What do flood barriers do?

Flood barriers act as flood control devices to protect your property, reducing your clean up, damage and insurance claims. The barriers are demountable, which means they are stored away in normal conditions and only deployed in a flood warning. A flood gate is another name for a flood barrier.  A flood event leads to complete upheval of your life, and usually means moving out of the property for several months while the clean up and repair is complete. Flood barriers protect against water entering into your property or land, significantly reducing the ingress of water, which will reduce the amount of clean up required after the flood water as disspated, reducing the impact or disruption of the flood on your home or business.

What are flood barries made of?

Flood barriers can be made of aluminium or composite material. The size of the barrier will determine the material you will need. Aluminium flood barriers barriers can be manufactured to any width with the use of demountable aluminium posts, where as composite barriers are limited to 1m or 1.5m openings.

Flood barriers are robust and reliable flood mitigation product to protect your business and home from flooding. Here is a break down in the advantages and disadvantages of installing flood barriers on you property.

Benefit of Flood Barriers

  • Bespoke length – Buffalo Flood Barriers offer flexibility because they can be designed and manufactured to any length. The flood barrier can be installed on a single door or joined together to create a flood wall or used to create a bund/compound around a key asset. This flexibility allows for solutions to be tailored to your requirements and makes flood barriers a popular solution for commercial and residential buildings. This also means your barrier is always manufactured bespoke to your property. It also means flood barriers can be designed for driveways, doors or loading bays.
  • Multiple height options – the Buffalo Flood Barrier can be manufactured in 200mm or 400mm increments height up to a height of 2000mm, making it applicable to a wide range of flood risks.
  • Demountable – the Buffalo Flood Barrier can be erected only when a flood risk is imminent. The barrier system takes minutes to deploy, therefore it is a flood barrier for garages or loading bays where vehicles are crossing each day.
  • Bund/Compound – the flood barrier can also be used to create a compound around a key asset or building, which can be erected on a semi permanent basis. Flood gates can be built into a flood wall or compound to offer pedestrian access, reducing the need to disengage the flood wall.
  • Simple but effective – flood barriers are a proven way to protect your business and home from flood risks.
  • Less moveable parts mean they are more effective than doors. Water will find the weakest point to enter the property, and hinges on doors can provide an issue. In contrast, flood barriers have very few moving parts. They are also rarely used and therefore kept in good condition. This means they are likley to be more effective than flood doors.
  • Flood barriers are easier to maintain than flood doors. If the seal on a flood door is damaged, then there is no alternative but replacing a new door. However, if the seal on a flood barrier is damaged a replacement seal can be shipped out the next day.

Disadvantage of Flood Barriers 

  • Human intervention – flood barriers do not offer passive protection, and instead require a humans to deploy the system. This can lead to errors and requires people to present when a flood risk is imminent.
  • Storage – as flood barriers are unlikely to be deployed all the time, particularly if vehicle access is required on a daily basis, the barriers must be stored somewhere. This requires space for storage and training to ensure employees know where the flood barriers are in a flood risk event.
  • Ground conditions – the ground conditions need to offer a flush threshold for the flood barrier to seal against, therefore the ground conditions needs to be considered prior to installation. This is a factor that is highlighted in a flood survey, and can be rectified by installing a metal floor plate when installing the flood barriers.

How much does it cost to build a flood wall?

The cost of a flood wall will depend on the height of the wall and the overall length. It is possible to create a flood wall out of demountable aluminium flood barriers.  If you do not require a demountable solution, then it maybe best to create a concrete bund around the asset, with a demountable flood barrier or floodgate at an entrance point.
