Engineered Retaining Wall | Rockwood
Rockwood Classic® 8 SRW retaining wall is manufactured by Ernest Maier at our block plant in Bladensburg, Maryland. Classic® 8 is the high performance 1 square foot retaining wall specified by engineers and architects. Known for its ease of installation, strength, and versatility, professional retaining wall installers prefer Classic® 8 due to increased production per day.
Rockwood Classic® 8 is typically installed as a grid reinforced retaining wall in fill situations and cut situations with ample room for geo-grid tiebacks in the reinforcement zone. Rockwood Classic® 8 shape, known in the industry as the "dog bone", provides 'handles' for the installer taking stress out of the hand work. In installation, the open sides are filled with #57 stone serving dual purposes of drainage and locking the system together, block to block and course to course.
