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.
