A flood barrier system is an engineered assembly of aerospace-grade aluminum, stainless steel hardware, and compression gaskets, custom-fabricated for one specific opening. Sandbags leak, fail, and wash away. A Dam It Defense system deploys in about an hour and holds back up to 10 feet of water, storm after storm.

Common flood barrier system questions.
What is a flood barrier system?
An engineered assembly of aerospace-grade aluminum panels, stainless steel hardware, and compression gaskets, custom-fabricated for one specific opening. Measured to your property, rated to 10 feet of water, and built to redeploy season after season.
How much water can it hold back?
Up to 10 feet. Our aluminum is 2.5X the thickness of most competing products, rated to 40,000+ PSI, and the dual-phase EPDM gaskets strengthen as water pressure rises.
How long does deployment take?
About an hour. Engineered for fast, repeatable setup ahead of a storm watch. We also offer storage solutions when the system is not in use.
Do you build hurricane barriers specifically?
Yes. Every system is engineered for hurricane and storm surge conditions, rated to 40,000+ PSI, and designed to seal garage doors, entry doors, and sliders against surge pressure like Helene brought to St. Petersburg in 2024.
How is this different from sandbags?
Sandbags leak, fail, and wash away. A Dam It Defense system uses engineered aluminum and compression gaskets to create a watertight seal, deployed in about an hour and reused storm after storm.
Do you protect commercial properties?
Yes. We work with homes, commercial properties, HOA communities, Fortune 500 facilities, and municipalities. If it has an opening, we can engineer a system for it.
Where do you install?
St. Petersburg, Tampa Bay, Clearwater, Sarasota, Fort Myers, and the surrounding Gulf Coast. Our in-house team handles everything end to end.
