Cairo Minerals Offer High Graded and processed and sieved silica sand, which is natural grains.
Silica sand is processed in our own screening plant after Extracting and transported to our site for screening, in our site we can grade and meet all required practical sizes according to FIFA.
The silica sand for artificial grass has become Hot Request in the last 5 years which means high World production of artificial grass and replaces natural grass. FIFA has Encouraged and Recommended using Artificial grass instead of Natural grass ,for that Reason Silica sand has been ordered from many buyers ,included football federation ,individual companies, Sports Clubs, landscaping, Houses
Silica sand is used for Artificial Grass and Football pitches, beach volleyball, tennis court, tennis soccer.
What is common sizes of silica sand are normally used in filling 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).
• What is common sizes of silica sand are normally used in filling beach volleyball?
silica sand for beach volley, normally here simply use the
Sand from the beach on seaside (I suppose that should be the same granulation as for football synthetic grass).
• What is common sizes of silica sand are normally used in filling tennis court and tennis soccer?
I already explained above for both soccer and tennis.
• How much quantity of silica sand can be filled per square meter?
As said earlier, always depending on the density of the grass and its height, we install different quantities.
For tennis, we install 12 kg/sqm on very dense and short grass (11 mm) and for less dense tennis grass with higher pile we install sometimes 25-30 kg/sqm.
For soccer, the things are more clear, we install from 18-25 kg/sqm, depends on the grass height
• When can we change or replace silica sand for artificial grass?
The silica sand is considered as stabilizing infill and it’s always installed on the bottom of the
Grass for soccer, we install SBR rubber on the top. In that case it is very difficult to remove or
Reinstall the silica sand as we first have to remove the SBR granules…and that is quite expensive.
For tennis it is easier, as there is no SBR on the top, so we can remove some quantity of the
silica sand (mostly on the base line – as it gets harder due to the high traffic use). We remove the quantity of the silica sand with special brushes and then install the new quantity of silica sand ( normally, this can be made for tennis courts one per year, mostly end of the summer, before autumn comes and rain starts).In this procedure , we have to be careful with the grass pile as to many brushing can damage the pile.
• Does high quality of silica sand support ling life for the Turf?
Of course, when the grass of silica sand is completely and correctly filled with good quality, washed, dried
and rounded pure silica sand, it keeps the pile up and the damage( due to the hard use) is made only on the top of the grass. The grass that is filled with silica sand is actually protected. A good quality/quantity of the sand also helps the better water permeability.
• How much annual consumption of turf per year worldwide?
It is very difficult to say as there are many companies worldwide selling synthetic turf
in every corner of the world. Nobody knows it…
• What is most common methods used in spreading or filling silica sand into Turf?
The most common and the best way is installation with silica sand spreader, check the link
of the machine that I use http://www.redexim.com/redexim06.html
You install around 1 t of the silica sand in the box, connect it on the tractor, drive it on the
Field and it spreads the sand everywhere. Then you make the brushing so that the sand
Goes deep into the grass – more you brush, the sand goes deeper and deeper…
