SILICA SAND FOR ARTIFICIAL GRASS The sand is used for both tennis and football artificial turf and therefore 2 different granulations are used: 1. Tennis: sand 0,4-0,8 mm (should not exceed 1,00 mm in any case). 2. Football: 0,5-1,25 mm (should not exceed 1,50 mm in any case). Generally, the silica sand granulation depend on the density of the synthetic grass, when the grass is quite dense ( more than 45000 stitches) we have to use the smaller granulation ( 0,5-0,7 mm) . so that the sand can be placed into the grass pile when the grass is very dense, the sand cannot be placed inside In case of lower density ( soccer around 10 000 stitches), you can easily install the bigger granulation, but never higher then 1,5 mm ( even though some companies install even bigger but it is not according to any standards or international requests).
