How much concrete do I need?
In order to calculate how much concrete you should purchase for a project there are two things you need to know. First you will need to find the footage the concrete will cover. For a rectangular pad, you probably already know how to do this. If you have something more complex in mind, like a curved driveway, see our Measurement page to learn an easy way to do it.
You will also need to know the desired concrete slab thickness. Generally how thick you should pour concrete requires many factors to be taken into concideration. You will need to consult your local building code before you start your project. However there is an easy way to get an idea of how thick your concrete proably should be. You still need to follow building code, but this tip will help you get a cost estimate before you go to all that trouble. Try measuring the concrete thickness of a new home under construction near your site.
Don't forget your other costs. rebar, wire, tools ect. Additional costs are not estimated by this calculator.
Once you have an idea from the concrete calculator take a minute to read the estimate page for tips on getting professional estimates. Even if you plan to do the job yourself getting a few estimates is a really good idea. Often a pro will point out costs you weren't expecting so you can take them into account.
