For retaining walls taller than 3 to 4 feet, building codes generally require a building permit and structural wall design prepared by a qualified engineer. Independent civil engineers (P.E.) licensed in the state of the project must prepare these final wall designs. VERSA-LOK and local representatives can provide contacts for engineers with segmental retaining wall experience who are licensed in your state.
The versatility of VERSA-LOK Standard—the original solid, pinned retaining wall system—is evident in the winner of the 2007 VERSA-LOK Design Contest. Scott Van Asten of Vosters Landscaping in Kaukauna, WI, built everything but the kitchen sink using VERSA-LOK Standard in his winning design. Van Asten also won first-place in 2005.
Landscape architects have gone from building retaining walls with VERSA-LOK to building bridges—and are winning awards in the process.
The National Concrete Masonry Association (NCMA) gave its 2008 “Award of Excellence” to Seven Bridges, a master planned residential community at Platte City, MO, near Kansas City, for an arched vehicular and pedestrian bridge built with VERSA-LOK Retaining Wall Systems at the community’s gateway. The bridge was designed by Shafer, Kline & Warren, Inc. of Lenexa, KS.
