A Jersey barrier or Jersey wall is a modular concrete or plastic barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing the crossover case of a head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians during highway construction, as well as temporary and semi-permanent protections against landborne attack such as suicide vehicle bombs.
Road blockers provide a high level of security against unauthorised vehicle access. Designed to withstand substantial direct impact forces whilst avoiding the need for deep foundations, they are used to protect sites with shallow underground services from aggressive vehicle attack.
Enhanced Blast Wall Systems are extensively deployed with NATO, U.S. Military, UN and other military forces throughout the world. The conversion of traditional Sandbag walling concept into an enhanced Blast Wall System has helped to overcome problem of labour intensive and time consuming in a military environment that required mobility and rapid deployment.
