Häufig gestellte Fragen

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).
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.
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.
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.
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.
