Inflatable Flood Barriers

Protect Your Property From Flood Damage

When storms strike, speed matters. The Inflatable Flood Barrier from Garrison Flood Control provides a rapidly deployable flood defense system that can be set up in minutes — no tools, no sandbags, no hassle.

The Inflatable Flood Barrier forms a rigid, watertight, flood barrier for openings once inflated — providing solid, stable and reliable flood protection for homes, businesses, and critical infrastructure. Use The Inflatable Flood Barrier for doorways, windows, hallways, culverts, and anywhere that you need to hold back water.

The Inflatable Flood Barrier uses a high-tech “space fabric”, engineered to lock into place when inflated and pressurized. Specialized rubber gaskets around the perimeter seal against surfaces such concrete, asphalt, travertine or wood.

This effective and innovative flood barrier system offers flood mitigation and a protective flood-stop solution against severe weather, storm surges, flash floods, heavy rains, riverine flooding and more.

Engineered for Real-World Flood Conditions

The MAKO™ Inflatable Flood Barrier is designed to perform under pressure. Its unique structure locks into shape when inflated, allowing it to withstand the hydrostatic forces of rising water while sealing against uneven surfaces like concrete, asphalt, or gravel:

Inflatable Drop-Stitch Design: Creates a rigid, flat structure that maintains shape and resists deformation under pressure.

Lightweight & Portable: Units deflate and fold compactly for storage and transport.

Rapid Deployment: Flood barriers install in minutes with minimal labor—ideal for remergency response.

Reusable & Durable: Engineered for repeated long-term use, season after season.

Versatile Surface Seal: Works on concrete, pavement, or stone tiles with minimal ground prep.

What is Drop Stitch Fabric?

Drop stitch fabric is a space-age fabric designed in the 1960s for inflatable aircrafts. It needed to be incredibly durable under inflation and to be tear and cut resistant.

Thousands of small fiber strands connect the top layer and bottom layer, allowing the center to be inflated under pressure, while keeping the layers aligned and preventing panel deformation.

The material used in pressurized flood barriers is designed to resist punctures, while handling high pressures, debris impact and the hydrostatic and hydrodynamic forces expected in a flood.
