The invention relates to a floor underlayment comprising a first layer, a second layer, and an inner layer between the first layer and the second layer, wherein the inner layer has one layer of foam beads, and the floor underlayment has a thickness from 0.8 mm to 1.5 mm. The invention further relates to a method for manufacturing a floor underlayment, a flooring system and a use of a floor underlayment.

A method and system for providing an artificial turf edge. In one embodiment, the system includes: a first raised border piece having an S-shaped cross-section and a first coupling mechanism formed on a first rear surface of the first raised border piece; a second raised border piece having an S-shaped cross-section and a second coupling mechanism formed on a second rear surface of the second raised border piece; and a connector piece configured to be coupled to the first and second coupling mechanisms, thereby coupling the first and second raised border pieces together, wherein top surfaces of the first and second raised border pieces are configured to be coupled to a piece of artificial turf so as to simulate an edge of a real grass lawn.

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises plurality of panels, each panel comprising a core with a top side and a bottom side. The top side has a plurality of top projections. The top projections form top side water drainage channels. The panels have edges, with the edges of one panel abutting the edges of adjacent panels, thereby forming a drainage path between adjacent panels. The panel edges have vertical support extensions that extend into the drainage paths between adjacent panels. The vertical support extensions have an upper surface for supporting an artificial turf assembly overlying the turf underlayment layer, and the panel edges having one or more complementary indentations corresponding to vertical support extensions of adjacent panels. When the panels move toward each other, thereby closing drainage paths between adjacent panels, the vertical support extensions are received in the corresponding indentations.

A splash pad has a plurality of interlocking pallet assembly modules with each pallet assembly module having a supporting body and a water permeable layer and each water permeable layer connects to at least one adjacent water permeable layer to form a continuous water permeable walking surface. At least one tubular dispenser has at least one nozzle extending through the splash pad continuous water permeable walking surface. A pumping station has at least one pump and at least one water intake device. The splash pad, the tubular dispenser, and the pumping station inserts into a recession having water therein. The water intake device provides water from the recession to the at least one pump, so that the pump can drive water through the tubular dispenser to project through the nozzle onto the splash pad continuous water permeable walking surface.

The invention relates to a method for the construction and sustainable management of a hybrid turf sports ground, with management of a shallow water table in the structure of the sports ground, which comprises: a first step of constructing a structure (S) placed on a base (F), the structure comprising N stacked porous layers (Ci); a second step of installing turf on the surface of the top layer (Ci), the installation of the turf possibly being carried out by sowing; and, of the N layers, one hybrid layer (H) is constituted either (i) by a cultivation substrate that comprises synthetic reinforcing elements, or (ii) by a cultivation substrate that shares the space of the hybrid layer (H) with synthetic reinforcing elements.

A poured-in-place protective surface, such as can be installed at a playground, includes an impact-attenuation or cushion layer, which comprises a blend of (a) a rubber chunk component made up of granules of reclaimed rubber, the reclaimed rubber being from non-tire sources; (b) a tire buffings component; and (c) a binder. The ratio of rubber chunk component to tire buffings component is selected to be between 1.25:1 and 10:1, and more particularly between 1.25:1 and 5:1.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.
