AET Flood Defence – Aqua-Sac and Alteau Flood Barrier

AET Flood Defence – Aqua-Sac® & Alteau Mobile Flood Barrier

At AET Flood Defence Limited, our mission is to revolutionise the approach to rapid flood defence deployment across the UK. By combining two innovative solutions – the Aqua-Sac® and the Alteau Mobile Flood Barrier – we offer effective, efficient, and reliable flood protection for homes, businesses, and infrastructure.

Aqua-Sac® Self-Inflating Sandbags

The Aqua-Sac® is a UK-patented, self-inflating sandbag that offers a practical and sustainable alternative to traditional sandbags. Featuring our unique central stitch design, the Aqua-Sac® expands when submerged in water, absorbing up to 13 litres in just five minutes.

  • Composed of a durable jute outer sack and a non-woven inner bag, with our patented centre stitch.
  • Contains a super-absorbent polymer that activates on contact with water.
  • Lightweight and compact when dry – easy to store and transport.
  • Transforms into a robust flood defence unit in minutes.
  • Proven and trusted in emergency flood scenarios.

Ideal for domestic, commercial, and local authority use, the Aqua-Sac® offers a fast-deploying, cost-effective flood protection solution.

Alteau Mobile Flood Barrier

The Alteau Flood Barrier is a cutting-edge, self-rising barrier designed for rapid deployment without the need for external power or pre-inflation. Developed over two years and now in its third generation, this highly portable solution uses the very force of the incoming water to activate and rise into place.

  • Made from heavy-duty 610g and 450g polyethylene fabric.
  • Deploys automatically with water pressure, rising up to 1 metre in height.
  • Can extend for several hundred metres, suitable for large-scale protection.
  • Quick and easy setup – install in minutes with just two people.
  • Compact, reusable, and easy to clean and store.

The Alteau Barrier is favoured by emergency response teams and is perfect for:

  • Temporary flood defence
  • Creating water reservoirs
  • Stream diversion and damming
  • Containing chemical spills

The system is modular – multiple units can be joined via a secure Velcro fastening system. 90-degree corner units allow for flexible layouts around buildings or critical infrastructure.

Whether you need a rapid-response solution or long-term flood defence, AET Flood Defence products deliver peace of mind and proven performance.
