Estimated Concrete Volume

19.519 cubic yards

527 cubic feet

Estimated Weight of Concrete

## 35.04 tons

Covering 1054 sq. ft. at 6" depthChange dimensions

Optional 10% extra concrete

for waste allowance

10% = 1.95 cubic yards

Total Concrete with 10% = 21.47 cubic yards

for waste allowance

10% = 1.95 cubic yards

Total Concrete with 10% = 21.47 cubic yards

## Cost Estimate for 34'x31' 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 1054 sq ft at a depth of 6", the estimated cost is

**$3,066.00****$3,066.00**

for 876 x 80lb bags

## Truck Cost Estimate

Ready-mixed concrete costs on average $108.22 per cubic yard delivered. Using a concrete truck to cover 1054 sq ft at a depth of 6", the estimated cost is

0.5 x $17.00 = $8.50

$2,112.29 + $8.50 =

*6 inch pours and under.

**Cost assumes subbase and general prep is done.

**$2,112.29**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.

0.5 x $17.00 = $8.50

$2,112.29 + $8.50 =

**$2,120.79****$2,120.79**

## 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 34x31 area at 6 inches deep, you would need approximately **27.72 tons** or **19.52 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 **1054 sq ft area**, this may roughly cost **$590.24** for wire mesh, **$3,162.00** for thicker wire rebar mesh and **$137.02** for fiber mesh.

How to Calculate Concrete Amount for 34x31 x6"

34 * 31 = 1054 sq ft

6 / 12 = 0.5 ft depth

1054 * 0.5 = 527 cu ft

527 / 27 = 19.518518518519

= 19.519 cu/yd

How to Calculate Concrete Weight

19.518518518519 * 3590 = 70071.48 lbs

Density of concrete used 2130 kg/m

6 / 12 = 0.5 ft depth

1054 * 0.5 = 527 cu ft

527 / 27 = 19.518518518519

= 19.519 cu/yd

How to Calculate Concrete Weight
