ArmorFlex is a flexible, interlocking matrix of cellular concrete blocks of uniform size, shape, and weight used for hard armor erosion control. ArmorFlex blocks have specific tested hydraulic capacities and are laced longitudinally with revetment cables to provide ease-of-handling and rapid installation.

Research Proven Erosion Control Performance

ArmorFlex revetment systems combine the favorable aspects of lightweight blankets and meshes such as porosity, flexibility, vegetation encouragement and habitat enhancement with non-erodible self-weight and the high tractive force resistance of a rigid lining.

ArmorFlex has proven to be an aesthetic and functional alternative to dumped stone riprap, gabions, structural concrete and other heavy-duty, durable erosion protection systems.

Benefits of the ArmorFlex System:

  • Engineered block system supported by extensive full-scale testing – this verified performance means long-term performance without costly maintenance.
  • 20% open area – Allows full vegetation for the entire system to meet regulation demands and provide an aesthetic solution.
  • Fast and low cost installation – Substantial savings on large projects when compared to large diameter riprap.
