Sand is a cornerstone ingredient in all construction and maintenance materials for both natural and artificial playing surfaces.
Whether mixed with an organic amendment to produce topdressings, rootzones and divot mixes, or used on its own as a synthetic carpet infill or beach sport surface, sand plays a vitally important role in a playing surface's performance, appearance and longevity.
Ruffords Technical Manager, Mick Higgins, explains what sand is and introduces some basic considerations
Sand comes in many different forms, all of varying quality with a range of properties and physical characteristics, so the challenge is to select the right one for your project.
What is sand and where does it come from?
Sand is an inorganic granular mineral composed of individual particles or grains formed by the weathering and erosion of rock.
These small, finely divided fragments of rock will vary in chemical composition depending upon the source and condition of the parent rock from which they were derived.
As far as the UK is concerned, sand refers to a material which has a grain size distribution between 0.063mm and 2.0mm. However, there are some countries, including the USA, who categorise sand particles as those having a diameter between 0.053mm and 2.0mm.
In the UK all particles less than 0.063mm but greater than 0.002mm are classed as silt, with particles less than 0.002mm categorised as clay. Any particles greater than 2.0mm are categorised as gravel.
It is important to remember that any particle between 0.063mm and 2.0mm would be classed as sand, including material with very high calcium content (calcareous sands).

Whilst this process would reduce the silt and clay content, it would not sort the grains or improve the particle size distribution. Whilst a simple form of processing may be acceptable for some basic building/construction applications, it would not be
