The invention concerns a method for making a levelling device characterised in that it consists in: producing first and second parts (1, 3), the first part (1) comprising a planar surface (1a) provided with a first elongated concave portion (2) having a first (2a) and a second end (2a, 2b), the first end being at a distance d from the edge (1b) of the first part (1), the first part (1) and/or the second part (3) comprising a second concave portion extending over a length d from the edge of said first and/or second part; assembling said two parts (1, 3) to form a cavity (4) open at the first end (2a) of the first concave portion (2) and extending through a filling channel (6) at the second concave portion (2c); filling the cavity (4) with liquid via the filling channel (6); sealing the cavity (4) at the filling channel (6). |
