Cost Estimate for 13'x13' x6"

Purchasing ready-mix concrete is by far the easiest way to mix concrete for medium to large projects and can even be used on smaller projects as well. We have provided a cost comparison between ready mix and DIY concrete premix bags to give you a rough ballpark estimate.

Bag Cost Estimate

Pre-mixed concrete bags cost on average $3.50 per 80lb bag. Using pre-mixed bags to cover 169 sq ft at a depth of 6", the estimated cost is $493.50
$493.50
for 141 x 80lb bags

Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 169 sq ft at a depth of 6", the estimated cost is $338.69

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 - 3.1 cu/yd concrete = 6.9
6.9 x $17.00 = $117.30
$338.69 + $117.30 = $455.99
$455.99

**Cost assumes subbase and general prep is done.

Concrete Extras

A well-compacted subbase provides a strong foundation for concrete to lay on. We recommend you contact your nearest concrete supplier for their recommendations on whether you need a subbase, base depth, and rock type.

With a brief look, a 13x13 area at 6 inches deep, you would need approximately 4.44 tons or 3.13 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 169 sq ft area, this may roughly cost $94.64 for wire mesh, $507.00 for thicker wire rebar mesh and $21.97 for fiber mesh.

*Reinforcing for 10 inch pours and under.
How to Calculate Concrete Amount for 13x13 x6"
13 * 13 = 169 sq ft
6 / 12 = 0.5 ft depth
169 * 0.5 = 84.5 cu ft
84.5 / 27 = 3.12962962963
= 3.13 cu/yd
How to Calculate Concrete Weight
3.12962962963 * 3590 = 11235.37 lbs
Density of concrete used 2130 kg/m3or 133 lbs/ft3.
