Reusable Aluminum Flood Barriers

TrapBag® Home Defense Aluminum Flood Barrier System

Engineered Protection for Garage Doors and Openings

When floodwater reaches your garage or storefront, protection must be structural.

The TrapBag® Aluminum Plank System is designed to protect doors, garages, loading docks, and other openings during storm surge or rising water events.

Unlike temporary surface barriers, this system is engineered for your exact opening and designed for repeated seasonal use.

Is This the Right Flood Barrier for Your Property?

This system is a strong fit if you:

  • Live near the coast or a surge-prone area
  • Experience repeated seasonal flooding
  • Want a reusable system for the same opening year after year
  • Prefer professional installation

It is designed for static flood conditions and must be installed on structurally sound surfaces.

If you need short-term, ground-level protection without permanent mounting, the Water-Filled Barrier may be a better choice.

How the Aluminum Plank System Works

The system includes permanently mounted vertical side channels and removable aluminum planks.

When a storm approaches:

  • 1 Slide planks into the side channels
  • 2 Stack them to the required height
  • 3 Engage compression seals between planks and channels

After the event, remove and store the planks for the next season.

Installation Overview

Each system is engineered for your opening before installation.

  • 1 Site Evaluation - Opening size, protection height, and structural conditions are reviewed.
  • 2 Frame Installation - Vertical side posts are anchored permanently to the structure.
  • 3 Seasonal Deployment - Before a storm, planks are inserted and stacked manually.
  • 4 Sealing Activation - Compression gaskets create a sealed barrier under static flood conditions.
  • 5 Post-Storm Removal - Planks are removed and stored for future use.

For residential and commercial properties, Emerald Green provides installation and seasonal service.

Why Choose an Engineered Opening System?

This system:

  • Protects the most vulnerable part of a structure
  • Is engineered per opening
  • Is reusable season after season
  • Requires minimal storage space
  • Can integrate with perimeter flood protection 

It is built for predictable deployment when storms return.

Performance Considerations

Each installation is engineered based on:

  • Required protection height
  • Opening width
  • Structural capacity
  • Hydrostatic load calculations 

The system is designed for static water conditions and must be installed properly to perform as intended.
