Frequently Asked Questions
How many standard modular bricks do I need per square foot of wall?
A standard modular brick measures 7-1/2" × 2-1/4" × 3-1/2". With a standard 3/8" (0.375 inch) mortar joint, each brick covers approximately 20.67 square inches. Dividing 144 sq in by 20.67 yields approximately 6.965 bricks per square foot of single-wythe wall. Masons generally multiply net wall square footage by 7, plus a 5% to 10% waste factor.
How much mortar and sand is needed per 1,000 bricks?
Laying 1,000 standard modular bricks with 3/8" joints requires approximately 6.5 to 7 bags of Type N or Type S masonry cement (70–80 lb bags) and roughly 0.55 tons (1,100 lbs) of clean masonry sand, or about 14 to 15 bags of pre-blended premix mortar.
