The Toblerone precast concrete systems can be used as obstruction to the passage of cars, truck, and other equipment. In the past, the barriers used to serve as an anti-tank obstacle. Now, the barriers are also used as counter-terrorism protection in public spaces, pedestrian precincts, airfields, bus stations and train stations. The barriers are put in place to simply prevent the crossing of vehicles over the private property or parking areas. As a rule, the barriers are laid in the locking arrangement and designed to resist an impact horizontal force of 100kN.
