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.

Tapered Block Details

ArmorFlex and A-Jacks for Pier Scour Protection

ArmorFlex and A-Jacks are accepted pier scour countermeasures according to Federal Highway Administration (FHWA) guidelines. These highly engineered systems provide a maximum factor of safety to critical structures.

Armortec Solutions for Shoreline and Stream Bank Protection

The A-Jacks, ArmorFlex, and ArmorLoc systems offer permanent solutions to streambank erosion by armoring the area of maximum scour. These systems also promote native vegetation for a natural enhancement.

ArmorFlex and ArmorLoc for Heavy Loading Applications

ArmorFlex and ArmorLoc provide a speedy and more flexible alternative to a traditional concrete pad and can be used for tank / heavy equipment turning pad.

A-Jacks and ArmorFlex for Channel Drop Structures

Our Erosion Control Blankets and Turf Reinforcement Mats offer cost-effective alternatives to dumped stone for feeder channels and diversion ditches. Installation is fast, easy and does not require any heavy equipment - resulting in a savings of both production time and project costs.

ArmorFlex for Channel, Spillway and Dam Overtopping Protection

Armorflex Tapered Block Series is capable of providing erosion protection in high velocity applications, such as spillways, overtopping and diversion channels. As a cost effective alternative to reinforced concrete lining or grouted rip rap, the Armorflex Tapered Series provides needed protection while fulfilling environmental quality requirements including vegetation promotion, habitat enhancement and associated water quality benefits.

ArmorFlex and ArmorLoc for Outfall Protection

The unique shape and interlocking design of ArmorFlex cabled systems and ArmorLoc hand placed systems provide permanent erosion protection at culvert outfall locations. Unlike dumped stone, which typically requires maintenance and replenishment after periodic events, ArmorFlex and ArmorLoc systems are permanent solutions that dramatically reduce life-cycle costs.
