What are Floodgates?

It might sound like an obvious question, but there are a variety of different flood defence systems that meet different requirements and prevent flooding.

Floodgates can replace ordinary gates that attach to the perimeter walls of your business site. They can also be added to spaces between walls and closed only when there is a flood risk. They can be built for pedestrian or vehicular access.

Generally, the gates are built into the structural wall surrounding your premises to provide unbroken flood barrier against flood water. This provides perimeter defence against flooding, which is especially important in areas near rivers at risk of bursting their banks with heavy rainfall.

We can help prevent the most serious damage to your business premises by preventing large, forceful flows of flood water onto your business site.

It is important that the perimeter walls surrounding your business site are strong enough to withstand flood water. A fast flow of water has a huge amount of energy and can easily damage existing walls, especially if they have already been weakened by previous flooding.

1st Defence Sliding Gate systems.

Sliding floodgates are an alternative to projects where there may be an opening restriction or due to the size, a safety issue. The sliding flood gates can be concealed between flood defence walls, allowing a better aesthetic and are used for instances where the gate will only be seen when needed, such as high tides or storm surges.

Our floodgates offer a Safety threshold design. All our gates have a flush threshold to prevent the need for a step. This forms the seal allowing easy vehicular access on larger gates and trip free access for pedestrians.

The sealing sill of our floodgates is a anti-slip plate allowing vehicular and pedestrian access with no trip hazard. The floodgates seals are created using a custom protection foam with a protective sleeve to prolong the life of the seal.

We also use our gate expertise to produce flood doors and security products for your property care.
