GRAIN BINS

DG Hot Rubber Sealant delivers flexible hot rubber sealing systems for grain bins that protect foundations from water intrusion, air loss, and corrosion while accommodating structural movement.

Hot Rubber Sealing for Grain Bins

DG Hot Rubber Sealant specializes in high-performance grain bin sealing systems designed to protect grain bins from water intrusion, air leaks, corrosion, and structural movement. Our hot-applied rubber grain bin sealant creates a seamless, flexible barrier at the bin base and foundation ring, helping prevent grain spoilage, rust on galvanized steel, and cracking of concrete floors.

Engineered to expand and contract with temperature changes and loading cycles, our grain bin waterproofing systems maintain a durable seal year-round in demanding agricultural environments. Serving farms, grain companies, co-ops, grain elevators, and ethanol plants nationwide, DG Hot Rubber Sealant supports complete grain bin maintenance by improving fan and dryer efficiency, reducing air loss, and extending the service life of grain storage structures. Our proven grain bin sealer technology delivers long-term protection and reliable performance where rigid sealants fail.

Our Process

Before anything else, we make sure our customers understand that our sealant is not tar. DG Hot Rubber Sealant uses a hot-applied rubber system heated to approximately 400 degrees, allowing the material to fully bond and penetrate the surface. Unlike tar, which dries out, hardens, and becomes brittle, our rubber sealant remains flexible and durable over time.

Staying flexible is critical because grain bins move—both with temperature changes and as bins are filled and emptied throughout the season. Our hot-applied rubber expands and contracts with this movement, maintaining a continuous seal without cracking or separating.

Led by Gary King and Danny King, with over 20 years of hands-on industry experience, our grain bin foundation sealing process follows proven methods developed through real-world application. Each project begins with a thorough cleaning of the bin foundation using high-pressure washers and wire-bristle brushes to remove dirt, debris, and contaminants. The surface is then fully cleared using power blowers to ensure proper adhesion.

Once prepared, a primary base coat of hot rubber sealant is brush-applied, followed by a secondary, thick-poured layer that forms a heavy-duty, flexible seal. This system is engineered to withstand structural movement, prevent cracking, block water intrusion, and deliver long-term protection to the bin foundation.
