Combining the best in jointless floor slab technology and Helix Micro-Rebar concrete reinforcement enabled this facility to be placed with no control joints. Both the 6″ thick warehouse slab and 5″ thick office slab used only 9 lbs. per cubic yard of Helix Micro-Rebar along with 100 lbs. of Komponent shrinkage-compensating cement additive to achieve this innovative joint free slab solution. Unlike shrinkage reducing admixtures, the Komponent system, when installed as directed by the manufacturer, does not just reduce but eliminates shrinkage in the slab. Helix Micro-Rebar provides strength to the slab similar to rebar, but also increases the concrete’s flexural strength (Modulus of Rupture), allowing for thinner or more crack resistant slabs.

Integrating these two high-performance technologies allowed for the elimination of traditional reinforcement saw cut joints, and the need to seal and maintain control joints. The combination also reduced the need for construction joints, improved project schedule, and reduced labor costs for the floor slab installation. The elimination of the saw cut joints makes the slab significantly stronger given the joints are the weakest part of a conventional slab. Luke Pinkerton, CTO and Founder of Helix Steel, said, “The approach finally eliminates the tradeoff between thickness and strength, yielding thinner slabs that are stronger than conventional method slabs.”
