The stretcher block is the most common CMU shape. It is the standard rectangular unit used for the body of most masonry walls and is available in widths from 4 inches to 16 inches to match different wall thicknesses and load requirements.

What is a bond beam block used for?

A bond beam block has a continuous horizontal channel that holds reinforcing steel and grout. It is used to create reinforced horizontal courses at floor lines, at the top of walls, and below roof loads, which ties the wall together and improves structural performance.

How do CMU dimensions work?

CMU dimensions are listed as width by height by length and are quoted as nominal sizes that include a 3/8 inch mortar joint. The actual block is 3/8 inch smaller in each direction, so a nominal 8 by 8 by 16 unit measures 7-5/8 by 7-5/8 by 15-5/8 inches.
