Nanotech enables contractor to execute jointless slabs on grand scale

Atlanta-based Sinclair Construction Group has launched the Megaslab Jointless Concrete System, crediting its design and performance potential for large slab-on-grade project owners to “ground-breaking technology paired with powerful admixtures that create an incredibly dense and impermeable slab, eliminating the need for installing control joints and their associated costs.”

In contrast to conventional or jointless-style slabs on grade with saw cut control joints at 15 ft. and 50 ft., respectively, Sinclair Construction promotes the Megaslab as an impermeable, performance alternative, free of such joints and exhibiting high tensile strength and durability for the heaviest loads and equipment.

Compared to jointless alternatives, the contractor contends, slabs with curling- and spalling-prone control joints require more maintenance and upkeep—often leading to ongoing equipment repair and reduced productivity. Conventional reinforced, jointed slabs also limit the ability to develop and place the most optimized racking and robotic schematics in current storage, distribution and manufacturing facilities.

Megaslab is a complete concrete system that utilizes nanotechnology paired with a proprietary blend of flexible admixtures and sprays. The result is an impermeable slab with exceptional tensile strength and durability for the heaviest loads and equipment. “I am confident that in due time Megaslab will revolutionize the concrete construction industry,” affirms Sinclair CEO Jason Adams. With a team of renowned industry experts overseeing extensive testing and field validation, he adds, “We’ve developed a world-class concrete product with leading edge innovation.”

Joining Adams in Megaslab design and engineering is HeidelbergCement AG and (pre-Cemex) RMC Industries veteran Sylvester Schmidt, who will lead technical support efforts as the system is commercialized. A major Megaslab installation and additional projects are planned by year’s end. Sinclair is presenting the technology as a game changer for industries or applications such as logistics, industrial, food/beverage, aviation, plus robotics-enabled automatic storage and retrieval systems.
