Technical and aesthetic drainage solution

Place Sainte Anne-Rennes

If you visit Rennes, the one place you must see is Place Sainte-Anne, located in the northern part of the city’s old town. This square is home to an enormous church called the Basilique Notre-Dame de Bonne Nouvelle de Rennes.

In this spectacular square, we installed ULMA drainage channel systems with two objectives in mind: to provide a technical solution for draining rainwater, and to do so using an aesthetically pleasing grating.

Technical drainage: MultiV+ channels (and why they should interest you)

First, I will tell you about our most widely used system - MultiV

- Durability over time: Made from polymer concrete, they are up to four times more durable than traditional concrete channels. As such, the drainage system will last much longer.

- Reduced cleaning costs: the optimised V-shaped channel causes the water to drain faster, helping to remove sediment more effectively and thus provide self-cleaning properties. In other words, these channels require less maintenance because they clean themselves.

- Savings on labour costs: thanks to the Rapidlock® screw-free fixing system, the grating can be fixed to the channel in just a second, with no need for tools. Quick and easy.

For Saint-Anne we supplied two different models from the MultiV+ range: The R200GH1 channel model with a mixed slope and low-profile channels.

So, how did we meet the aesthetic part of this challenge?

Since this is an urban environment, the appearance of the grating was an important factor. In this case we installed heel-proof longitudinal slotted gratings – maybe we should advise the part number of this grating ?. This type of grating is equipped with 45° water directing slits and pivots and has a catchment area of 720.55 cm²/ML.

So now you know: if you visit Rennes, make sure you stop by Place Sainte-Anne to appreciate the urban landscape, enjoy a crêpe and, while you're there, look down and you'll see our drainage solutions
