FloodFlash visit flood resilience partners M3 Floodtec

Earlier this year, a few of the FloodFlash team got up especially early to visit one of our partners – flood resilience experts M3 Floodtec. We spoke about flood insurance in the UK, and how flood resilience plays an important role in protecting commercial properties. 

Who are M3 Floodtec?

M3 Floodtec are one of the UK’s leading flood resilience companies. They offer full turnkey solutions from design through to commission, or bespoke elements to an overall flood mitigation project.  

M3 Floodtec have an extensive range of solutions available. These include: 

  • Flood Doors – a 100% waterproof door with a patented sealing system. 
  • Anti-flood airbricks – bricks with an internal self-activating gate that automatically shut off in the event of a flood. 
  • Non-return valves – valves that only allow water to travel one way, preventing water from travelling up through underground pipes and drains. 
  • Flood barrier – barriers installed across doorways or other openings before a flood. 
  • Wall treatment – water-repellent treatment that creates a protecting waterproof seal on above ground walls.  

They also have a state-of-the-art research and development facility. This allows them to continually test their products and ensure they are up to scratch.

The Flood House and testing facility

After speaking about the flood insurance and flood resilience industry, the FloodFlash team were eager to get more hands-on with some of their flood resilience products. M3’s testing facility and Flood House demonstration centre provide visitors with the opportunity to do just that.  

We stepped into the house and shut the doors firmly behind us, waiting for the flooding to begin. The pumps released 30,000 litres of water in just 10 minutes.  The water reached a heigh of over 50cm before the pumps were turned off and the water could lower again. 

The waters reached 50cm outside the building, which we saw through the French doors.
The flood defences in place in the Flood House ensured the team stayed dry.

The £500,000 facility is BSI approved. It is open to visits from industry stakeholders, property owners, community flood groups, and the media. Flood mitigation manufacturers can use the facility to test their own products. This is revolutionary for the industry, as testing costs amount to £40,000, nearly half the cost of launching a new resilience product.  

How flood resilience interacts with flood insurance

Putting resilience measures in place can be expensive. It can be hard to justify the costs of flood gates, flood doors, air bricks, non-reverse valves and other measures, especially if you are already paying for flood insurance.  

Putting resilience measures in place reduces the costs associated with a flood. However, with traditional insurance, these measures rarely result in reduced premiums. This makes the significant costs of resilience measures even less justifiable. Factors contributing to traditional insurers being reluctant to offer premium reductions include: 

  • The uncertainty around the costs that floods may cause, and the impact resilience measures has on such costs 
  • A lack of trust in the installation and maintaining of resilience measures 
  • A lack of trust in the human element involved in implementing resilence measures, for example, putting up flood gates when a flood warning is received. 

At FloodFlash, we use parametric insurance, with flexible trigger depths and payout amounts. The flexibility of a policy means having resilience measures can significantly reduce premiums – by choosing higher first trigger depths or by reducing payouts at lower depths.

For example, a small business owner in a high flood risk area may want trigger depths at 20cm, 30cm, and 50cm. If they have 50cm flood gates, they could raise the first trigger to 50cm – the height those gates would be breached. This would significantly reduce their premium, as the chance of a 50cm flood is much less than a 20cm one. Alternatively, they could keep the 20cm trigger depth to account for business interruption during a small flood, but lower the payout amount.

Why we partner with M3 Floodtec

Our belief is that everybody should be able to recover from catastrophe. Our parametric insurance helps people to do just that by providing financial resilience. However, pairing insurance with the physical resilience measures discussed means a business has even higher chances of a quick recovery. 

400 properties were flooded across the country during Storms Dudley, Eunice and Franklin in February 2022. The installation of temporary flood defences protected an estimated 40,000 properties.

This statistic shows the importance of physical flood resilience measures, even simple flood gates. When coupled with parametric insurance, like FloodFlash, physical resilience allows higher trigger depths to be set, meaning lower premiums. Our hope is that the two can create truly flood resilient properties at an affordable price, enabling more businesses to survive flooding.
