Concrete barrier blocks have many practical applications: - Anti-terrorist barriers to protect against terrorist attacks; - Protection of buildings and structures from collisions; - Security barriers during civil unrest. - Road dividers to safely separate pedestrians and vehicles; - Robust passive barriers to protect vulnerable access points at airports, train stations, hotels and tourist centers and prevent damage to vehicles. Temporary concrete barrier provides a quick and effective way to prevent access by unwanted vehicles. Blocks can be placed close together to form a long continuous barrier or placed individually. Barriers are most suitable where vehicle access prevention is required as they can withstand huge impacts. Blocks can be used to separate pedestrians and vehicles, keeping the site safe and quickly stopping oncoming traffic with a large mass of concrete.
