The surround is made from strong and supple hollow plastic material (2) with cavities (CS, CI) connected to an inlet (OR) and an outlet (OV) for filling with water or compressed air, while projections (SI, SS) provide for even pressure distribution. The lower surface of the surround is attached to a base (1) designed to be fastened to a concrete surface (Bet). The surround has a rounded edge (G) and in a variant can project into the pool.
