Hollowcore planks can be manufactured up to 45-feet long to form wider column-free interior spaces than other building materials allow. Hollowcore floor and roof systems are compatible with steel, masonry, cast-in-place or precast wall systems, making them ideal for large open spaces like parking garages, warehouses, and commercial buildings.
The offsite production of precast components can shorten construction schedules, especially when compared to cast-in-place. Production of hollowcore can happen while the construction site is being prepared, with all required customizations, including unique angles and mechanical penetrations, being done off-site. Hollowcore is delivered ready-to-install and can be installed in most weather conditions, leading to fewer weather delays.
Hollowcore requires no curing time after installation, providing an instant, stable work deck for following trades.
Hollowcore can be installed in construction sites with limited clearance. County Prestress & Precast’s talented truck drivers have extensive experience overcoming staging challenges when delivering our products to job sites, which helps erectors install precast planks in sites with minimal clearance between nearby structures.
Hollowcore is advantageous for installation in warehouses after the envelope and roof have been installed, or dense urban areas with only a few feet of clearance between neighboring structures. Offsite production of concrete planks also eliminates the need for large staging areas.
Hollowcore podiums offer high fire ratings and sound absorption. In multifamily applications, hollowcore limits the transmission of vehicle noises from below-grade parking structures into the residential and commercial spaces above. The inherent fire resistance of concrete provides a multi-hour fire separation between the parking and living space, which helps meet building code requirements and protects occupants in the event of a fire.
