Demountable flood barriers are commonly used in residential and commercial flood mitigation to protect doors and access points from flooding. Rather than build a permanent flood wall that can reduce access and alter the landscape, demountable flood barriers are only erected in flood risk situations. This means in normal situations the scenary is unaffected and can be enjoyed by the public. This ensures the aesthetics of the area or your property are maintained.
Demountable flood barriers are also called removeable flood barriers. Removable flood barries have aluminium panels which slide into two upright fixings. The upright fixings are permanently fixed into a solid wall, however the span between the two upright fixings is clear. This ensures an access point or view is unobstructured in normal conditions. This is commonly used in loading bays and garages, but also on river or tidal banks.
Advantages of demountable flood barriers
- Quick and easy to install
- Flexible and adaptable
- Reduce the aesthetic impact on your surrounding area
- Lightweight – the demountable flood barriers can be lifted by a single person
- Locks available – if you require the flood barrier to be left in position, we can provide a locking mechanism to ensure they are not stolen.
- Long life – aluminium is a robust material will last
- Powder coat to any RAL colour
Demountable flood barriers are made from aluminium, making them robust and reliable. The benefit of manufacturing in aluminim is the boards can be made to any width required, and with the use of demountable posts can be extended to any length. There are a range of heights available, from 200mm – 2000mm.
The Buffalo Flood Barrier can incorporate 90 degree demountable posts, which means you can create flood bunds around assets or compounds around doors. By building a compound around a door with flood barriers, you can allow for access to the door even in a flood situation. This is common when installing flood barriers around fire doors or main entrances.
The demountable posts sit within a 150mm diameter hole, which is 300mm deep. This is core drilled out of the ground, and an aluminium insert left in the hole with a ground cap. The ground cap ensures the ground is level and no trip hazard.
Common Uses of Demountable Flood Barriers
The benefit of aluminium flood barriers is they are versatile and can be used on any property (residential or commercial). The most common use of demountable flood barries are:
- Loading bays
- Sliding doors
- Flood Bunds around assets
The demountable flood barriers can also be used against tidal surges.
How many demountable posts do I need?
The demountable post is required depends on the type of system. The standard Buffalo Flood Barrier requires a demountable post every 1.8m. The HD version is thicker, and therefore can withstand greater pressures and requires a demountable post every 2.4m.
If the flood barrier is going to be located aginst strong tidal surges, additional re-enforcing posts may be required to manage the wave impacts.
