Benefits
Key Benefits
High Strength & Durability – Manufactured from high-quality precast concrete, Duo blocks are designed to resist contact from loading shovels, telehandlers and HGVs while maintaining structural integrity over time.
Fast and Flexible Installation – Bays can be assembled, extended, reconfigured, or relocated with ease, reducing downtime and allowing storage layouts to adapt to changing operational needs.
Excellent Load Retention – The mass and interlocking profile of Duo blocks ensure stable containment of loose materials such as salt, sand, gravel and aggregates.
Weather and Corrosion Resistance – Concrete construction offers excellent resistance to moisture, frost and corrosive materials such as road salt, helping to protect both the structure and stored materials.
Cost-Effective Solution – No fixing systems are required, keeping installation and long-term costs low.
Engineered for Your Environment
Design Versatility
Duo Interlocking Blocks can be stacked to varying heights and arranged in single, double, or multi-bay configurations. This allows operators to safely separate different materials while maximising available yard space. Bays can also be integrated with roofing systems where covered storage is required.
Quality You Can Trust
All Duo Interlocking Blocks from Elite Precast Concrete are manufactured in the UK under strict quality control procedures, ensuring consistent dimensions, reliable performance and long service life in demanding environments.
