Interlocking Concrete Blocks for Fire Protection and Containment in Data Centres
A1 Fire-Rated Fire Protection Concrete Blocks Solutions for Data Centres
Elite Precast provides high-performance interlocking concrete blocks designed for fire protection and containment within data centres and critical infrastructure environments.
With increasing emphasis on Fire Protection Plans (FPP) and risk mitigation, the use of Class A1 fire-rated materials is essential. Elite Precast interlocking concrete blocks offer a non-combustible, robust and modular solution for creating fire-resistant enclosures, helping to contain incidents and protect critical infrastructure.
What Are Legato® Interlocking Concrete Blocks?
Fire Protection and Containment
Interlocking concrete blocks are used to construct fire-rated containment zones around high-risk infrastructure, forming a key part of a comprehensive Fire Protection Plan (FPP).
These systems provide robust, non-combustible barriers that help contain fire and limit its spread to surrounding areas.

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
They are particularly suited to:
Generator and fuel storage containment areas
Battery energy storage systems (BESS)
Transformer and switchgear enclosures
Electrical plant rooms and energy centres
Segregation of fire-risk zones within data centre sites
Benefits
Class A1 Fire-Rated Material – Concrete blocks are non-combustible (Class A1), making them ideal for fire protection applications and compliance with fire safety strategies.
Fire Containment and Risk Mitigation – Provides effective separation of high-risk assets, helping to limit fire spread and protect adjacent infrastructure.
Integral to Fire Protection Plans (FPP) – Supports compliance with site-specific fire safety requirements and risk management strategies.
Modular and Scalable Design – Interlocking blocks enable flexible layouts, allowing containment zones to be adapted as site needs evolve.
Rapid Installation – Dry-stacked systems allow for quick deployment, reducing construction time and enabling fast response to safety requirements.
Durable and Long-Term Performance – Precast concrete ensures long-lasting fire-resistant performance in demanding environments.
