The HESCO MIL units must be unfolded and filled with gravel, sand, or soil, typically with a front end loader. With the exception of the fact that space must typically be left for the machinery used to fill the barrier, placing the barrier is normally quite similar to placing a sandbag barrier or an earth berm. The fundamental benefit of HESCO barriers is their quick and simple setup, which significantly increases its popularity with troops and flood fighters. Sandbag filling used to be a laborious process that took a worker roughly 20 hours to complete. Ten times as much work can be accomplished with HESCO barriers and a front end loader than with sandbags.
