A third-generation sports surface uses silica sand and rubber granules in the infill to cushion the ball and give a more realistic bounce – this is a feature that makes these types of surfaces very popular with football clubs. However, the pile height of the artificial grass is often much higher than that of a domestic fake lawn and this can be an issue for goalkeepers. This is where a 3G Pitch Resurfacing can be a great investment as it will restore your surface back to its peak performance.
The Science Behind 3G Pitch Resurfacing: What You Need to Know
This process involves digging up the current synthetic surface and installing a geotextile membrane, drainage layer, MOT type 1 sub base and a macadam or rubber shock pad. A new 3G surfacing with the appropriate infill can then be laid over the top of this. This is typically a silica sand and rubber crumb mix but the exact type can vary depending on whether the pitch will be used for football, rugby or hockey. For example, hockey requires a lower infill to ensure the surfacing is quick and responsive.
The maintenance program for a 3G football turf pitch should also include specialist cleaning techniques to prevent the infill from migrating to the perimeter of the surface and becoming exposed. The best option for this is a Power-brush procedure using a machine that can rotate the brush head in a counter-rotating fashion to lift and agitate the rubber infill and help to keep it secure on the turf. This should be carried out at least twice per month.
