Belgard® Hardscapes Introduces Mega-Tandem™ Wall Block

Belgard® Hardscapes has introduced the Mega-Tandem™ Mass Retaining Wall™ (MRW) block, a versatile wall block system with the natural look of stone that allows for building reinforced walls up to 15 feet high and gravity walls up to 10 feet without reinforcing.

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

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 a 12 x 24 panel weighing 65 pounds, the system has a running bond configuration so no patterns are required.

Meeting ASTM standards (C-1372 and C-1262), 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. It is available in three color blends, and in 12 different facial textures with the classic look of natural chiseled stone.

“The design versatility offered by Mega-Tandem provides flexibility for better integration of retaining walls in building and landscape designs of commercial properties and homeowners’ outdoor living spaces,” Pfannenstein said.

  1. We do not have the ability to use single wythe 6″ or 8″ clay masonry as an exposed exterior and interior sinle wythe wall and cavities filled with insulation to meet the energy code? I understand this is possible with concrete block but not brick. I love brick but not concrete block for a class medical/office building. This leaves us with our only option being cavity walls containing 2 layers of 4″ brick with 4″ or more of insulation in the cavity or brick veneer over a 2 X 6 wood stud wall with insulation to meet the energy code). Building the exterior walls twice makes no sense and an exterior wall 12″ or more thick is rediculous. I have designed and owned one of several single wythe 6″ or 8″ brick exterior bearing walls with the cavities filled with insulation. They have cofortable temperatures in the winter and are up to 4 story high medical/office buildings before the energy code. The energy code in this climate should allow a single wythe insulation filled brick with a green roof, triple pane windows or other energy devices to compensate. My 4 story office is built like this with a comfortable winter temperature, more beautiful outside, and inside than any building in Everett, WA.

    The energy saving devices could more than compensate for any temperature loss in exterior walls with an extremely more practical brick building.

    Without this option allowed in the energy code you might as well go back to using brick for fireplaces and chimneys only.>
