The procedure comprises making a one-piece solid plastic inner layer, and spraying with outer layer of plastic in liquid form, followed by hardening. This is followed by an application of resin and glass fibres, either separately or simultaneously, and then a top coat (8). The procedure consists of making a one-piece solid plastic inner layer (5), pref. by rotomoulding, and spraying it with an outer layer of plastic in liquid form, followed by a hardening stage. This is followed by an application of resin and glass fibres, either separately or simultaneously, and then a top coat (8). Connecting inserts and fluid detectors (6a) are embedded in the inner layer during its manufacture and the inner layer is transported between different work stations for the different stages to be carried out. The completed tank is polymerised by stoving.
