In deploying defensive structures for applications like flood control and homeland security, speed and efficiency are of paramount importance. That’s where Hesco Concertainer units come into their own. They are easy to load, transport, unload and install. Neither specialized equipment nor trained labor is needed during installation. The benefits are clear: unlike sandbags, Concertainer units can be filled and stacked by a couple of people using a bucket loader, and unlike sandbags, they can be stacked and joined together easily. A typical wall of Concertainer units, equivalent to 1500 sandbags, can be erected and installed by two men using a standard front loader in 20 minutes. A similar wall made with sandbags would take ten men around seven hours to build. Walls and protective barricades can be built very quickly, with little need for complex job planning or deliveries of secondary materials. The system is ideal for the widest range of civil and military engineering installations, yet its use is cost effective, practical and highly efficient. Seven hours and ten men, or 20 minutes and two men? The answer is clear.
