Publication number: 20240117572Abstract: 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.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Applicant: Brock USA, LLCInventors: Steven Lee Sawyer, Daniel C. Sawyer, Richard R. Runkles

Publication number: 20240003100Abstract: 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.Type: ApplicationFiled: September 19, 2023Publication date: January 4, 2024Applicant: Brock USA, LLCInventor: Steven Lee Sawyer
