The panel (1), which can be flat or in a convex or concave curve, has an anchoring lip or sole (4) running along the length of its lower edge that forms part of the swimming pool base. The panel also has lengthwise reinforcing elements above the lip, an upper rim that faces in the opposite direction to the lip, and vertical returns (8) at its ends, pierced with holes for (9) assembly rods. The lip can be covered with cast concrete (5) when the panels are assembled inside an excavated pit.
