Blast Resistant Walling

Blast-Resistant Precast Concrete Blocks for UK Data Centres

Proven Protection with Legato® and Vee® Blocks. Elite Precast Concrete’s Legato® and Vee® Blocks provide a robust, modular solution for blast protection and shielding in high-risk environments. Independently tested under high explosive conditions, these blocks are engineered to deliver maximum resilience, making them ideal for UK data centres, critical infrastructure projects, and defence and security applications.

Blast Walling Solutions for Critical Infrastructure

Blast-Resistant Performance
Rigorously tested under controlled high-explosive conditions. Independent trials confirmed both Legato® and Vee® Blocks deliver exceptional protective screening against blast events.

Fire Resistance
Certified Class A1 fire resistant in line with EN 13369 clause 4.3.4.4, ensuring reliable performance in both explosion and fire-related scenarios.

Modular and Flexible Design
Available in a variety of sizes, the interlocking design allows rapid construction of blast walls, perimeter barriers, and containment structures. Suitable for both temporary and permanent installations.

Long-Term Durability
Manufactured from high-strength precast concrete, offering resilience against environmental conditions, operational stresses, and long-term data centre security demands.

Data Centre Applications

Our precast concrete blast walling systems are trusted for a wide range of uses.

Data Centre Protection
Shielding power supply units, fuel stores, and other mission-critical assets from blast and fire risks.

Explosives Magazine Shielding
Creating protective enclosures for commercial and military-grade explosives.

Destructive Valve Testing
Providing safe containment during high-pressure destructive testing operations.

Protective Screening
Used for fireworks storage, explosive magazines, and sensitive defence materials.

Temporary or Permanent Blast Walls
Modular systems can be deployed rapidly for temporary protection or built as fixed, long-term installations.
