Nuclear station with barriers

Nuclear Safety and Security Solutions

Nuclear sites and major construction projects present complex safety and security requirements, from managing vehicle and pedestrian movements during construction to protecting sensitive areas and critical infrastructure.

Our barrier systems can support edge protection, site segregation and traffic management, helping to protect pedestrians and workforces during construction and infrastructure works. Available as temporary and permanent solutions, our systems can support changing requirements across different areas and stages of a project.

We also provide Hostile Vehicle Mitigation (HVM), perimeter protection, concrete security barriers and access solutions for security-sensitive environments, helping to protect people, property and controlled areas from vehicle-related threats and unauthorised access.

Our products have been used on major UK nuclear projects and sites, including Hinkley Point C and Sellafield, supporting both construction activity and the protection of established nuclear infrastructure.

Multibloc

A vertical concrete barrier (TVCB) of 3 metres in length by 0.8 metres and weighing 2.5 tonnes, this product is used for workforce protection on roadways. Easy to install quickly on various surfaces, Multibloc is ideal for roads, construction sites, boundaries, vacant property and car parks. Multibloc is also available as a temporary TVCB solution, and has been used on schemes including the M6 J16-19 smart motorway and the M50 bridge repair.

Fleximax

Fleximax is an engineered Maxibloc (THVCB), designed to protect vulnerable areas in a wide range of industries such as construction, aviation and roads where a higher level of protection is needed. The barriers are also ideal for a range of street work that requires increased flexibility on angles of installation since the product can be positioned at angles of 74 degrees. Benefits & Features High level of protection Suitable for a range of applications Straight and angled solution

Bristorm Zero Fence

A non-tensioned wire-rope system impact tested to the very highest ASTM F2656 standard. The Bristorm Zero Fence is the most robust in the Bristorm portfolio achieving up to ZERO penetration and ZERO major debris. Tested to ASTM F2656 achieving M50 P1, it has become the industry’s leading high-security perimeter security fence due to its durability in extreme geographical locations. For lower-speed threats, see the Bristorm Beam Fence or explore our full range of permanent hostile vehicle mitigation.

Bristorm Bri-RISE Emergency Access Gate

Manually operated to eliminate the need for expensive hydraulics or to reduce the risk of electrical failure, these hostile vehicle mitigation gates are designed to offer access to authorised emergency vehicles only. Protect your site’s perimeter with the Bri-RISE Emergency Access Gate. Designed to integrate with the Bristorm Zero Fence, the Bri-RISE will complete any high-security perimeter line. The Bri-RISE has been impact-tested to both the international IWA 14-1 standard and the American ASTM F2656-15. Not only did the Bri-RISE Gate withstand a hit from a 7,200kg vehicle at 80km/h (50mph), but also achieved less than a metre penetration. The Bri-RISE has been designed with a self-balancing arm, meaning that it can be easily operated by a single user, while also reducing the risk of injury. A catch post can also be supplied to lock the gate arm into the open position when not in use. Further innovation has followed the initial development of the gate, the Bri-RISE can now be integrated into any existing or new fence lines. As well as this, the rising arm can be fixed in position allowing the arm to bridge a gap where underground services may be present. This reduces cost and eliminates the need to disrupt on-site operations. The steelwork on the gate has been hot-dip galvanised to BS EN ISO 1461 to give it added protection against corrosion and increase the longevity of the gate. We can also provide thicker coating and powder coating on client request.

HVM 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 on-site 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

Bristorm Impeder Bollards 50HD

The most heavy-duty option in the Impeder range, the Impeder 50HD has been designed to protect against high-velocity attacks from large vehicles. Strong and imposing, the Impeder Bollard 50HD is the heaviest duty option in the Impeder range, capable of withstanding a 7,500kg vehicle at 80km/h (50mph).

Bristorm Impeder Bollards – Shallow Mounts

The Bristorm Impeder Shallow Mount range of HVM bollards are made up of standard CHS sections, cast-in concrete or socketed. View our Bristorm Impeder Bollards – Standard Foundation →

Bristorm Impeder Bollards – Standard Foundation

Need permanent HVM without restricting pedestrian access? Impeder Standard Bollards are the ideal solution. From low impact protection to high-security hostile vehicle mitigation (HVM), the Bristorm bollards can be installed across all urban and industrial sectors keeping critical infrastructure, assets and people safe. They are tested at speeds between 30 and 50mph. View our Bristorm Impeder Bollards – Shallow Foundation →

REBLOC

REBLOC is a precast concrete vehicle restraint system designed to provide protection on high speed roads. There is a wide range of REBLOC products designed to suit all locations and applications ranging from normal to very high containment and low working widths. The individual elements form a high strength continuous chain that safely absorbs energy and impact forces. Technically advanced, all REBLOC safety barriers are tested to EN 1317 to ensure suitability and performance for road projects. With key safety features and benefits, as well as versatility, REBLOC is an outstanding choice for any highways related scheme. What Is REBLOC? Barriers with a minimum design life of 50 years are mandated for permanent use in England on central reserves of roads with high traffic volumes. The REBLOC concrete vehicle restraint systems (VRS) are precast products that allow for rapid deployment across the strategic road network. The off-site manufacture also eliminates wet trades on-site, reduces the risk to the workforce with shortened installation times and is immediately operational with no curing time required. Ranging from normal containment to very high containment, our full suite of both permanent and temporary concrete VRS are tested to EN 1317 and are CE marked. Our precast systems are the product of choice for main contractors as the requirement for off-site manufacture increases. See REBLOC in action on the M5 central reserve upgrade and M74 bridge pier protection. View Our REBLOC Brochure
