The Preferred Sequence of Installing Flood Gates: Why Flood Gates Should Follow Roller Shutters

In flood-prone areas, protecting your property requires a strategic approach to safeguard against both rain and floodwaters. One effective method is to install flood gates in conjunction with roller shutters. This dual-layer protection system ensures comprehensive defense against water ingress. Here’s why the preferred sequence is to install flood gates after roller shutters and how this setup provides optimal protection.

The Role of Roller Shutters

Roller shutters serve as the first line of defense against rain and other external elements. Their primary functions include:

• Preventing Rain Splash: When closed, roller shutters block rain from splashing into the room, keeping the interior dry.
• Providing Security: Roller shutters offer additional security by preventing unauthorized access and protecting against debris.
• Safeguarding from Theft: Roller shutters can be closed to prevent theft during flood events, adding an extra layer of security for the property.

The Function of Flood Gates

Flood gates are specifically designed to stop floodwaters from entering a property. Their key benefits include:

• Blocking Water Ingress: Flood gates provide a strong barrier that prevents floodwaters from entering the premises, protecting the interior and valuable assets.
• Withstanding Mechanical Forces: Built to endure the pressure of floodwaters and debris, flood gates offer robust protection.
• Durability and Longevity: Constructed from high-quality materials, flood gates are designed to last for decades, providing long-term flood protection.

Preferred Installation Sequence: Flood Gate First, Then Roller Shutter

The preferred sequence of installing flood gates after roller shutters maximizes the effectiveness of both systems. Here’s why this approach works best:

1. Primary Flood Defense: The flood gate is deployed first to block any potential floodwaters from entering the premises. This initial barrier is crucial for preventing water ingress and protecting the property.
2. Rain and Security Defense: After deploying the flood gate, the roller shutter is then closed. This secondary barrier prevents rain from splashing into the room and provides additional security against unauthorized access and debris.
3. Protecting Mechanisms and Assets: In a multilayer carpark, for example, this setup is crucial. The flood gate ensures that customer cars and other valuable assets remain dry and safe from floodwaters, while the roller shutter protects the motorized mechanism from rain damage and theft.
4. Enhanced Structural Integrity: Installing the flood gate first provides a robust base, making it easier to secure the roller shutter in place. This sequence ensures that the entire system can withstand higher water pressures and debris impact.

Example: Multilayer Carpark Protection

Consider a multilayer carpark where both motorized mechanisms and customer cars need protection. The installation sequence of flood gates followed by roller shutters offers a layered defense:

• Step 1: Deploy the Flood Gate: The flood gate is quickly deployed to prevent floodwaters from entering the carpark, providing an initial layer of protection.
• Step 2: Close the Roller Shutter: The roller shutter is then lowered to prevent rain from splashing into the carpark, keeping the area dry and protecting the motorized mechanisms from theft and debris.
• Result: Comprehensive Protection: This dual-layer system ensures that both the mechanisms and the customer cars are shielded from rain and flood damage, maintaining the integrity and functionality of the carpark.

Conclusion

The strategic installation of flood gates after roller shutters offers a robust and comprehensive defense against both rain and floodwaters. By first deploying the flood gate to block floodwater ingress and then closing the roller shutter to prevent rain splash and provide security, property owners can ensure maximum protection for their assets and infrastructure. This approach is particularly effective in environments like multilayer carparks, where protecting motorized mechanisms and valuable assets is critical. Implementing this preferred sequence provides peace of mind and long-term security against the damaging effects of floods.
