In flood-prone areas, keeping people safe is a legal requirement for many sites: campsites, leisure facilities, business premises. The flood refuge platform (or refuge area) provides a raised space where people can wait safely for the emergency services.
What is a flood refuge platform for?
- Sheltering occupants above the highest known flood level.
- Meeting the requirements of a flood risk prevention plan or of the local authorities.
- Allowing evacuation by the emergency services, including by helicopter depending on the configuration.

A structure designed for outdoor use
A refuge platform is usually installed outdoors. It must withstand bad weather, wind and the force of water. We design it with corrosion-protected steel (galvanising or a suitable paint system), concrete pad foundations sized for the site and an anti-slip deck.
Accessible to everyone, even in an emergency
On the day of the flood, access must be quick and simple. Wide stairs, handrails, guardrails, ramps where needed: the platform complies with accessibility and evacuation rules, like a public-access mezzanine. Its capacity is calculated for the number of people to be accommodated.

Your questions
FAQ: flood refuge platform
Who has to install a flood refuge platform?
In France, campsites and some establishments in flood-prone areas may be required, by the flood risk prevention plan or the local authorities, to provide a raised refuge area. Check with your local authorities.
How is the capacity of a flood refuge platform calculated?
The area is determined by the number of people to be accommodated. The structure is then designed for this load, as well as for wind and snow, to the Eurocodes.
How does an outdoor platform resist corrosion?
The steelwork is protected by hot-dip galvanising or by a paint system suited to outdoor environments. The deck is anti-slip and free-draining.
