ShoreJax™ are flexible interlocking concrete armor units available in a variety of sizes, used to resist the erosive forces generated due to high velocity water.

ShoreJax™ can be placed in random configurations (such as those required to line underwater scour holes) or in a uniform pattern. The voids in the system are able to be filled with desired soils and vegetation to provide an aesthetically pleasing result.


  • Energy Dissipation

  • Stream Bank Protection

  • Bridge Pier Scour Protection

  • Toe Stabilization

  • Drop Structures

  • Wiers

  • Velocity Reduction at Pipe Outfalls

  • Habitat Development

  • Water Flow Control

  • Durability

    ShoreJaxTM will not suffer loss of function due to chemical degradation, UV degradation, biological degradation, vandalism or aging throughout its design life.

  • Stability

    ShoreJaxTM has the necessary strength characteristics to resist displacement due to imposed tractive forces and wave loads, including the necessary strength to resist both lateral displacement and vertical uplift.

  • Acceptability

    ShoreJaxTM becomes part of the landscape and the local ecosystem. Its construction is free of hazardous projections – thus offering opportunities for recreation – as native grasses are quick to germinate in the soil-filled cells.

  • Affordability

    The ShoreJaxTM System is engineered to ensure comprehensive project design and high quality components at 20-50% lower than alternative erosion control methods.
