The nidasport® panels are extruded polypropylene honeycombs with an 8mm mesh covered on both sides with a porous geotextile. These polypropylene honeycomb panels are designed to provide a base for an artificial turf layout, with or without an intermediate shock absorbent layer for use as playing fields. They can be used to create a flat porous surface, which provides a base for artificial turf sports surfaces. In addition to storing rainwater (95% of empty space), they have excellent shock absorption properties. These nidasport® panels can be used as an alternative construction to traditional playing fields, renovating sports fields or constructing a rooftop sports surface.
