Slump Blocks

In contrast to the precise dimensions of the straight-edged precision block, slump blocks are intentionally distorted during the manufacturing process to simulate the appearance of old adobe bricks. The rustic, rounded appearance of slump block is produced by utilizing a wetter than normal mixture that is subjected to an additional compression immediately upon ejection from the mold.

When specifying concrete masonry units, the dimensions are indicated in the following manner: width x height x length. Dimensions of slump blocks are usually expressed in terms of their nominal size, which is one-half an inch greater than their actual size. This half-inch difference accommodates the standard 1/2 inch mortar joint that is utilized with precision units. For example, a unit with the nominal dimensions of 8″ x 6″ x 16″ would have actual dimensions of 7-1/2″ x 5-1/2″ x 15-1/2″.
