How do I calculate how much concrete I need for a deck slab?
- Determine how thick you want the concrete.
- Measure the length and width that you'd like to cover.
- Multiply the length by the width to determine square footage.
- Convert the thickness from inches to feet.
- Multiply the thickness in feet by the square footage to determine cubic feet.
In this regard, how much concrete do I need for a deck post?
One 80-lb bag of concrete yields . 60 cubic feet when combined with 4 quarts of water. If you're purchasing 80-lb bags of concrete, you'll need 1.66 bags of concrete. As before, since bags of concrete are only sold in whole quantities, you'll need to purchase two (2) 60-lb.
Additionally, how much does a 12x12 concrete slab cost? The average cost for a standard 12′ x 12′ shed concrete slab costs roughly: $720 – $1,200. or $6 – $10.00 per square foot.
Similarly, it is asked, how much concrete do I need for a 12x16 slab?
Concrete costs from $113 to $126 per cubic yard or between $2.83 to $3.57 per square foot depending on the thickness of the slab poured. It will cost an additional $2.52 to $2.60 per square foot for the labor.
How much concrete do I need for a 40x60 slab?
Starting with the foundation. How much does a 40×60 concrete slab cost? It would be about $8,500 to $12,000 for a 40×60 foot concrete slab, 6 inches thick. That's based on national averages of around $5 per square foot for a fully engineered, finished concrete slab, including labor and materials.
