The Alto-Shaam warehouse expansion required exceptional coordination, advanced finishing techniques, and an unwavering commitment to quality to deliver a flawless floor system that supports modern automation and sets a new benchmark for industrial concrete performance.

Of the 85,000 total square feet, 60,000 met a F-min 60 flatness standard. Each 7-inch-thick slab used 4,000-psi concrete with two layers of wire mesh for reinforcement and long-term durability. Work was completed in 22 pours, each approximately 15 feet wide and 100–200 feet long.

To meet the superflat specification, the crew used custom forms for precise alignment, a truss screed for the initial strike-off, and a bump cutter to refine the levelness. Finishing was completed with a large pan trowel machine, producing a smooth, uniform surface ready for high-precision material handling.

All slabs were wet-cured for 7 days to ensure proper hydration, surface strength, and crack resistance.

The finished floor exceeded performance expectations, delivering a high-strength, exceptionally flat surface designed for long-term reliability in Alto-Shaam’s advanced warehouse environment. The project shows outstanding teamwork, quality control, and attention to detail from Marriott Construction and Riv/Crete Ready Mix.
