Installation Complete: Dunn County, Wisconsin Salt Storage Dome

The GC Fabric Building Division recently completed a salt storage dome for Dunn County in Boyceville, Wisconsin. The fabric structure measures 53' x 64' and is built on durable pad and pier foundations, with integrated bunker panels to enhance material containment and handling efficiency. A key highlight of this project is the sliding steel door, which provides secure, weather‑resistant access and smooth operation—making it a standout feature for year‑round functionality.
