DOT-grade units boost overall segmental retaining wall sales

The 2017 NCMA SRW Sales Survey of U.S. and Canadian hardscape producers indicates year-over-year segmental retaining wall shipment gains of 3 percent and 6.5 percent, respectively, for 2016 and 2015. Now in its second year, the survey reflects data from 39 SRW producers or licensors spanning 178 plant locations.

Data was solicited in 8- and 6-in. height, ‘DOT quality’, ‘boundary wall’ (fences or other vertical structures not retaining soil) and ‘other’ unit categories. The DOT category performed best in 2016, with a 20 percent volume increase over the prior year, followed by moderate 8-in. high SRW and boundary wall unit growth.

“The results of this survey show the continued strength of the segmental retaining wall unit market,” says NCMA Chairman Steve Berry. “Additionally, efforts to target departments of transportation and other institutional decision-makers have helped grow the market for DOT quality products. The year-over-year increase in sales benefits all in the industry, including producers, designers, engineers, and those who supply machinery, materials, and other products to segmental retaining wall producers.”

The complete 2017 NCMA SRW Sales Survey is available for $99 (NCMA members) and $1,500 (nonmembers), and can obtained from the association, 703/713-1900,
