County Prestress’ Hollowcore is a high-performance construction material predominantly used in multifamily residential and commercial projects. Its prestressed fabrication makes it an ideal choice for roof and floor systems, as it supports high load capacities across long, column-free spans. Hollowcore endures weather and wear over a prolonged service life and enhances occupant safety and comfort with high fire and acoustic ratings.
Hollowcore is manufactured to meet the individual load and span requirements of each project, allowing for its usage beyond multifamily housing. County Prestress also supplies hollowcore for car wash bays, pedestrian bridges, and other diverse applications.
Car Wash Bays
Midwestern convenience store chain, Kwik Trip, specified County Prestress’ Hollowcore for several car wash bays as part of a recent regional expansion. The prestressed concrete planks were favored for their ability to withstand the damp, high-moisture environment without compromising performance. Hollowcore was also advantageous in forming large, open spaces for equipment to be installed on all sides of the bay while maintaining adequate vehicle clearance.
A medical campus in Minneapolis, Minnesota, specified County Prestress’ Hollowcore for the construction of a pedestrian bridge between one of its facilities and parking ramps. Hollowcore was selected for its ability to form long, column-free spans. County Prestress worked with project leaders to configure the site’s tight staging area and complete the bridge within a tight five-day timeline.
