Fire-Resistant Partition and Perimeter Walls
Elite Precast Concrete's Duo™ interlocking concrete blocks provide a robust, non-combustible and flexible solution for constructing fire-resistant partition and perimeter walls.
Designed to deliver high mass, stability, and proven fire performance, Duo™ blocks are widely used across industrial, waste, recycling, agricultural and commercial sites where fire separation and site safety are critical.
As the sole UK manufacturer of Duo™ interlocking blocks, Elite Precast Concrete supplies a trusted precast system that combines fire resistance with rapid installation and long-term reusability.
What Are Duo™ Interlocking Concrete Blocks?
Designed for Fire Safety and Site Protection
Fire-resistant partition and perimeter walls play a vital role in reducing fire spread, segregating high-risk materials, and protecting people, property and operations.
Duo™ interlocking concrete blocks are manufactured from high-quality precast concrete, offering non-combustible performance and excellent resistance to heat, impact and environmental exposure.
The dry-laid, interlocking design allows walls to be constructed without mortar or permanent foundations, making Duo™ blocks ideal for temporary, semi-permanent, or relocatable fire separation structures.
Why Choose Elite Precast
With decades of precast expertise, in-house engineering support and a proven delivery record on projects of every scale, Elite Precast is the partner specifiers trust. We pair robust, repeatable manufacturing with the flexibility to engineer bespoke solutions when a standard product will not do.
Key Applications
Duo™ interlocking concrete blocks are commonly used to form fire-resistant walls for:
Waste and recycling facilities
RDF and combustible material storage areas
Biomass, woodchip, and composting sites
Industrial yards and warehouses
Agricultural storage compounds
Firebreak walls and site perimeter separation
Temporary fire partitions during site reconfiguration
Benefits
Key Benefits of Duo™ Fire-Resistant Walls
Non-Combustible Concrete Construction – Provides inherent fire resistance suitable for high-risk environments such as waste, recycling and biomass sites.
High Mass and Structural Stability – The weight and interlocking profile of Duo™ blocks help resist collapse and maintain wall integrity during fire exposure.
Rapid Installation with Minimal Disruption – Walls can be installed quickly using standard lifting equipment, with no curing time required.
Modular and Reconfigurable – Partition and perimeter layouts can be altered or extended as site requirements change.
Durable in Harsh Environments – Excellent resistance to impact, abrasion, weathering and repeated mechanical handling.
Temporary Structures with Fire Safety and Commercial Benefits
Fire-resistant walls constructed using Duo™ blocks are typically classed as temporary or semi-permanent structures. As a dry-laid and reusable system:
Planning permission may not be required (subject to local authority approval)
Walls can be dismantled or relocated as fire risk zones change
Reduced installation costs compared to in-situ concrete walls
Long-term value through reuse across multiple sites or projects
Engineered for Your Environment
Design Flexibility and Wall Configuration
Duo™ blocks can be configured to create straight, stepped, or cornered partition and perimeter walls. Wall height and layout are influenced by:
Fire strategy and separation requirements
Stored material type and risk profile
Block size and stacking arrangement
Ground bearing capacity
Wind loading for exposed or freestanding perimeter walls
Elite Precast Concrete provides stability and loading guidance to support safe and compliant wall design.
Durability, Fire Performance and Finish
Manufactured from high-quality precast concrete, Duo™ blocks offer:
Excellent fire resistance due to non-combustible material properties
Resistance to impact, abrasion, and freeze–thaw conditions
Concrete finish classified as basic in accordance with the National Structural Concrete Specification
Duo™ interlocking concrete blocks are manufactured in compliance with BS EN 1992-1-1:2004 – Design of Concrete Structures.
Safety and Installation Considerations
Walls must be constructed on a firm, level surface with adequate bearing capacity
Fire strategy, wall height, and layout should be reviewed as part of site risk assessments
Wind loading must be considered for freestanding or perimeter walls
Blocks should be inspected prior to lifting and reuse
It is the customer's responsibility to ensure appropriate structural, fire, and site safety checks are completed prior to installation.
