Applications of Interlocking blocks
Elite Precast Concrete interlocking blocks are suitable for a wide variety of commercial, industrial and infrastructure applications, including:
Electric Vehicle Containment Areas — Used to safely isolate damaged EVs where there is a risk of thermal runaway or fire, supporting site safety and fire protection planning.
Emergency Shelters — Rapidly deployable structures for protecting high-value assets, machinery or critical equipment.
Fire Protection and Fire Breaks — Concrete’s inherent fire resistance makes interlocking blocks ideal for fire containment zones, fire breaks and use within a Fire Protection Plan (FPP).
Flood Defence and Flood Protection — Suitable for temporary or semi-permanent flood barriers, providing effective protection for people, property and infrastructure.
Freestanding Walls and Barriers — Ideal for traffic segregation, security perimeters, flood barriers and site management.
Retaining Walls — Effective for managing changes in ground level, landslip risk, or material retention, subject to appropriate engineering checks.
Security Solutions — Used to restrict unauthorised vehicle access and enhance site security.
Storage Bays — Commonly used to construct bays for grain, grit, sand, salt, scrap metal, waste and recycling materials.
Compliance & Technical Support
All Elite Precast Concrete interlocking blocks are engineered to meet BS EN standards and achieve Class A1 fire classification under EN 13501-1 — meaning they are non-combustible, will not burn, crack or emit toxic fumes, and are suitable for inclusion in Fire Protection Plans.
External storage bays and walls constructed using interlocking concrete blocks are typically considered temporary structures. In many cases this means planning permission is not required, as the blocks can be dismantled and relocated with ease — though we always recommend confirming requirements with your local authority. Temporary structures can also result in lower or zero business rates and are generally more cost-effective to build than permanent alternatives.
Elite Precast Concrete always recommends that all wall designs and configurations are checked and approved by a qualified structural engineer to ensure suitability for the intended application, loading conditions and site environment.
We provide full technical and product support, including CAD drawings, technical data sheets and compliance and certification documentation to assist engineers, designers and estimators during project planning.
