STREAMLINED SLAB
Authorized installer Wayne Brothers proves MEGASLAB tendencies to low carbon metrics, high load-bearing potential, plus concrete schedule and jointing optimization
In a current manufacturing facility contract with square footage in the seven-digit range, Wayne Brothers Companies is placing 6-in. thick MEGASLAB sections free of steel reinforcement, and saw cutting joints only on steel H or W column lines. Davison, N.C.-based Wayne Brothers is a key slab and industrial pavements player across the Southeast and an authorized MEGASLAB installer. It the secured the manufacturing facility’s performance slab on grade specification as an alternative to an initial 9-in. thick, reinforced design.
Wayne Brothers promoted the specification’s carbon reduction potential on three tangible factors: One-third less concrete, a 90-plus percent reduction in reinforcing steel requirements, and the ability to standardize mix designs around a binder of Type IL portland limestone with Class F fly ash at 20 percent. “The MEGASLAB solution and blended cement positioned us to report a 45 percent embodied carbon reduction versus a concrete and slab specification more typical of this type of facility,” affirms Executive Vice President of Business Management Chad Hensley, P.E. The current project extends Wayne Brothers’ growing roster of MEGASLAB installations, he adds, led by a contract involving five miles of service roads at a Kentucky plate mill for Charlotte, N.C.-based Nucor Corp., North American steel market leader.
