Road Defense Barriers

Defence-Structures DEAD STOP BARRIERS are designed to resist the impact from moving vehicles, and to stop them in a short distance without the truck or the pay load entering your secure area. They can be built to resist a variety of threats depending on the likely speed of approaching vehicles. They can defend against, for example: a 7.5 tonne at 30km/hr, (equal to a 5 tonne truck at 36km/hr, or a 1.5 tonne car at 70km/hr); or a 7.5 tonne truck at 80km/hr, (equal to a 40 tonne truck at 35km/hr or a car at 180km/hr !) . And of course there are heavier barriers available that will stop the 7.5 tonne truck at 50km/hour, or 80km/hour.

They are designed to stop the truck dead in 2m, and to prevent penetration of the protected area. The 2m is the crushing of the truck, not the barrier.

They can have chains or handrails connecting them to stop motorcycles or shopping trolleys. They should be combined with gates, labyrinths, cover from view screens and other defence structures. Keeping potential bombs as far away as possible from the vital areas is an important factor in force protection.

Such road barriers may be accompanied by softer barriers to make them less lethal.

The barriers may be founded in holes filled with concrete, or can be surface mounted on concrete plinths; you will need to describe the emplacement to us before design.

Similar barriers can be built to withstand bigger vehicles at any speed, but it will usually be better to limit approach speeds if possible.

Depending on their positioning they can also be suitable car bomb protection structures.

DEFENCE STRUCTURES CONCRETE ROAD DRAGON'S TEETH: There is also a need for temporary road barriers, and barriers that do not need to have foundations. In this case the barriers are a battery of DEFENCE-STRUCTURES Dragon's Teeth. These are specially shaped triangular concrete blocks that can be lifted into position fusing a fork lift truck or crane and linked with chain to block roads or other possible approaches. The kit for these consists of sets of reusable formwork with sets of internal steel work, into which the client can pour concrete, either at a distance or on the final resting site. These road Dragon Teeth can also be fitted with personnel access points and vehicle gates. Precast dragons teeth are quick to install and remove.
