Portable Flood Barriers
Reusable, Scalable Flood Protection. No Sandbags Necessary.
When waters are rising, every second counts. As a portable flood barrier, the NOAQ Boxwall is designed for fast deployment, strong protection, and reliable performance to keep water away from infrastructure, homes, and people.
How it Works
Hold Back the Flood With the NOAQ Boxwall
The NOAQ Boxwall is a modular flood barrier that is reusable and easy to deploy at scale to protect infrastructure, property, and lives.
Each section connects without tools and includes a seal on the underside that uses the weight of the water against it to secure the barrier to the ground. As the water rises, the seal tightens.
The panels weigh only 33 pounds per piece, which is 1% of the weight of an equivalent sandbag wall. They can also hold back floodwaters that are 40 inches deep. Emergency crews can build hundreds of feet of protection in a matter of hours, compared to the days of round-the-clock work required for a sandbag wall with similar stability.
Rapid Setup
100% faster than traditional sandbags (based on two people setting up 660 linear feet).
Free-Standing
Free-standing barriers become more stable as floodwaters rise.
Versatile and Reusable
Modular design adapts to curves, corners, and tight spaces. Plus, it's reusable.
Proven
NOAQ flood barriers have been protecting homes, businesses, and infrastructure for 30+ years.
