Abstract
An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for water flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.
Claims24
A turf underlayment layer having panels including a top side having a plurality of projections, a bottom side having a plurality of projections, and panel edges, the plurality of top side projections forming top side channels and the bottom side projections forming bottom side channels, the panel edges configured to abut edges of adjacent panels, the panels further including a plurality of drain holes dispersed over the panel surfaces for fluid communication between the top side and the bottom side of the panel, the drain holes positioned to intersect both the top side and bottom side channels to connect the top side channels to the bottom side channels, wherein the panels are 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.
A turf underlayment layer having panels including a top side having a plurality of projections, a bottom side having a plurality of projections, the top side projections and bottom side projections terminating in generally flat support surfaces having different sized support surface areas, and panel edges, the plurality of top side projections forming top side channels and the bottom side projections forming bottom side channels, the panel edges abutting edges of adjacent panels, the panels further including a plurality of drain holes dispersed over the panel surfaces for fluid communication between the top side and the bottom side of the panel, the top side projections and bottom side projections being spaced apart and sized such that the top side channels intersect with the bottom side channels at the drain holes, the drain holes positioned to intersect both the top side and bottom side channels to connect the top side channels to the bottom side channels, the top side channels including a roughened surface texture.
