The BuildBlock Project Estimating Tools allows you to calculate the number of blocks and courses to build your home or building. The estimates generated by this tool are for estimating purposes only and rounding may be necessary when ordering block bundles. We have designed this tool to be as simple as possible so anyone can use it for any project large or small.
This tool is only an estimate. If you have additional questions or have specialty needs, please contact our technical staff for assitance.
Below you will also find the instructions for the process that our excel file uses for the calculations so you may do the estimate manually.

How to Estimate Your Project
Follow the instructions below to estimate how many BuildBlock forms you'll need for your construction project.
Follow the instructions below to estimate how many BuildBlock forms you'll need for your construction project.
Estimate the concrete volume required by the following: Divide total square footage of wall to be formed, including corners, by 53 or 40 (for 6” or 8” forms, respectively). This equals the number of cubic yards of concrete required. Add 1.5 additional yardage for waste and the pump. (You do not want to be short on concrete. Delays are too expensive on manpower and pump costs.)
