The pool has a central circular portion formed by a cylindrical structure (7) comprising juxtaposed metal plate components. This is surrounded by a concentric outer structure formed by similar, height-adjustable component assemblies (2,3). The space (8) between the two structures is filled by an incompressible material which contains no cement substances. A PVC membrane (10) extends over the structures to form a sealing layer, including a reinforced portion (11) for securing to the outer structure. ADVANTAGE - Simple, rapid installation with adjustability of dimensions.
