After the raising of the retaining walls, the teams proceeded with the backfilling. It will protect the walls from moisture and water thanks to a drainage device.

The visible part of the retaining wall, which will face the ornamental basin, is treated with stamped concrete. Forged concrete consists of applying a kind of giant stencil to a still fresh support (traditional concrete screed).

This technique makes it possible to enhance the landscaped surroundings of the resort.

Unlike stamped concrete, which can be used to create three-dimensional relief effects, stamped concrete can be used to draw two-dimensional patterns. This application technique offers significant robustness and durability qualities. A finishing varnish will be applied to the stamped concrete to waterproof it, fix the colours and facilitate its maintenance.

The Valenton station has a particularity. Its positioning will make it possible to slightly reorient the line towards La Végétale station. But it will also offer a new point of view on the city.
