When the developers of Clarius Park Joliet industrial park decided to erect another large-scale industrial building, they turned to Insulated Sandwich Walls (ISWs) manufactured by County Prestress for their efficient installation and low maintenance requirements. ISWs are a resilient, economical, and high-performance building material suitable for a wide range of industrial and commercial uses. County Prestress manufactured and delivered 364 prestressed wall panels and coordinated with the contractor and erector to meet the project’s aggressive construction deadline.
