Go big in your outdoor room designs with new Mega-Tandem Mass Retaining Wall (MRW) blocks. The versatile wall block system offers the natural look of stone with a size and mechanical structure that allow for reinforced walls up to 15 feet high, and gravity walls up to 10 feet high without reinforcement.

Mega-Tandem blocks offer structural stability, even when excavation for a retaining wall is inconvenient or impossible.

The blocks "are ideal for wall projects where it is difficult to impossible to excavate for stabilization for a retaining wall," says Al Pfannenstein, national retaining wall manager for Belgard Hardscapes. "This height is a sharp contrast to the traditional three-foot height that [segmental retaining walll] products typically can achieve without reinforcement."

Structurally, Mega-Tandem features a patent-pending positive mechanical connection. The reinforced polypropylene connecting members create structural integrity in curved or straight retaining and freestanding walls. Available in 12-by-24-inch panels weighing 65 pounds, the system has a running bond configuration so no patterns are required. The blocks use 8500 psi compressive strength concrete that can withstand freeze-thaw cycles, making them suitable for use nationwide, even in the coldest climates. 

Available in 12 chiseled-stone textures, Mega-Tandem is available in three color blends. Belgard Hardscapes | 877.235.4273 | belgard.com
