Temporary Flood Barriers
Inflatable Water Dams for Fast Flood Protection
Temporary flood barriers provide fast, reliable flood protection for homes, businesses, and industrial sites. These inflatable water dams install 3 to 5 times faster than traditional flood barriers and can be reused 10 to 15 times. Simply unroll the barrier, fill with water, and create an instant flood defense.
Protecting your property from flooding has never been easier. Temporary flood barriers deploy with minimal manpower, eliminating the need for labor-intensive sandbags. Cleanup is simple, drain, roll up, and store for future use. Compact storage and portability make these barriers ideal for emergency flood response.

Durability and field repair
Temporary flood barriers are built from industrial-grade vinyl coated polyester, laminated with woven polyester for maximum durability. The white inner layer makes it easy to spot potential wear points. Barriers can be patched in the field; even in wet conditions, extending service life to 10–15 flood deployments or more.
Inflatable Water Dam Sizes
Inflatable water dams are available in sizes from 1 to 8 feet tall and 25 to 100 feet in length. Custom sizes are also available. Rental barriers are available, contact us for details.
Installing temporary flood barriers
Temporary flood barriers are easy to deploy:
- Unroll and unfold the inflatable water dam.
- Attach a garden hose to the fill port and fill with water until fully inflated.
- Overlap barriers as needed to create continuous protection. Overlapping creates a sealed joint for maximum water resistance.
Small barriers can be installed manually with 1-2 people. Larger barriers may require a track hoe or crane and a crew of 5. Example: 100 linear feet of flood barrier typically installs in under 2 hours (site conditions may vary). For additional information please refer to the Instruction Manual (pdf).
Common Installation Angles
Overlap Requirements
| Inflated Height | Standard Overlap Length | 90° Overlap |
|---|---|---|
| 2' | 3' | 4.5' |
| 3' | 4.5' | 6.75' |
| 4' | 6' | 9' |
| 5' | 7.5' | 11.25' |
| 6' | 9' | 13.5' |
| 7' | 10.5' | 15.75' |
| 8' | 12' | 18' |
How inflatable flood protection barriers work
Inflatable water dams feature an internal baffle system that stabilizes the barrier when filled. As floodwaters exert pressure, the baffles adjust and lock in place, preventing rolling and maintaining stability.
A minimum 25% freeboard is recommended (portion of barrier above water level). Additional freeboard may be required in moving water (3 ft/sec or greater) or on slick surfaces. For help sizing barriers and calculating freeboard, contact our team.

Why temporary flood barriers are better than sandbags
Sandbags require significant time, labor, and disposal effort. You need sand, bags, people to fill them, space to stack them, and post-flood cleanup. Sandbags can’t be reused and disposal may be regulated.
Temporary flood barriers eliminate this hassle. Simply roll out the barrier, fill with water, and you’re protected. After the flood event, drain and roll up the barrier for reuse. Faster, cleaner, and more cost-effective than sandbags.
Flood Barriers Frequently Asked Questions
The maximum water depth depends on barrier size and site conditions. Our largest barriers can typically hold water up to 6 feet deep, with 25% freeboard required for safe installation.
Any available water source can be used to fill the temporary flood barriers. Keep in mind that you’ll need an appropriate pump and hoses.
