The Subsurface Dune Restoration System (SDRS™) makes use of large sand-filled geotextile containers which become somewhat fluid and flexible during wave run-up on a surface being protected providing a soft revetment. A fluid transfer system is operable to both fill the containers and support them in an installed position. The containers are effective to dissipate wave action and aid natural accretion by slowing water velocity while not providing a rigid or hard revetment. The reduction of the wave force and water velocity and the soft revetment surfaces are the result of use of container materials having predetermined permeability and weather resistant characteristics. The permeability is limited to ranges permitting seepage of water while retaining the sand within the containers.

SDRS™ Features:

• Unlimited vertical window of protection
  
• Gentle 3:1 slope based on design
  
• Stepped shape reduces wave run-up and scour
  
• Natural sand recovery (long term cost savings)
  
• Unlimited pedestrian access / egress
  
• Viable turtle nesting habitat (increased elevations)
  
• ProTecCell™ containers (tear drop shaped)
  
• Welded seams (heat sealing fabrication process)
  
• ProTecShield™ protective outer shroud
• Internal strap restraint system (not exposed)
• Fluid transfer system (internal filling manifold)
