OAKDALE, Minn. ?EUR??,,????'??? Contractors, specifiers and architects have quickly discovered the biggest design limitation of working with most random-pattern segmental retaining walls: the inability to build walls taller than four feet high. Fortunately for landscape professionals VERSA-LOK Mosaic Retaining Wall Systems has stepped forward with a random-pattern system capable of producing ?EUR??,,????'??tall walls?EUR??,,????'?? with geosynthetic reinforcement. Thanks to a 10-inch-high panel built with three distinct retaining wall units (one Standard, one Cobble and two Accent units), Mosaic systems provide a level surface every 10 inches ?EUR??,,????'??+ something other random-pattern systems cannot claim, the company says. This level surface is crucial for optimal installation of geosynthetic reinforcement and ?EUR??,,????'??tall wall?EUR??,,????'?? construction. The end result is faster, easier, installation. Even though Mosaic walls are built using a repeating panel, they still retain a rustic, natural, stone-like appearance. Each Mosaic panel can be assembled using any one of four different unit configurations, lending a weathered look to the wall that is growing increasingly popular among architects, specifiers and building owners around the country.
