The Prestressed Group specializes in the manufacture of hollowcore floor and roof slabs for a variety of applications in low- to high-rise commercial, industrial, and residential construction.

Hollowcore precast/prestressed slabs meet or surpass the high-quality requirements of industry-wide building standards.  Hollowcore slabs have a minimum two-hour fire rating, plus they're manufactured with non-combustible materials, lowering personal risk and property damage and increasing the potential for reduced insurance premiums.

Hollowcore products allow for flexibility and versatility in adapting to other precast frames and can also combine well with structural masonry walls, steel framing, or cast-in-place framing.  Combining high-compressive strength plant-cast concrete with high-tensile stressing strands allows for thicknesses from 6" - 14" and column-free spans up to 50'.  The continuous voids are engineered to reduce weight while improving structural performance, and can also act as heating/cooling ducts and raceways for electrical wiring

The hollowcore slab's smooth ceiling surface requires caulking only on the joints and with a coat of textured paint, a professional, clean finish is achieved.
