We completed this challenging project using the Techo Bloc Monumental Retaining Wall system, chosen specifically for its ability to be installed up to 10 feet high without the need for geogrid reinforcement. The limited workspace made this product the ideal solution, as we had to replace a failing existing retaining wall that was supporting an active septic system. The result is a structurally sound, visually appealing retaining wall that provides long-term stability and peace of mind in a very demanding location.
