Belgard molds Mega-Tandem Wall block

The Mega-Tandem Mass Retaining Wall (MRW) block offers a versatile system with the natural look of stone, plus size and mechanical features enabling construction of walls up to 15-ft. high and gravity walls up to 10 ft. without reinforcing.

“The size and connectors in the Mega-Tandem MRW system allow for a gravity wall height of up to 10 ft. without a surcharge, which is ideal for wall projects where it is difficult to impossible to excavate for stabilization for a retaining wall,” said Al Pfannenstein, national retaining wall manager for Belgard Hardscapes. “This height is a sharp contrast to the traditional 3-ft. height that SRW products typically can achieve without reinforcement.” 

Pfannenstein also noted how “the structural benefits combined with Mega-Tandem’s look make it an unmatched innovation in the wall block marketplace. The design versatility … provides flexibility for better integration of retaining walls in building and landscape designs of commercial properties and homeowners’ outdoor living spaces. ”

Mega-Tandem features a patent-pending, positive mechanical connection. Reinforced polypropylene connecting members create structural integrity in curved or straight retaining and freestanding walls. Available in a 12 x 24 panel weighing 65 lb., the system has a running bond configuration so no patterns are required.

Meeting ASTM C1372 and C1262 standards, Mega-Tandem’s 8,500 psi compressive strength concrete makes it suitable across the country, even the coldest environments where it can withstand harsh freeze-thaw cycles. Moreover, it’s available in three color blends and comes in 12 different facial textures with the classic look of natural chiseled stone.
