Structural underlayment support system and panel for use with paving and flooring elements

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 including a top side having a plurality of projections, a bottom side, and panel edges, the plurality of top side projections forming top side channels that extend across the top side of the panel to allow drainage of fluid across the top side of the panel, and the bottom side having bottom side channels that extend across the bottom side of the panel to allow drainage of fluid across the bottom side of the panel, the panels being made from a plurality of polyolefin beads, the plurality of polyolefin beads bonded together by at least one of pressure and heat to produce a substantially water-impervious surface.
