4,608 and $8,448. The cost of labor and materials varies depending on the location and the project’s complexity. However, one can generally expect to pay between $60 and $80 per hour for labor and between $6 and $15 per square foot for materials. To get a competitive price for one’s project, get multiple quotes from licensed contractors in the area.

What is the right thickness for a concrete slab?

The thickness of a concrete slab is a critical factor in its overall strength and durability. Whether you are constructing a residential driveway, garage floor, or an industrial setting, it is essential to determine the appropriate thickness of the concrete for the application.

Recommended Thickness for Concrete Slabs

The standard thickness for a residential construction project is 4 inches. However, you anticipate occasional heavy loads like motor homes or garbage trucks. In that case, it is recommended to increase the thickness to 5 to 6 inches. This additional thickness helps distribute the load’s weight evenly, reducing the likelihood of cracks or other damage. Even thicker slabs are often necessary for industrial settings to support heavy machinery or large storage tanks.

How to Determine the Amount of Concrete Needed

When ordering concrete, you need to specify the desired depth. The standard thickness for a garage floor is 4 inches, requiring 54 cubic feet of concrete (27 cubic yards). On the other hand, driveways and sidewalks are usually only 3 inches thick, requiring 81 square feet of concrete for every cubic yard. To calculate the square footage of your project, multiply the length by the width of the feet. For example, a ten-foot-long driveway that is two feet wide would require eighty-one square feet of concrete (10×2=20; 20×4=80; 80+1=81). You can then multiply this number by the depth of your project to determine how many cubic yards of concrete you will need.

Concrete Thickness for Driveways and Garage Slabs

Regarding concrete driveways, a standard thickness of 4 inches is recommended for passenger cars. However, a thickness of 5 inches is recommended for heavier vehicles such as trucks or RVs. It is also essential to ensure that the driveway or garage slab is sloped correctly to prevent standing water and proper drainage.

Building Code Requirements

Building codes offer requirements for the concrete mix, which vary by region. These standards are expressed in terms of “compressive strength,” the amount of water used in the combination. Higher compressive strength is generally better, but too much water can weaken the concrete. Thus, following the building code requirements for your region when pouring a garage slab is crucial.


The thickness of a concrete slab is crucial for its overall strength and durability. Whether it is for a residential or industrial application, it is vital to determine the appropriate thickness for your project. Following the guidelines and building code requirements ensures that your concrete project will be long-lasting and sturdy. For large projects, it is always best to consult a professional contractor to determine the exact amount of concrete needed.
