Segmental pavement project activity nears double-digit growth

Gross sales for segmental concrete pavement contractors in the U.S. and Canada increased 8.8 percent in 2016 over the prior year, according to the Interlocking Concrete Pavement Institute’s 2017 Contractor Industry Survey, reflecting responses Columbus, Ohio, market researcher Industry Insights obtained from 218 small, mid-size and large companies.

“The 2015 ICPI study of concrete paver manufacturers reported a 14.5 percent increase in the number of pavers sold in the U.S. and Canada,” says ICPI Chairman Matt Lynch (Oldcastle Architectural). “This year’s survey of contractors also shows significant progress. It’s great to see that the overall industry is enjoying consistent growth and that homeowners and other end users understand the benefits of concrete pavers and slabs.”

The new 12-page guide includes extensive insight on best design and construction practice, along with a maintenance guide for common PICP distresses.

Among other key 2017 ICPI Contractor Survey findings:

  • 69.1 percent of respondents required crews to review and participate in a formal, documented safety program, an increase of 4.1 percent from 2015;
  • The greatest challenges confronting contractors include recruiting, hiring and retaining quality employees, increasing overhead costs and competition; and,
  • Average wages increased by 3.0 percent for 2016 payrolls, while 2017 levels are pacing a 3.2 percent jump.

The study also includes overall data on the specific systems contractors use to monitor and reduce crew member exposure to respirable silica, plus promotion and certification trends. In addition to reporting overall data, results are also grouped based on respondents’ length of construction season, gross sales, and number of employees during peak project activity.

Along with contractor survey findings, ICPI has released “Tech Spec 23: Maintenance Guide for Permeable Interlocking Concrete Pavements (PICP).” The 12-page piece features 36 figures and tables plus information on PICP benefits and maintenance; insight on practices to support surface infiltration; infiltration inspection and testing techniques; preventive maintenance equipment options for various PICP applications; restorative infiltration maintenance for highly clogged surfaces; inspection intervals and procedures for maintaining surface infiltration; and, winter maintenance practices.

ICPI promotes PICP as a durable, cost-effective solution for compliance with national, state/provincial and municipal stormwater regulations. The surface consists of solid, durable concrete pavers with small, stone-filled joints that allow water to flow into highly permeable, open-graded bedding, base, and subbase aggregates. The spaces among the aggregates store water and enable infiltration into the soil subgrade rather than generating surface runoff. PICP is well suited to freeze thaw climates.

“PICP has demonstrated significant runoff and pollutant reduction for walkways, plazas, driveways, parking lots, alleys, and streets throughout the U.S. and Canada,” affirms Matt Lynch. “Like all other types of stormwater control measures, PICP requires some maintenance as over time sediment accumulates in the joints. Tech Spec 23 is a highly anticipated guide designed to provide project owners, design professionals, stormwater and road agencies, plus homeowners with PICP maintenance best practices.”
