Abstract: A multi-layered sports playing field including a top layer made of substantially artificial material simulating a natural playing surface such as grass and a padding layer positioned between the top layer and the base or dirt layer. The padding layer is made of a plurality of discrete beads of substantially elastic, resilient material (e.g., foam) with portions of adjacent beads abutting one another and other portions being spaced from each other. Substantially all of the adjacent beads are preferably integrally joined (e.g., glued, fused) together at their abutting portions. The padding layer is very porous and breathable and preferably includes feet members supporting the main body of the padding layer above the base or dirt layer to create a water channel of interconnected portions to enhance water drainage to the sides of the field.

Abstract: A modular construction system that provides structures utilizable in the manufacture of bases for pavements, pavements, slopes, canals, walls, arches, and bridges. A flexible structure is obtained formed by the articulated and indissoluble union of a multiplicity of identical modular units that have articulated, unbreakable joints, although there are free spaces between the units, in such a way that when a weight is placed in any area of the flexible structure, a part of the load is immediately distributed to the adjacent areas, the structure thus resulting in a stress distribution system, being flexible, articulated, and indissoluble. The distribution of stresses occurs both in the horizontal and the vertical direction. Two or more structures can even be placed one on top of the other, duly articulated between each other, with a separating layer between each one of them, by means of latch pins such as to allow the structure to be flexible, functioning in a manner similar to how a single structure functions.

Abstract: Various embodiments for a pad that may be combined with other similar pads to form a padding layer of an athletic field, or other surface, are disclosed. The pad includes a top surface and a bottom surface. Bottom-side projections are positioned on the bottom surface of the pad. Water channels are positioned on the bottom surface of the pad defined as a recessed area between individual ones of the bottom-side projections. A drainage hole is positioned in at least one of the bottom-side projections such that the drainage hole does not connect with any of the water channels on the bottom surface.

Abstract: 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.

Abstract: A dual-unit paving system for covering a surface is provided. The system comprises pairs of first and second units. For each pair, the first and second unit have different respective shapes and sizes, and are configured to be matingly engageable for forming a hexagonal assembly having six, non-linear sides. The hexagonal assembly allows forming rotational tessellations. The first and second units are also shaped and configured to be matingly engageable so as to form horizontally aligned tessellations, and also vertically aligned tessellations.
