A storage tank with a pre-insulated outer tank has been described, and a method for building such. For building a wall of an outer tank, a formwork is erected with an inner partition to which PVC-foam plates have been attached, which at their inner surface are provided with a coating provided with gravel. Subsequently, concrete is poured into the inner formwork space, which concrete attaches firmly to the gravel sticking out of the coating. On a floor, a coating layer is applied, over which a layer of PVC-foam plates is applied. Subsequently, a secondary monolithic coating layer is sprayed over those PVC-foam plates and onto the inner surface of the coated PVC-plates 10 of the wall.
