Flood Doors and Flood protection

1st Defence doors are designed, manufactured and customised to your needs. Whether its for heavy industrial or domestic use, the level of flood protection and quality is the same. Our range of doors are designed using the latest design techniques combined with steel or stainless steel allowing them to be suitable for all situations.

What are Flood Doors?

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

Flood doors can replace ordinary doors that are already part of your business site. They can also be added to spaces between walls to provide extra protection when there is a flood risk.

Generally, flood doors are built into a structural wall within your premises to provide a unbroken flood barrier against flood water. This provides a defence against flooding, which is especially important in areas near at risk of flooding with heavy rainfall.

Flood doors can help prevent the most serious damage to your premises by preventing large, forceful flows of flood water into your business.

It is important that the doors in 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.

We can offer you the following door types

Flood Door or Flood barriers?

Flood barriers & gates are an alternative to projects where there may be a greater need for larger flood protection.
