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

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

  • Stability

    ShoreJax 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

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