Grain Covers

Custom Fabricated Solutions

GeoCHEM specializes in custom-prefabricated covers designed to protect large agricultural stockpiles from moisture and oxygen migration. These covers are tailored for:

  • Temporary & Long-Term Storage: Options ranging from lightweight temporary films to heavy-duty vinyl for multi-season use.

  • Diverse Applications: Designed for grain piles, sugarbeets, salt, and other bulk commodities requiring environmental protection.

  • Shape & Size Flexibility: Covers can be fabricated into massive, acre-sized "drop-in" panels to fit any pile geometry and minimize the need for field seaming

Core Product Line Details

1. GeoGrainMax™ Series (GMWBK, GMPWBK, GMUWBK)

The GeoGrainMax line is the flagship for reinforced grain storage, known for high tear and puncture resistance.

  • GeoGrainMax (Standard): An economical, scrim-reinforced film designed for high-strength agricultural applications.

  • GeoGrainMax Pro: Offers enhanced durability for professional-grade storage environments.

  • GeoGrainMax Ultra: The heaviest scrim-reinforced option in the series, providing maximum resistance for long-term exposure and high-wind environments.

2. GeoGrain 6, 8 & 12 Mil (GGR6WBK)

  • Construction: Economical, reinforced films.

  • Key Features: Specifically engineered for agricultural applications where puncture resistance is critical. These films balance lightweight handling with the strength needed to prevent tearing during installation and exposure.

3. GeoFresh Oxygen Barrier (GF-AB2C2)

  • Material: 2 mil, seven-layer co-extruded barrier film.

  • Technology: Produced from flexible Linear-Low-Density Polyethylene (LLDPE).

  • Function: Specifically designed as a silage and grain "underlay" or oxygen barrier. It is extremely flexible, allowing it to "cling" to the pile surface to eliminate air pockets and significantly reduce spoilage.

4. GeoProtect Series

  • Specifications: Available in 16, 20, and 30 mil thicknesses.

  • Material: Woven-coated materials designed for grain, hay, and silage. These covers are highly resistant to UV degradation and physical abrasion.

Technical Specifications & Benefits

  • Material Diversity: Products utilize LLDPE (Linear Low-Density Polyethylene) for flexibility, HDPE for chemical resistance, and EVOH layers for gas/oxygen barriers.

  • Reinforcement: Most grain covers feature a "scrim" (a high-strength internal grid) that prevents small punctures from turning into large catastrophic tears.

  • UV Protection: All outdoor-rated covers are formulated with carbon black and UV stabilizers to withstand years of direct sunlight.

  • Accessories: To ensure a complete containment system, GeoCHEM provides:

    • Tarp Grabbers: For secure anchoring without piercing the cover.

    • .Seam & Patch Tapes: For on-site repairs and joining panels
