Blast and Impact Protection Walls
Engineered Protection. Proven Strength. Modular Confidence.
Elite Precast provides blast-resistant and impact protection wall systems using Legato® interlocking concrete blocks, engineered to deliver exceptional strength, stability and rapid deployment for high-risk environments.
Manufactured from high strength 50N/mm² concrete, Legato® blocks offer a robust, modular solution for blast mitigation, vehicle impact protection and asset shielding, without the need for mortar, steel reinforcement or permanent foundations.
What Are Legato® Interlocking Concrete Blocks?
What are Blast and Impact Protection Walls?
Blast and impact protection walls are designed to absorb, deflect and contain high-energy forces caused by explosions, vehicle strikes, plant movement or accidental impacts. Legato® interlocking concrete blocks form heavy-duty, gravity-based structures that rely on mass, interlock and geometry rather than mechanical fixings.
This makes them ideal for temporary, semi-permanent or permanent protection in industrial, infrastructure and security-critical environments.
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 Benefits for Blast and Impact Protection Projects
Modular and Scalable – Walls can be built to varying heights and thicknesses to suit specific risk profiles and site constraints.
Temporary or Permanent Solutions – Legato® walls are often classed as temporary structures, reducing planning requirements and allowing future relocation.
Cost-Effective Protection
No foundations typically required (subject to ground conditions)
Faster installation than in-situ concrete
Reduced labour and downtime
Environmentally Responsible
Manufactured from 100% natural materials
Locally sourced aggregates
Fully recyclable at end of life
120-year design life supports sustainability targets
Engineered for Your Environment
Design, Stability and Loadings
Blast and impact protection walls must be designed for site-specific risks, including:
Expected impact loads
Blast overpressure
Wall height and configuration
Ground bearing capacity
Wind loading for free-standing walls
Elite Precast provides access to its Stability and Loadings information, offering guidance on wall geometry, block selection and ground conditions.
⚠️ Important: All blast and impact protection walls must be reviewed by a qualified structural engineer prior to installation.
Safety and Installation Considerations
Ensure walls are constructed on a suitable, level base
Avoid direct repeated impact where possible
Inspect lifting pins and blocks prior to installation
Consider strapping top layers where impact risk is elevated
Wind loading should be assessed for walls above 4.8m
