HESCO Concertainer units have undergone an intensive series of laboratory and field tests and have been assessed by leading authorities in the US and worldwide.
Tests in the US include those undertaken as part of a research program into temporary flood-fighting structures. The research was conducted by the US Army Engineer Research and Development Center (ERDC). The resulting report concluded that HESCO Concertainer units had significant advantages over traditional sandbags, in terms of cost, time and labor requirement for installation, and outperformed alternative systems in many areas tested.
At the US Army Corp of Engineers (USACE) Flood-Testing Facility in Vicksburg, Mississippi, a HESCO Concertainer unit wall was constructed and filled with sand. The flood chamber was filled on the outer side of the structure with an increasing level of water, up to three-quarters of the units’ height; the units were then ‘overtopped’ with a wave simulator. Finally, the structure was hit with a 12-inch diameter log at 5mph, to simulate typical large debris found in flood water. Throughout all tests, the wall remained intact.
K12 is the certification of a structure against vehicle impact. A barrier is tested to demonstrate that it will stop a truck with a 15,000lb gross vehicular weight (GVW) traveling at a nominal 50mph. In 2004, a HESCO Concertainer barrier met the required standard; as a result, HESCO Concertainer was awarded K12 certification by the US Department of State. In 2005, a larger barrier met the requirements of the H50 standard, stopping a truck with a 65,000lb GVW traveling at 50mph. The trials were conducted by the Texas Transportation Institute.
