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.
24-Hour Visibility, All Weather Clarity
■ International Orange Buoys – Color resists fading and stands out in open water.
■ Marine Grade Reflectivity – SOLAS Certified retroreflective tape ensures night and low light visibility.
■ Integrated Lighting Options – Solar Powered LED Beacons with auto-on/off functionality and optimized flash patterns provide full time visibility day and night.
Tamper-Resistant Linkage System
■ 360 Degree Rotation – Each unit moves freely while maintaining interconnectivity.
■ High Strength – Linkages rated to 114,500 lbs. of pull strength.
■ Anti-Tamper Design – Secure Ball hitch mechanism with proprietary dual anti-access ring design.
■ Field Serviceable – Fully replaceable buoys on-site with no special equipment required.
■ Zero maintenance – Designed for a minimum 10-year maintenance free deployment.
