Rock riprap was considered but the closest source was more than 60 miles away. ARMORMAX® was selected because it costs significantly less to ship, while outperforming hard armoring solutions. One truckload of 20,000 square yards of ARMORMAX® is equivalent to 667 truckloads (6,667 cubic yards) of rock riprap. Not only does this cut transportation costs, but it minimizes the project's overall carbon footprint by reducing transportation emissions. And, because ARMORMAX® is a vegetating system, it provides valuable pollutant removal capabilities.
