What are bubble barriers?

Bubble Barriers & Bubble Tubing Technology

Originally developed during World War II to block submarine sound waves, Bubble Barriers and Bubble Tubing technology have since evolved into a versatile, eco-friendly solution for marine conservation.

Often referred to as air barriers, bubble curtains, or pneumatic barriers, this technology uses submerged perforated tubing, through which compressed air is released. The result is a rising wall of bubbles that forms a linear screen on the water’s surface, effectively containing or redirecting debris while oxygenating the water.

As awareness around marine conservation grows in New Zealand and globally, Bubble Barriers are gaining recognition as a cost-effective and energy-efficient solution for a range of marine applications. This technology has untapped potential for future innovations that could protect swimmers, aquatic wildlife, and entire ecosystems.
