Blastproof and crashproof, KarabloK is being marketed as an anti-terrorist barrier made out of precast concrete. The modular, precast concrete system can be quickly assembled to form a durable, effective, and visually appealing security barrier. The system is made of large transportable concrete units that can be positioned either permanently or temporarily without any foundations or ground-fixing required. Typically, operators can expect to install about 110 yards per day with cranes and trucks. Each KarabloK is 4 feet high and walls can be built up to at least 20 feet high with multiple units. Each unit is 47 inches tall, 83 inches long, 55 inches wide, and made from 7.9-inch precast concrete. Two 32-mm jointing rebars lock two units together through the system’s internal reinforcement cage. The nut, washer, and bung arrangement provides the barrier with some flexibility, which enables it to withstand large blast and impact forces. For more information, visit www.karablok.global.
