Blue double security flood door with push bar and red toggle clamps in a switch room

Passive Protection

The majority of flood defence failures are the result of an error during deployment. Our flood doors design out this risk. If the user is capable of opening and closing a door, then they are capable of deploying a flood door.

 

Security certified to LPCB 1175

Industrial doors often are the last line of defence for a sensitive asset. We’ve designed, tested and certified a range of security flood doors, offering industry-leading protection from flooding and intruder entry. Flood protection without compromise of site security.

 

Full-height flood defence

Flood heights vary greatly from project to project - sizes too. Our design team is flexible to your needs, capable of designing to withstand up to a full-height head of water. Any flood door supplied by MM Engineering is made precisely for your site, so you can guarantee flood defence that’s right for you.
