In USA, either high-class PA material or polyester fiber are used as the artificial grass fiber material for most artificial turf. While the infill-free artificial turf can be divided into two types as water permeable and water impermeable. This kind of artificial turf looks quite similar to the natural grass lawn, some of which are attached with a layer of shock pad at various density and thickness.

Due to the current situation that there are few domestic manufacturers who have really mastered the technology for installation of artificial turf and most of technology was brought in from abroad, the process of laying the sand infill-free artificial turf especially the shock pads will have to be completed by the overseas experts. Beneath the shock pads is a layer of smooth asphalt base, below which is another base of mixed rubble, sands and pebbles. Among these the structure of drainage system is the most essential part. Besides, exclusive machines for artificial turf need to be used during the process of installation on this type of pitch, especially on some professional or expensive sports fields, in order to meet the demands of flat level and evenness for the filed. For instance, the hockey pitch in the Beijing Lucheng Sports Technological College as the hockey training court for 2008 Olympic Games and some other fields like mobile artificial turf and pieced artificial turf lawn  which need to satisfy the special requirements, all must comply with the aforesaid strict demands for the field installation.
