Designed for Performance. Proven on the Water.

The Gibraltar Waterborne Barrier is a next-generation floating security solution designed to stop unauthorized watercraft, deter breach attempts, and maintain long-term integrity in the harshest marine environments. Gibraltar’s barriers are trusted by federal agencies and critical infrastructure operators and this barrier delivers unmatched strength, durability, and visibility – day or night, season after season. The Gibraltar Waterborne Barrier can be utilized to help secure harbors, ports, naval bases and international borders.

Rugged, Solid-Core Construction

  • No Hollow Chambers – Solid design throughout to prevent failure from puncture or flooding.
  • Three Standard Sizes – 4 ft., 5 ft., and 6 ft., diameters.
  • Buoyancy Assurance – Maintains 75% or more of floatation above the waterline.
  • Durability Built-In – Impact, chemical, and UV resistant inhibitors for 20 years of service.
  • Galvanized Steel – All fabricated components hot-dip galvanized to ASTM A123 and paired with stainless steel fasteners.
  • Temperature Stable – Can handle fluctuations across extreme temperature ranges.
  • Anti-Climb Design – Smooth outer contours offer no grip points. This along with 360-degree rotation make the barrier extremely difficult to scale or perch on.
