Artificial grass surfaces are available in many lengths and are used for a large variety of sports. Needle punched surfaces are generally short pile (8 to 15mm) and are used for football, tennis, hockey, netball and cricket. They may also have a shock pad base to improve the shock absorbency. Tufted carpets vary in pile height from 7 to 65mm, and are used for football, tennis, hockey, netball, cricket and rugby. They may also have a shock pad base to improve the shock absorbency.
The sand filled surfaces, with pile heights typically 20 to 24mm, require regular brushing. The interval depends upon the surface usage, but can be as regular as every week. In addition, the surface requires chemical treatment and deep cleaning throughout its life, and may even require complete sand removal and replacement if contamination is widespread.
Sand dressed carpets are predominately a surface designed for hockey, but are also used where football is a secondary sport. The surfaces, usually with pile heights between 15 and 20mm, have less sand than the filled surfaces and can have faster play characteristics, ideal for hockey. As with sand filled, these carpets require regular brushing as well as chemical treatment and deep cleaning.
3G surfaces are the newest addition to the artificial grass surfaces. These are sand and rubber filled carpets ranging in length from 35mm to 65mm. All are generally used for football, but the shorter versions can be used for hockey practice. The surfaces require regular brushing, particularly prior to hockey being played, but again the regularity will depend upon usage. As the rubber granules are a loose infill, they may migrate off the surface and on to surrounding areas. The granule levels may therefore require topping up from time to time.
Needle punched artificial grass generally has a short pile (8 to 15mm) and with a dressing of sand. These surfaces can be used for multi sport purposes and generally require minimal maintenance. They require chemical treatment and brushing to ensure dirt and general debris is removed from the surface.
Water based artificial grass are surfaces which are used for competitive hockey and generally have a pile length of 10 to 15mm. Due to the regular use of water, moss and algae growth can present contamination issues which are reduced with the regular use of chemical treatment and deep cleaning of the surface.
