180 post-tensioning shells, shaped like a folded sail.

12.40 x 1.80 x 3.00m high.

These shells in steel-fibre BSI®, 50mm thick, are used as covering materials for the treatment basins. The BSI® material was chosen for its watertightness and its exceptional resistance to the aggressive agents emitted by the waters contained in these basins. 70 thin lattices, 3.50 x 3.20 (minimum thickness 25mm).

These lattices are produced in white steel-fibre BSI®. The BSI® makes it possible to do without reinforcing bars, and provides complete resistance to an aggressive environment.

80 support frames, 3.00 x 2.40.

These frames in steel-fibre BSI® bear the shells. The use of BSI® makes it possible to reduce the dimensions of these elements.
