Designed for steep, sloping hillsides and other structural challenges, the Vertica Pro® retaining wall system can be built to virtually any height in incredibly tight spaces – thanks to an impressive 4-degree batter, built-in alignment locators, and a near-vertical rise for less excavation and land loss. Typically used with geosynthetic reinforcement, Vertica Pro blocks meet or exceed industry standards for strength and durability.  DOT approvals vary by state.
