The Masonry Estimating Guide is a "rule of thumb" calculator intended to assist users in planning for the correct amount of materials required for a particular project. It is presented in table format below and also available to download as an Adobe Acrobat PDF file. NOTE: Approximately 5% to 10% should be added to all quantities for breakage, spillage and errors.
Supreme Concrete Block, Inc. makes no guarantees to the accuracy of any estimates based on the information provided in this guide, and takes no responsibility for its use.
To help you better understand the use of this guide, we have provided the following example: If a mason needs to know how much block, mortar and sand must be purchased to erect a 20' long x 10' high wall, the Estimating Guide reveals that there are 1-1/8 blocks per square foot of wall area. The area is 200 SF, which requires 225 blocks (1-1/8 x 200 = 225 blocks). Three bags of mortar are estimated for every 100 block, therefore 6-3/4 bags of mortar are needed ((225 block x 3 bags mortar) / 100 block = 6-3/4 bags of mortar). One cubic yard of sand is required for every 7 bags of mortar, therefore, the mason must also purchase .96 yards of sand ((1 cubic yard of sand x 6-3/4 bags of mortar) / 7 bags mortar = .96 yards of sand).
