Store Your Supplies Safely
When you need sand and salt storage, we provide the structure you need. Protect your commodity and make sure you get maximum use when you invest in a fabric structure facility for your operations. At Calhoun Super Structure, we offer streamlined solutions that meet your requirements and simplify your processes. We understand how critical it is to create a safe and comfortable environment for workers and protect your valuable assets.
Make a cost-effective investment that delivers high durability and performance with a salt storage building structure, engineered to your specifications. Calhoun custom-engineers fabric salt storage buildings specifically tailored to companies and municipalities who need salt dome storage for the unique properties of salt and sand. With experience in manufacturing sand and salt storage building for townships and businesses, we help you determine the right dimensions and style of structure for your needs.
Exposure to moisture leads to clumping, waste, and lost material. Calhoun structures provide reliable coverage with ventilation to keep salt and sand dry and accessible year-round.




Built to Last
Salt and sand storage facilities are often exposed to some of the harshest weather conditions, making structural performance critical. Calhoun structures are engineered to withstand demanding environmental loads, with designs capable of exceeding 300 psf snow loads and wind speeds up to 150 mph.
Every structure undergoes a site-specific engineering review using advanced 3D Nonlinear Finite Element Analysis (FEA) to evaluate how the building will perform under real-world conditions. This detailed approach helps ensure reliable performance in regions prone to heavy snowfall, high winds, and severe weather events.
Combined with hot-dip galvanized steel framing and durable fabric covers, Calhoun structures provide long-term protection for valuable materials while delivering the strength and reliability required for municipal, industrial, and commercial bulk storage applications.
Why Calhoun
Enclosed, ventilated structures keep salt and sand dry, preventing clumping and ensuring salt is ready when needed. Our fabric allow increased air circulation preventing moisture buildup, mold, and bacteria growth.
Hot dip galvanized steel frames and componentry resists long-term exposure to salt, extending structural life in highly corrosive environments.
Maneuvering tipping trucks is critical in your industry. Our wide-span interiors have no columns, providing maximum clearance for trucks and other equipment to navigate the facility with ease.
Protecting stockpiles from rain and snow minimizes material loss and preserves usable inventory.
With a variety of structure designs and configurations to choose from, we custom-engineer your salt dome building any way you like to accommodate bulk materials, overhead equipment, conveyors, catwalks, equipment storage, and shipping and receiving equipment.
Every Calhoun structure undergoes advanced 3D Nonlinear Finite Element Analysis (FEA) to evaluate real-world wind, snow, and seismic loads. This site-specific engineering process helps ensure long-term structural performance and reliability.
Materials and design reduce ongoing maintenance requirements in tough conditions.
Calhoun’s non-conductive fabric membranes allow for more air tightness to prevent leakage of waste fuels into the environment.
Tell us about your project goals, building requirements, site location, and intended use. Whether you need road salt storage, sand and aggregate stockpile protection, or fleet vehicle protection and storage, our team will help identify the right building solution for your operation and budget.
Once we understand your needs, we review key project details including building dimensions, access requirements, fabric options, doors, ventilation, insulation, and site conditions. We also evaluate local wind, snow, and environmental loads to ensure the structure is designed specifically for your location.
After project approval, our engineering team performs a comprehensive site-specific review using advanced 3D Nonlinear Finite Element Analysis (FEA). Once engineering is complete, the steel framework is fabricated, hot-dip galvanized, and prepared for shipment alongside the fabric building system.
Calhoun offers installation services through experienced crews or can support your preferred contractor. Following installation, our team remains available for inspections, maintenance, repairs, fabric recovering, and relocation services to help maximize the lifespan of your investment.
