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.

Base for turf system

An artificial turf system includes a turf assembly having a turf backing and stands of artificial grass blades extending from the turf backing to form an artificial turf layer. Infill material is placed in between the blades of artificial grass and on top of the turf backing. The infill material has a composition of sand in an amount within the range of from about 80 to about 98 percent of the infill by dry bulk weight, and organic particles in an amount within the range of from about 2 to about 20 percent of the infill by dry bulk weight.

Infill for artificial turf system

An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.

Underlayment panel having drainage channels

An artificial turf system includes a turf assembly having a turf backing and artificial grass blades extending from the turf backing to form an artificial turf layer. Infill material is placed in between the blades of artificial grass. The infill material includes a plurality of wood particles, each particle defining a length dimension greater than a width or a thickness dimension. The length and one of the width or thickness dimensions defines an aspect ratio within a range of 1:2 to 10:1. In certain embodiments, the infill wood particles have a generally rounded edge profile along at least the length dimension. Each particle length dimension is oriented generally parallel to a grain structure of each particle. The plurality of particles maintains a water absorptive property that permits water to be retained by the particle and released over time to disperse heat from the infill material.

Underpayment panel having drainage channels

An artificial turf system includes a turf assembly having a turf backing and stands of artificial grass blades extending from the turf backing to form an artificial turf layer. Infill material is placed in between the blades of artificial grass and on top of the turf backing. The infill material has a composition of sand and organic particles. The infill material organic particles includes a plurality of wood particles where at least a portion of the wood particles define a length dimension oriented generally parallel to a grain structure of the wood particles. The length dimension is greater than a width or a thickness dimension and, in one example, may be in a range of about 0.5 mm to about 10 mm. The length dimension and one of the width or thickness dimensions may, in another example, define an aspect ratio within a range of 1:2 to 10:1.
