Bag Cost Estimate
Truck Cost Estimate
Concrete trucks may also charge a "short load" fee for partially filled loads. Short load fees are charged at about $17 for every yard not used on the truck.So for a 10 cu/yd Truck Load - 8 cu/yd concrete = 2
2 x $17.00 = $34.00
$865.76 + $34.00 = $899.76

*6 inch pours and under.
**Cost assumes subbase and general prep is done.
With a brief look, a 18x24 area at 6 inches deep, you would need approximately 11.36 tons or 8 cubic yards of gravel.
Concrete reinforcing is also recommended in high traffic areas and medium to large areas. Wire mesh on average costs $0.56 per sq ft and fiber mesh costs $0.13 per sq ft.
So for your 432 sq ft area, this may roughly cost $241.92 for wire mesh, $1,296.00 for thicker wire rebar mesh and $56.16 for fiber mesh.*Reinforcing for 10 inch pours and under.
6 / 12 = 0.5 ft depth
432 * 0.5 = 216 cu ft
216 / 27 = 8
= 8 cu/yd
