How Much Does It Cost To Pour A Concrete Driveway


How much does a concret driveway cost?
i have a 90 ft driveway on a slope and it is gravel/dirt. i am still waiting from several contractors to give me estimates, but no one can seem to just say 90 ft long/ 9ft wide "X" amount of dollars. Does anyone have a rough estimate?

It depends on many factors. 90' by 9' =810 square feet. Now you need to know the thickness, which varies by area/local building codes/temperatures, etc. Typically it needs to be a minimum of 5 inches to handle weight of a car, thicker for trucks.

Assuming a depth of six inches [or half a foot =.50], you multiply your total sq ft times your thickness, or 810 x .50. This equals 405 cubic feet of concrete needed [volume of material].

A "cubic yard" of concrete has 27 cubic feet in it, and this is how concrete is ordered, usually down to "thirds of a yard". Example: 4 and 2/3rds yards, 1 and 1/3rd yards, etc.

You take your cubic foot number [410 in your case], and divide it by 27. This gives you your material number. This equals 15.185. Always add some for waste, I would order 15 and 2/3rds yards of concrete for your project. The delivered price per yard varies depending on your geography, additives, and small or "short load charges". A truck carries 7 cubic yards as a rule, sometimes more, but you will be charged more per yard if you order less than a full load, to make up for delivery costs.

At $110/yard delivered, your concrete cost will be $1722.60.



Now you have labor and other material costs to add to this. Labor is different from region to region. You can usually ask a "per yard" price for forming/pouring/finishing concrete. In MN, the union wage is $28/hr in Duluth, and $13/hour in Detroit Lakes, 4 hours away. For that reason, it is hard to give even a rough estimate on your total cost without knowing more factors.

There are also other costs involved, which are included in the "labor" part of the bid. Some would be: degree of slope [the steeper the driveway, the more it costs for obvious reasons], what type of reinforcement will be needed in the concrete [ie: fiber, re-bar, wire mesh, accelerant], finish of the finished project [ie:broomed finish, stains, decorative stampings or stencils], and the cost of the form boards, which are usually a onetime use expense.

Off the top of my head, your driveway would cost you $1800 [materials] + a minimum of $2000[labor] for the bare bones job in my area. Of course you could be looking at upwards of $3000 more for decorative stuff.
