A customizable playing field includes a turf system comprising a tile with a turf layer. The tile overlays a subfloor, defining a reservoir thereunder. A forced air system includes a pipe disposed within the reservoir and operatively coupled to a pump; and a sensor. A control system controls the pump, and includes a processor in data communication with at least one input/output device and computer memory. The computer memory has a program with machine readable instructions that, when effected by the processor, perform the following steps: if the temperature is above a predetermined threshold as measured by the sensor, forcing a cool fluid through the pipe; and if the temperature is below a predetermined threshold as measured by the sensor, forcing a warm fluid through the pipe.

The invention provides for method for forming an artificial turf infill material. The method comprises selecting from a zeolite ore a microporous zeolite mineral using a selection criterion on specific surface area of the mineral, thereby providing the artificial turf infill material.

A sheet for use in ground works, the sheet having an upper face with an plurality of openings therein, a lower face configured so as to permit liquid to drain through the sheet and a spacing arrangement to separate the upper face from the lower face and define a volume therebetween, where the volume is capable of receiving an infill material via the openings in the upper face. The lower face of the sheet is configured to be interengageably secured to an upper face of a similar further sheet.

The present invention provides a pavement deicing or snow-melting system, comprising a water-permeable pavement, a drainage device and a heating device, wherein the water-permeable pavement comprises, successively from the top down, a water-permeable asphalt concrete coating, a porous cement stabilized macadam layer, a reflecting layer, a waterproof layer, a semi-rigid base and a semi-rigid cushion; the drainage device comprises a drainage ditch and a sheet cover; a water inlet is formed on the drainage ditch; a lower edge of the drainage ditch is not lower than the waterproof layer; curbs are arranged on edges of the water-permeable asphalt concrete coating and the porous cement stabilized macadam layer; and, the heating device is arranged between the water-permeable asphalt concrete coating and the porous cement stabilized macadam layer.

Systems and methods for a ground water filtration system are described. The ground water filtration system includes paver blocks designed to facilitate liquid seepage between the paver blocks and to route the seepage to a preferred area. A filter may be utilized to remove undesired particulates in the seepage prior to routing. The ground water filtration system additionally provides at least one layer of stone to facilitate flow direction of the seepage. At least one geogrid fabric is also provided to further enhance ground water filtration.

A structural system that includes at least two pavers partially defining a paved surface, the pavers partially defining a void between them. The system also includes a permeable joint located in the void between the pavers, where the permeable joint also partially defines the paved surface. The permeable joint includes a base layer formed of aggregate and bonded together with a non-cement binder, and a membrane layer formed of aggregate that is sized smaller than the aggregate of the base layer, where the aggregate of the membrane is also bonded together with a non-cement binder. The membrane is less permeable than the base layer and is located above the base layer.
