How Much to Pour a 24x24 Concrete Slab

Concrete Volume Formula:

\[ V = \frac{24 \times 24 \times D}{27} \]

Concrete Volume (cu yd):

Definition: This calculator estimates the volume of concrete needed for a 24x24 foot slab based on the desired depth.

Purpose: It helps construction professionals and DIYers determine how much concrete is required for a standard 24x24 slab project.

The calculator uses the formula:

\[ V = \frac{24 \times 24 \times D}{27} \]

Where:

Explanation: The formula calculates the cubic footage (24x24xdepth) and converts it to cubic yards by dividing by 27.

Details: Accurate concrete volume estimation ensures you order the right amount of concrete, avoiding costly overages or shortages.

Tips: Simply enter the desired slab depth in feet (typically 4-6 inches for patios, 6-8 inches for driveways). The value must be > 0.

Q1: What's a typical depth for a 24x24 slab?
A: For patios: 4-6 inches, for driveways: 6-8 inches, for garage floors: 4-6 inches.

Q2: How many cubic yards is a 24x24x4" slab?
A: 7.11 cubic yards (4" = 0.333 feet → (24×24×0.333)/27 = 7.11).

Q3: Should I order extra concrete?
A: Yes, it's recommended to order 5-10% more than calculated to account for spillage and uneven subgrade.

Q4: How much does a 24x24 concrete slab cost?
A: Costs vary by region but typically $6-$10 per square foot including materials and labor.

Q5: How long does it take to pour a 24x24 slab?
A: With a crew, typically 1 day for prep and pouring, plus 3-7 days curing time before use.
