Our Services in South Dakota include:
Grain Silo Coating & repair
We protect your investment with elastomeric coating for grain silos, to seal leaks and cracks. This coating lasts much longer than typical coatings and is applied by our licensed staff. NIJAC installs elastomeric roofing systems that are designed to work effectively for grain silos and grain elevators.
Concrete Roof Silo Restoration
NIJAC has many years of experience in all aspects of concrete roof silo repair and restoration. Our proven track record and knowledge of proper repair have given us a name that is well known in grain elevator roof repair. We have a team of experts who can evaluate your silo, bin, or grain elevator and offer restoration recommendations.
Metal Roof Restoration
Metal roof restoration not only extends the lifespan of your metal roof but also inhibits further deterioration. Our metal roof coatings are long-lasting and highly energy-efficient and provide you with long term energy savings. We provide premier service for the following:
- Roof Coating
- Metal Roof Restoration
- Flat Roof Services
- Roof Repair Services
- Grain Silo Roofing Services
Grain Elevator Repair
Throughout South Dakota, the agricultural industry relies heavily on grain elevators to safely store and manage crops. We’re on a mission to help on-the-farm and commercial grain bins protect their products. The elastomeric coatings that we use to repair grain storage facilities are flexible and durable, and provide an effective cover for cracks and pinholes. Our specially trained crews will seal and waterproof your grain elevator from the top down, repairing cracks, pinholes, insulation and more.
SPRAY FOAM & BLOWN INSULATION
Spray foam is a premium insulator with long-term energy benefits. In addition to reducing energy costs, spray foam insulation improves air quality, reduces moisture and mold, and decreases noise pollution.
- Residential Spray Foam Insulation Services – homes, garages, and sheds
- Commercial Spray Foam Insulation Services – barns, silos, roofing, outbuildings, pump rooms, offices and businesses. We also perform services on industrial and manufacturing facilities, where temperature and moisture control are vital.
- Hybrid Insulation – The benefits of hybrid insulation include increased thermal and moisture resistance, as well as substantial money savings due to the hybrid’s tighter seal.
- Batt Insulation – Also referred to as “roll” or “blanket” insulation, batt insulation is a fiberglass product that is very flexible, can be installed quickly, and does not settle over time. It is also less expensive to install than other products.
We service nationwide for your grain elevator roofing and insulation needs.
While our home base is in Sioux Falls, our crews are fully mobile and equipped to handle large-scale restoration and insulation projects across the United States. We have extensive experience navigating the unique climate challenges of the Heartland.
