HVM Wall Systems

Permanent Hostile Vehicle Mitigation Wall Systems

Superior wall system developed to provide protection against VBIED attack and unauthorised access.

This permanent system features fixed walls with pre-fabricated, rapid-install mini-pile foundations. It uses proprietary construction materials, combining two steel plates connected by traverse bars, filled with ready-mix concrete, offering exceptional protection against vehicle impacts and blasts.

Various wall configurations are available, from standard blast walls to advanced solutions for high-security sites. All systems are tested to BSI PAS 68 standards and suitable for city centres, transport hubs, industrial facilities, and government or defence sites.

Key features:
  • PAS 68 certified – Protection against VBIED attacks, unauthorised access, and blasts
  • Customisable aesthetics – Paint, brick/stone cladding, granite, or cement rendering to blend with surroundings
  • Impact and blast mitigation – Prevents dangerous secondary projectiles 
  • Modular construction – Speeds up onsite installation 
  • Compact design – High strength with a smaller footprint than reinforced concrete
  • Rapid-install foundations – Minimal excavation reduces utility diversion and saves time
  • Bristorm wall systems are tailored to meet project needs and a variety of explosive and HVM threat levels
