6 Smart Grain Storage Tips for Farmers Using Precast Concrete

Grain is only as valuable as the condition in which it is stored. Whether you’re storing barley, wheat, or maize, the right infrastructure makes all the difference between a profitable harvest and a costly loss.

We’ve helped hundreds of farmers across the UK upgrade their storage – and it often begins with a simple fix: selecting the right precast concrete walling system.

Here’s how to get it right.

01. Choose the Right Type of Walling for the Job

Grain exerts significant pressure on walls, especially when stored at height or agitated with stirrers. That’s why choosing the right system is the foundation of a long-lasting, safe grain store.

Use prestressed concrete panels for permanent perimeter walls

    • Designed for high-density storage with excellent load capacity
    • Can be slotted between steel posts or fixed to the face
    • Tongue-and-groove edges make sealing easy and keep the structure watertight

Go freestanding for movable dividers or overflow bays

    • Quick to install and reposition
    • Ideal for separating crops seasonally or adapting to changing volumes
    • Can be used internally alongside fixed perimeter walls

Cast-in systems for new builds or slab extensions

    • Reinforcement ties the panels into the slab for extra durability

    • Especially useful for large grain stores or new construction

    • Reduces point-loading on steel columns

02. Match Wall Heights and Load Capacity to Your Crops

Precast concrete makes it easy to size walls to your specific requirements. For grain stores, panels can be stacked to exceed heights of 6 metres, making them suitable for most grain stores.

    • Standard panel heights: 1.0m, 1.2m, 1.5m
    • Panel thicknesses: 150mm to 280mm, depending on grain height
    • Walls can safely retain grain above their top edge at its natural angle of repose
    • Lighter-weight walls (like freestanding units) are better suited to lower volumes or lightweight materials

03. Think About Grain Stirrers and Dryers

If you use stirrers or dryers, you’ll need walls that can withstand dynamic pressure and accommodate any necessary ductwork or cutouts.
    • Prestressed panels are ideal for this – stronger, thinner, and easier to adapt
    • Openings for dryer connections can be formed in advance or cut on-site
    • Internal movement and vibration won’t compromise the wall’s integrity

04. Use Precast Walls to Create Internal Bays

Splitting storage into bays helps you store multiple crops in the same shed without cross-contamination.

Options include:

We can also supply corner units and transition elements to suit your layout.

05. Seal Joints and Protect the Quality of Your Grain

Moisture is the enemy of stored grain. Even a small leak or damp joint can cause spoilage or infestation.

    • Use sealants like Sikaflex® PRO-3 to weatherproof panel joints
    • Check mastic joints annually and reapply if needed
    • Consider vapour barriers or ventilation systems for added protection

06. Build for the Long Term or the Next Season

One of the biggest benefits of precast concrete is flexibility. You can create a structure that lasts decades or one you can disassemble and reuse elsewhere.
    • Panels can be reused in different buildings
    • Freestanding and bolt-down units can be relocated
    • Modular design allows for phased construction or future expansion
