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
-
- 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:
- Freestanding walls – quick to move or reposition
- Bolt-down walls – more secure but still modular
- Panels in posts – semi-permanent and easy to expand
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
-
- Panels can be reused in different buildings
- Freestanding and bolt-down units can be relocated
- Modular design allows for phased construction or future expansion
