With the acceleration in the number of storms raging throughout France, with the Kirk Depression as the most recent episode, many owners are choosing to install cofferdams in their homes. These kinds of tailor-made anti-flood dams are the specialty of the Interalliance company, founded in Treillières almost 30 years ago. Today, they are receiving more and more requests.
“For me, it was vital”
A year ago, the garage of Thierry, a resident of La Baule, was flooded. The water rose to 1m30,”My car was floating” he said, when he came to see the damage. Even if the block in which he lives is not considered a flood zone, his garage, located on a slope, bore the brunt of the previous storms, “I told myself once, but not twice“. After some information, he chose to install this anti-flood dam at the top of the slope of his garage. Custom-made, it occupies 5 meters in width and 40 centimeters in heightwhich is enough to stop the water when a flood is predicted, “For me it was vital, now I sleep better at night“. To install the dam, simply insert the aluminum plates into the guides fixed on the walls. To free the passage, it takes around ten minutes to be able to remove them.

It took 4 to 5 weeks between the quote and the installation of the device, which cost him nearly 4,000 euros” For me it’s insignificant compared to the peace it brings us. ” recognizes Thierry. However, the Baulois was not able to benefit from the Barnier fund, which can cover up to 80% of the envelope. This boost helps people living in areas considered to be floodable.
“It’s certain that storms are an accelerator”
Today, the Interalliance company carries out between 15 and 20 poses per week“We will rather directly protect entrance doors, garages, sometimes even windows” explains Florian Merlhès, commercial manager for flood protection. He recognizes that with the various bad weather conditions, sometimes violent, owners are turning more and more to this type of device, “It’s clear that storms are an accelerator. People also feared that it would happen again. Sometimes all it takes is a storm and we’ll have a day with a lot of calls.” he explains.

Dependent on different weather phenomena, Interalliance is now called upon for interventions throughout France, “Now we move around a lot. We work on the seafront, but today we have also been called a lot to Nord-Pas-de-Calais with what happened, we are also going to Cannes. As soon as we are subject to weather fluctuations, it is obvious“.
