Base for turf system
DCFirst Claim
1. A turf underlayment layer comprised of an assembly of panels, 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 shaped with a recess for interlocking with one or more adjacent panels in the assembly of panels, and 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.

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 fluid flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

A turf underlayment layer comprised of an assembly of panels, 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.
- 14. A turf underlayment layer comprised of an assembly of panels, 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 edges of the panels being shaped so that where the edges of a panel abut the edges of an adjacent panel in the assembly of panels the edges of the panels form a drainage slot capable of allowing water to flow from the top side of the panels to the bottom side of the panels.

18. A turf underlayment layer comprised of an assembly of panels, 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 a lower surface that extends across the bottom side of the panel to allow drainage of fluid across the bottom side of the panel, the edges of the panels being shaped with a recess to mate with the edges of similar panels to form a drainage slot capable of allowing water to flow from the top side of the panels to the bottom side of the panels, 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.
