Abstract
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.

A paving system for paving comprising:
- a top layer of a plurality of paving elements;
- an underlayment support layer of a polymeric material from an expanded bead material configured into panels, the panels being positioned under the top layer and having sufficient rigidity to disperse concentrated loads of the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration and then removed returns the support surface to a generally planar condition, the panels being made of a core with a top side and a bottom side, the panels having drainage holes that interconnect the panel top side with the panel bottom side such that the underlayment layer is porous to the flow of fluids.
A paving system for paving or flooring comprising:
- a top layer of a plurality of paving elements;
- an underlayment support layer of a polymeric material from one of a polyethylene and polypropylene expanded bead material configured into panels, the panels being positioned under the entire top layer and having sufficient rigidity to disperse concentrated loads of the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration and then removed returns the support surface to a generally planar condition.
A paving system for paving or flooring comprising:
- a top layer of a plurality of paving elements;
- and
- an underlayment support layer of a polymeric material in the form of expanded beads bonded together by at least one of heat and pressure and having a density in a range of from about 50 to about 60 g/l and configured into generally rigid panels, the panels having a plurality of projections extending across a bottom side of the panel, the projections forming channels suitable for water drainage flow and having an edge configuration sufficient to interlock adjacent panels and to permit fluid communication of the bottom side channels of one panel to the bottom side channels of the adjacent panel.
A paving system for paving or flooring comprising:
- a top layer of a plurality of paving elements;
- an underlayment support layer of a polymeric foam bead material configured into panels, the panels having a generally planar support surface and being positioned under the entire top layer, the panels having sufficient rigidity to disperse concentrated loads of the paving elements and a recovery characteristic that mitigates a permanent compression applied directly to the panels from a walking or kneeling event during installation of the paving elements such that the support surface of the panel returns to a generally planar condition.
An underlayment support panel for a paving system, the underlayment support panel being made of a polymeric material from one of a polyethylene and polypropylene expanded bead material, the panel having sufficient rigidity to disperse concentrated loads of superimposed paving elements, the panel having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration and then removed returns the support surface to a generally planar condition.
