The swimming pools are made concrete (including the walls).The walls and the bottom are cast in only once to obtain a monobloc pool.
The lining can be coated or coloured earthenware (taking into account the acceptance of the Luberon Park).
For example the grey walls (color cement) give a dark green water, and ivory-coloured walls give a green torrent water.
The curbs can be performed in natural stones of regions which can age and skating.
