1. A paving system for paving comprising:
a top layer of a plurality of paving elements; and an underlayment support layer in the form of panels positioned underneath the top layer, the panels being made of a core with a top side and a bottom side, the core being made from expanded polymeric bead material that is substantially impervious to fluid flow, but the panels having spaced apart drainage holes that interconnect the panel top side with the panel bottom side such that the overall underlayment layer is porous to the flow of fluids, the panels having a plurality of projections extending across the bottom side of the panel, the projections forming bottom channels suitable for water drainage flow.
