Common options for Hostile Vehicle Mitigation

26th November 2015

Alongside their system of security fencing, gates and other installed barriers, many businesses and enterprises also require some form of Hostile Vehicle Mitigation (HVM) to stop vehicles from passing at certain times.

Whether designed to keep all vehicles out or just prevent access for unwanted ones, these systems come in a variety of structures and sizes. As founding members of the Perimeter Security Suppliers Association, we are well-placed to give you a breakdown of some of the most common options chosen.

1. Concrete barriers

Most people will have seen these lining the perimeters of motorways and dual carriageways, but they can also be used by businesses and event organisers to divert traffic towards designated entrances.

Each block is manufactured with a combination of high strength concrete and steel reinforcing, making them sturdy enough to remain standing or only move a short distance when hit at high speeds. Being very heavy, wide blocks, these are best suited to permanent tasks where there’ll not need to be moved regularly.

2. Sliding gates

Often used for utilities security, these installations are best placed on premises where highly important equipment or services are kept. This is due to the fact that such structures can easily be adapted with barbed wire, spikes and other additions if necessary, while also being slowly manoeuvrable whenever employees need to visit.

Designed to withstand the impact of a 7.5 tonne vehicle, such barriers are intended to defend against the highest level of threats, including attempts by criminals to gain entry to the site.

3. Mitigate barriers

A cheaper alternative to most other options, these smaller, maneuverable barriers are a more convenient option for sites which require regular access, often with multiple vehicles following each other at a time. The fact that they can be moved up and down quickly makes them ideal for motorway toll booths, entrances to low-security business premises and construction site security.

4. Bollards

Like mitigate barriers, these are designed purely to stop vehicles form passing, as pedestrians can easily get around them. When it comes to cars, vans and other vehicles, however, they are a very space-efficient structure, especially rising bollard systems which ascend from the ground when prompted by sensors or manual controls.
