Hesco launches evolved barrier
Developed by military specialists and their civilian counterparts, the Terrablock barrier range is comprised of five designs, including low to high barriers for crowded public events and critical infrastructure.
The barriers are engineered to stop vehicle attacks and can incorporate anti-climb M50P1 crash rated barriers that are able to stop a 7.5 tonne truck travelling at 50mph.
Vehicle attacks present an increasingly dangerous phenomenon, as they provide an easily accessible delivery mechanism for explosives and afford protection to the handler.
The new systems feature a patented energy transfer system designed to protect critical infrastructure from vehicles, are crash rated to ASTM 2656- 15:M50P1 and have been tested against 10kg of high explosives whilst suffering only superficial damage.
While planning regulations and aesthetics within urban settings are resistant to structures that inhibit everyday operations, according to Hesco’s R&D team, the new barrier is designed to ‘blend into urban streetscapes’ and be rapidly deployed via a surface mounted unit.
Since its operational deployment during the 2012 London Olympics, five years of development have resulted in a distinctively designed system. Terrablock is built from flat packs, pinned together and applied with ballast, negating the requirement for foundations.
The system incorporates earth-filled vehicle barriers and climb resistant weldmesh panels, and the user has the ability to heighten its security level in response to changing threats.
Adam Wilding-Webb, Hesco's director of high security, stated that ‘the modular design of Terrablock provides the ability to easily and effectively upgrade site and event security in response to changing threat levels, whilst minimising the installation impact on the workforce and environment’.
The Terrablock barrier system has been installed to protect oil and gas infrastructure and public arenas, most recently the Royal Armouries Museum, Leeds.
