Concrete is a cornerstone element for any home project.
For many homes, it’s literally the foundation upon which they are built. Concrete is also a key ingredient of hardscape elements to enhance your backyard; it provides a solid entrance with driveways and walkways; and it securely sets posts for fences or mailboxes.
Here’s how Quikrete’s calculators do the math for you and make home improvement projects easier.
Whether you need a slab for a concrete driveway or shed foundation, Quikrete’s concrete calculator tells you how many bags of mix you’ll need to get the job done — eliminating any worry of being short a bag or buying too many.
First, choose the desired product — popular options include Quikrete’s Concrete Mix (for larger slabs) and Fast-Setting Concrete Mix in the red bag (for smaller slabs).
The calculator determines the amount you need for a 4-inch or 6-inch slab. Just enter your slab’s square footage and it will tell you how many 40-, 50-, 60- or 80-pound bags you’ll need.
Posts and Mailboxes
Calculate how many bags you’ll need here. All you need to do is enter the depth of the hole. The calculator will generate the number of bags you need for various post and hole diameters.
Over time, cracks and crevices will creep up on your concrete. To maintain your concrete surface’s structural integrity and prevent additional damage, repair those cracks with a concrete crack sealant.
Simply enter the approximate length of the crack you will be repairing in feet, and Quikrete’s Concrete Crack Sealant Calculator will tell you how many 10.1-ounce tubes you will need for your project.
Just enter the size of the area you need to cover in square feet. The calculator will tell you how many bags you will need to cover the area at a 1/8-inch, 1/4-inch, 3/8-inch 1/2-inch, 3/4-inch, 1-inch or 2-inch depth.
And Quikrete has a mortar mix calculator to tell you how much you’ll need. Just enter the number of bricks or concrete blocks you plan to use for your project.
The calculator will tell you the number of 60-pound or 80-pound bags of Quikrete Mortar Mix you need to construct your project with a ⅜-inch mortar joint.
