Preguntas frecuentes
How do I calculate square footage for a concrete project?
Measure length and width of the pour area and multiply for surface area in square feet. For how much concrete to order, you also need slab thickness (depth).
How do I convert square footage to cubic yards of concrete?
Multiply area (sq ft) by thickness in feet, then divide by 27 for cubic yards. Example: 200 sq ft × 0.33 ft (4 inches) = 66 cu ft ÷ 27 = 2.44 cubic yards.
How much concrete do I need for a standard 4-inch slab?
For 4-inch thickness, multiply sq ft by 0.0123 to get cubic yards. Example: 500 sq ft × 0.0123 = 6.15 cubic yards. Order 5 to 10% extra for waste, spillage, and uneven subgrade.
What waste factor should I use for concrete?
Add 5 to 10%. Use 5% on flat, well-prepared ground. Use 10% or more on uneven terrain, complex forms, or lots of edges. Running short mid-pour is worse than a little extra.
How do I estimate the cost of a concrete project?
Calculate area, add waste, then enter price per square foot in Estimate Material Cost. Ready-mix concrete often runs $100 to $150 per cubic yard delivered. For cost per sq ft, divide total cost by area.
