American agriculture operates some of the most challenging environments for any building material or protective coating. Grain storage facilities, livestock confinement buildings, manure storage systems, chemical storage areas, and agricultural water storage all present combinations of chemical attack, mechanical wear, moisture, and temperature extremes that rapidly degrade unprotected surfaces. Polyurea has emerged as a practical and economical solution for a wide range of agricultural facility applications, and the rural markets it serves represent significant opportunity for polyurea applicators.
Grain Storage Facility Applications
Commercial grain storage facilities — elevators, flat storage warehouses, and on-farm bins — require protection against grain dust abrasion, moisture infiltration, and the corrosive byproducts of grain storage including mold, insect activity, and the organic acids produced during grain decomposition. Polyurea linings in grain storage facilities are typically applied to concrete floors, lower wall sections, and pits to create cleanable, impermeable surfaces that prevent moisture uptake into the concrete and make grain residue cleanup more efficient.
NSF-compliant polyurea formulations are required for grain storage applications where the coating will be in contact with food grain. Grain elevator operators are increasingly specifying polyurea for pit and boot section linings where the combination of abrasive grain and wet conditions rapidly destroys unprotected concrete. Typical grain storage polyurea applications use 60-100 mil systems over properly prepared concrete.
Livestock Confinement and Manure Management
Livestock confinement buildings — swine, poultry, dairy, and beef — are among the most corrosive environments in agriculture. Ammonia from manure pits, hydrogen sulfide from anaerobic decomposition, and high humidity create conditions that attack concrete, steel, and conventional coatings aggressively. Polyurea in livestock facility applications must provide chemical resistance to these environments while maintaining adhesion under constant moisture exposure and the mechanical abuse of equipment and animal traffic.
Manure storage lagoons and holding pits — particularly above-ground concrete or steel structures — benefit from polyurea lining to prevent leakage and soil contamination. Environmental regulations in many states require secondary containment for liquid manure storage structures above specified volumes, creating a regulatory driver for polyurea lining adoption similar to the industrial secondary containment market. Applicators working in agricultural environments typically need to be comfortable working in strongly odorous conditions and should consult applicable OSHA standards for hydrogen sulfide exposure limits.
Agricultural Chemical Storage
Farms and agricultural dealers store a wide variety of chemicals — herbicides, pesticides, fertilizers, and fuel — that require compliant secondary containment. Polyurea is an excellent choice for agricultural chemical containment because of its chemical resistance, its ability to be applied as a seamless lining to complex shapes (concrete block walls, formed concrete pads with berms), and its rapid return-to-service that minimizes disruption to farm operations.
Applicators should carefully review chemical resistance data for the specific polyurea formulation against the chemicals stored in the containment area — agricultural chemicals vary enormously in their aggressiveness, and a formulation that works well with liquid fertilizer may not be appropriate for concentrated herbicides or fuel.
Farm Water Storage and Irrigation Infrastructure
On-farm water storage — cisterns, ponds, reservoirs, and irrigation canal linings — represents a significant polyurea application opportunity in agricultural regions. Concrete cisterns and ponds deteriorate over time from freeze-thaw cycling, root intrusion, and biological fouling, and polyurea rehabilitation is typically far less expensive than replacement. NSF 61-certified polyurea is required for potable water storage applications; non-NSF systems may be appropriate for irrigation water storage depending on the downstream use.
Irrigation canal linings using polyurea or polyurea/foam hybrid systems can dramatically reduce water loss from seepage in earthen or deteriorated concrete canals — an important economic and environmental benefit in water-stressed agricultural regions. Several member companies in the Mountain West Chapter specialize in agricultural water infrastructure applications, leveraging the region’s extensive irrigation systems.
Market Access and Business Development for Agricultural Applications
Agricultural polyurea work requires building relationships with farm operators, agricultural lenders (who often drive capital improvement decisions), and farm supply cooperatives. County extension service agents and agricultural engineers at land-grant universities are valuable resources for understanding the technical challenges facing farmers in a region and for building credibility with agricultural clients.
Farm work often requires flexibility in scheduling — planting and harvest seasons create periods where farm access is limited, while the off-season (winter in most regions) may be the best time for facility improvement projects. Understanding these seasonal rhythms and positioning your business accordingly is part of successfully serving the agricultural market.
