Floods and storm surges can cause damage to businesses and lead to costly repairs. Flood barriers protect the building and its contents from water damage. There are many flood defense designs to choose from, each with its own advantages and disadvantages. Design professionals are able to recommend the perfect solution for any business.
Removable Barriers
Removable barriers are kept stored away until they are needed. They are typically made of aluminum panels. Anchors and screws are pre-installed so that the panels can be attached. Water tight gasket material creates a tight seal. This type of barrier can protect buildings from water levels up to 7.5 feet and can be joined together to accommodate any width.
Another type of removable barrier consists of material that is zipped together to form a water tight seal. The advantage of this type of design is that a few people can install it quickly. Like the aluminum panels it can be designed to any width, yet its water height is 5.6 feet.
Businesses that are in a heavy impact or high velocity zone will benefit from a removable system that totally surrounds the building. It has interlocking panels that can be designed to protect against almost any water level. These are loads calculated based on flood conditions.
When flooding from rivers is a concern, a lightweight barrier that can be mounted to a frame on the building is a good choice. The flood guard can be clipped to the frame in minutes. This system often uses the arch-dam principal. This means that as the pressure and water level rise, the frame seal becomes more efficient.
Passive Barriers
Doors for pedestrians fall into this category. They are a flood barrier and are made of steel. They can even have glass inserts.
A floodbreak is a barrier that is a hinged box that is recessed into the ground. Rain from storms is funneled into the box and then is allowed to drain away. When severe storms cause the box to fill up with water the lid will rise and lift the barrier. As the water recedes the barrier will lower.
Just like the flood break, a self closing floodwall requires no human intervention in order to work. When there is a flood, it responds automatically. The floodwall is great choice for flash floods. Neither passive design requires electricity.
Hinged Barriers
Hinged gates are usually made of lightweight aluminum but can also be made of steel. They are commonly used at vehicle entrances and ramps.
Pivot gates are operated by lever using a gas-lift mechanism. This barrier is great for protecting wide openings like loading bays from flash floods.
There are many flood barriers to choose from when it comes to protecting buildings from flooding. The businesses requirements and the local flood conditions will determine the best barrier.
