Concrete Calculator

Use our Concrete Calculator to find an accurate estimate of both toe volume and weight of concrete that you will need to fill a certain area, based on the shape and size of the area that needs to be filled. We suggest that when you purchase the resources needed, you buy slightly more than you have estimated you will need, just in case.

Slabs, Square Footings, or Walls


Hole, Column, or Rounding Footing


Circular, Slab or Tube


* Note that our Concrete Calculator uses the stats of premixed cement density, which is 2,130 kg/cubic meters, and 133 pounds/cubic feet in order to calculate the weight of concrete which is required. It's also important to note that the density of concrete will differ depending on the type of concrete you are using.

While there are a range of concrete types, Portland cement is what most people refer to as "concrete". This is because it is the most commonly found type and is the most used construction material in the world. When being used, the concrete is usually mixed along with sand or fibers, as well as other materials that are meant to reinforced. You are able to purchase pre-mixed concrete in 60 or 80-pound bags. If you are in need of a large amount of concrete, you will be able to ask for a concrete mixer truck to deliver your order to your house, or wherever it is needed.

One of the most important steps of using concrete is the mixing stage. It's important that the concrete mixture be mixed thoroughly in order to create the best quality of concrete. After it has been mixed properly it will become a paste that can then be applied to the necessary areas, and will gradually harden. In order for the concrete to settle properly and retain its strength, it should be in a humid environment which is at a reasonable temperature. The best way to achieve this environment is to cover the concrete with plastic sheeting, or if the area is too large to do that try spraying water on it every day. This is important over the first three days of the concrete being placed and can take a couple of weeks before the concrete has reached its maximum strength.
