Doorway Flood Barrier
Protect building entrances from floodwater--installed only when needed.
Doorways are a common entry point for stormwater and flash floods. Our removable doorway flood barrier system uses fixed side channels and stackable panels to create reliable protection while keeping the entrance clear during daily operation.
Why Choose Our Doorway Barriers
Modular Protection Height
Add or remove panels as needed to match water level requirements
Fast Manual Deployment
Simple training required--install quickly when flood warning issued
Replaceable Sealing Gaskets
Improved sealing performance with easy-to-replace gaskets
Reusable & Easy to Store
Remove and store after the event--use again when needed
Aluminum or Stainless Steel
Choose the material that fits your project requirements
Clear During Daily Use
No obstruction to normal access when panels are removed
Common Doorway Flood Risks
Understanding the vulnerabilities at building entrances
Water Entry Under Doors
Water enters under doors and flows into lobbies, corridors, and basement levels causing extensive damage
Overwhelmed Drainage
Heavy rainfall overwhelms drainage systems near entrances, creating pooling water that seeks entry points
Uneven Thresholds & Frames
Uneven thresholds and out-of-square frames create leakage points that are difficult to seal with traditional methods
Slow Sandbag Deployment
Sandbags are slow to deploy, hard to seal effectively, and create disposal problems after the event
Stoplog-Style Removable Barrier
System Components
Side guide channels anchored to the walls
Stackable panels (stoplogs) to reach the required protection height
Top locking/clamping to secure panels and compress seals
Bottom + side gaskets (replaceable)
Optional base plate/threshold for uneven floors or worn thresholds
Also known as a stoplog flood barrier. This proven design provides reliable protection while maintaining normal access when not deployed.

Frequently Asked Questions
Will this block daily access?
No. Panels are removed and stored when not needed, leaving the doorway completely clear for normal daily access. Only the side channels remain fixed to the walls, which are typically flush-mounted and do not obstruct passage.
How do I choose the protection height?
Use your target water level or historic flood marks as a guide. We'll recommend the appropriate panel count and configuration after reviewing your site details. It's common to add 100-200mm safety margin above the expected water level.
Can it work with uneven thresholds?
Yes. Base plates/thresholds and leveling strategies can improve sealing on uneven floors. Floor photos help us advise quickly on the best approach for your specific situation. Custom base plates can be fabricated to match irregular floor profiles.
Do you provide drawings and installation guidance?
Yes. Share dimensions and photos and we'll provide detailed technical drawings, installation instructions, and guidance. Our drawings include mounting details, panel configurations, and recommended installation sequences.
How long does installation take?
Initial installation of the side channels typically takes 2-4 hours depending on wall material and opening size. Once installed, deploying the panels during a flood event takes only 10-15 minutes with basic training.
What maintenance is required?
Minimal maintenance is required. Clean the channels and panels periodically, inspect gaskets for wear, and replace gaskets as needed (typically every 3-5 years depending on use). Store panels in a dry location when not in use.
