Tindall schedules production of C-I-P, hollow core slab alternative

The Tindall Superior Lightweight All-Purpose Beam (T-SLAB) is presented as the first and only system of its kind—a precast solution affording superior performance and constructability over both cast-in-place and prestressed hollow core plank. Fabricated in up to 12-ft. widths, T-SLAB seizes on arch design principles by using super lightweight concrete to serve as blocks over which structural concrete is poured, leveraging the arch effect translationally for load distribution, while capitalizing on longitudinal prestressing for total span capability. Several slab thicknesses will be available to achieve optimal spans in the 30- to 45-ft. range, supporting typical commercial and residential floor loads.
