The aim of the invention is to provide a plate with a concave surface. Said plate is produced according to the hot adhesive press moulding method and preferably from recycling plastics in such a way that rain water and melt water is let off in the outer area towards the edges of the plate when the plate is used as a ground plate. According to the invention, the underside of the plate core (2) is coated with liquid artificial resin. One or more layers of a tissue (3) in the form of a thread guide, nonwoven fabric for instance, are inserted into the liquid artificial resin. The artificial resin is subsequently hardened. |
