How this works and common questions

About this tool

The face of one unit is its length plus the joint, times its height plus the joint. The wall area is divided by that face. Waste is inside the same division.

How it works

Add the mortar joint to the unit length and to the unit height. That face divides the wall area. The waste percent is included before the single round-up.

Rules

The same count works for bricks and for blocks. You type the unit size. Verify with your local code or a professional. Ballpark estimate, check before you buy or quote.

Questions

How is the count found?

Wall area divided by the face of one unit plus the mortar joint on the length and the height, then rounded up.

Where does waste go?

The waste percent is inside that same division, so the count rounds up once.

What is the example?

A 10 by 8 foot wall, a 7.625 by 2.25 inch unit, and a 0.375 inch joint is 549 units before waste.
