Designed for residential or commercial use, the 2x4x3-ft. Verti-Block can be stacked higher than other blocks without using tiebacks or geogrid. It features a 5-in. relief depth, hides joints, and gives finished walls the appearance of stacked stone. It is easily stained and has a weather- and UV-resistant finish. As a light, hollow block, it requires less manpower, equipment, and transportation costs than traditional block. Verti-Crete. 801-571-2028.
