The conversation about the cavity in masonry wall systems, to say the least, is ongoing. There is a general agreement on the need for separation between the backside of the veneer and the exterior face of the structural backup wall. However, there is some discussion about the functions this cavity performs and their prioritization.
The theme of transportation was dominant when architecture firm Leo A. Daly designed a five-building distribution center for Dollar General in Bessemer, Alabama. Rather than opting for a conventional finish on the warehouse’s precast exterior walls, the Omaha-based design firm sought a visual way to bring the theme to life.
While heating exterior penetrations wastes energy and increases carbon emissions and operating costs, chilling interior structures reduces comfort and allows condensation and mold to form on adjacent surfaces. Therefore, one must look for an alternative solution.
When it comes to parking garages, durability is key, as they are often located in busy metro areas where closure, repair, or reconstruction can be disruptive. Time, labor, and material costs for renovation are also prohibitive. These structures are generally made from reinforced cast-in-place or precast concrete, making corrosion one of the most common challenges to durability.
