Abstract: The invention relates to expandable polystyrene particles which contain foaming agents and are coated with 0.01 to 0.5 wt. % of a waterproofing agent which melts above 10 DEG C and has an average particle size of less than 100 mu m. The particles are processed to form moulded foam structures with a reduced water absorption capacity.
