Grain Silo Coating & Repair

South Dakota & NATIONWIDE Grain Silo Repair

For grain silo repair, farmers count on NIJAC Roofing & Insulation. Grain elevators are a major means of crop management across the agricultural industry. The constant filling and emptying of silos puts them under a lot of pressure. South Dakota’s broad temperature range and often unpredictable weather only add to that stress. Without proper maintenance and timely grain elevator repair, farm harvests are at risk. Silos will eventually weaken and become structurally unsound. To effectively protect grain harvests, farmers and elevators must be diligent with scheduled maintenance and timely grain silo coating and repair.

The Economical Choice for Grain ELEVATOR Repair

At NIJAC, we understand that damaged grain is lost money. So, we’ve helped scores of farmers and commercial grain businesses protect their investment for years to come with our specialized elastomeric coating and roofing systems. While there are other types of coatings on the market, they don’t have the durability and longevity of our products. Other contractors who apply them don’t have the knowledge and experience of NIJAC. Lack of experience leaves other systems prone to deterioration due to environmental factors. What saves you money in the short-term, may end up costing you an entire elevator full of grain.

NIJAC uses flexible and durable elastomeric coatings, required for the grain elevator repair of national grain storage facilities. These features make them an effective cover for cracks and pinholes that lead to moisture damage in stored grain. Spalls and cracks are also the main entry point for insects and pests, such as mice. When clean, dry grain is moved into a dry silo, the possibility of spoilage of the product greatly decreases, while storage life increases. Our specially trained crews understand the particulars involved in roofing and silo coating. We seal and waterproof grain silos from the top down, repairing cracks, spalls, pinholes, insulation and more.

Frequently Asked Questions About Grain Silo Coating & Repair

What are the benefits of using elastomeric coatings for grain silo repair?
Elastomeric coatings protect grain silos by creating a flexible, seamless, and completely waterproof barrier that seals cracks, spalls, and pinholes. Unlike standard paint, industrial elastomeric coatings contract and expand with extreme temperature shifts. This prevents moisture infiltration, stops pest entry, blocks UV radiation, and significantly extends the lifespan of the storage structure without the massive capital expense of a total replacement.

How often should a grain silo be inspected and coated?
Commercial grain silos and elevators should undergo a professional visual inspection at least once a year, ideally 3 to 4 months prior to the fall harvest prep season. While high-quality industrial elastomeric coatings applied by specialized contractors can last for many years, proactive annual inspections catch micro-fissures and joint deterioration before structural failure or crop spoilage occurs.

What causes concrete grain silos to crack and deteriorate?
Concrete grain silos deteriorate primarily due to three environmental and mechanical factors:

  • Hydrostatic Internal Pressure: The constant structural stress from filling and emptying thousands of bushels of grain.
  • Freeze-Thaw Cycles: Moisture seeps into porous concrete, expands as it freezes, and causes the surface to fracture, leading to concrete spalling.
  • Structural Settling: Natural shifting of the earth beneath the heavy foundation over time, which causes hairline fractures to form along the silo walls.

How do you repair cracks and spalls in a concrete grain elevator?
NIJAC repairs concrete grain elevators using a rigorous, multi-step structural sealing process:

  1. Surface Preparation: High-pressure washing to remove dirt, loose concrete debris, and old, failing coatings.
  2. Structural Patching: Filling deep concrete spalls and structural cracks with specialized high-strength repair mortars.
  3. Primer Application: Applying an industrial-grade bonding agent to ensure the finish coats adhere permanently.
  4. Elastomeric Top-Coating: Spraying a heavy-duty, flexible elastomeric membrane from the top down to encapsulate and waterproof the entire structure.

Can elastomeric coatings prevent grain spoilage and pest infestations?
Yes, elastomeric silo coatings directly prevent grain spoilage and pest infestations by eliminating the entry points for water, insects, and rodents. By bridging cracks and sealing micro-pinholes, the coating prevents moisture from causing internal mold, rot, and hot spots. Keeping the internal storage envelope completely dry optimizes the storage life and preserves the market value of your grain harvest.

Is it better to repair and coat a silo or replace it entirely?
Restoring a grain silo with advanced elastomeric coatings is highly recommended over replacement because it costs a fraction of the price of new construction and minimizes facilities downtime. Total silo replacement requires massive capital expenditure and months of structural demolition. A professional roof restoration and wall coating seal the asset against the elements instantly, offering an exceptional return on investment (ROI).

Does NIJAC offer grain silo repair services outside of South Dakota?
Yes, NIJAC provides commercial grain silo coating and elevator repair services nationwide. While we are heavily rooted in South Dakota and the Midwest grain belt (including Iowa, Minnesota, North Dakota, and Nebraska), our specialized crews and mobile equipment rigs are fully equipped to deploy to agricultural and industrial facilities across the entire United States.
