Flood Protection Products

Removable flood barriers: which category fits which opening

All three categories are removable opening barriers: permanent hardware may stay on the building, and the barrier itself is deployed before water arrives and stored afterwards. The opening decides the category, not the product name.

• Garage openings: driveway slope, slab condition, span, and whether a center support is needed decide whether a garage barrier can seal. A garage door weather seal is not a flood barrier.
• Doorways: panel height comes from the threshold versus expected water at that door, and the side surfaces must support the selected system.
• Sliders and wide openings: stacked aluminum planks in side channels, with intermediate posts on wider spans, across the finished opening.
• Commercial entries, loading docks, and garages: see commercial flood protection.

Removable vs permanent: what to compare

Portable and permanent are installation categories, not guarantees of performance. Portable systems reduce permanent hardware but add storage, setup labor, site access before an event, and the risk of missed deployment steps. Fixed systems reduce setup steps but may need structural work, drainage changes, permits, inspection, and ongoing maintenance.

For each option, compare the same scope: the water path and openings addressed, documented product limits, deployment sequence and who is responsible, bypass paths and drainage, storage and maintenance, and the complete quoted scope rather than component-only pricing.
