SAND RESEARCH & DEVELOPMENT
Not all sand is the same!
Sand comes in a variety of grain sizes, from 0,063 to 2,0 mm
|We distinguish between:||fine sands
||( IS / FSa) 0,063 - 0,2 mm|
||( Ms/ MSa) 0,2 - 0,063 mm|
|coarse sands||( Gs/ CSa) 0,63 - 2,00 mm|
If the grain size is above 2.00 mm then this is considered gravel, which is not suitable for riding arenas!
The grain structure of a sand is also of elementary importance
Due to the nature of its creation there can be a number of different types of grain. There can be round, flat or cuboid grains of sand, all of which are very different in their characteristics as well as in the way they can be used.
The colour of the sand
The colour of the sand is also an important factor.
Depending on the creation and origin of the sand the colours can vary to a large degree, from snow white to golden yellow to dark grey and black.
The hardness level
The hardness level of a sand is very important when deciding what it is to be used for!
There are sands that are characterised by very soft grains and which are ground down by certain surface wear, such as by (hoof strike) pressure. Furthermore, there are sands that are characterised by grains that are so extremely hard or sharp-cornered that they rub open the fetlock area and wear out the horse shoes very quickly. The grading of the hardness level of sands is between 1.0 and 10.0.
In addition, riding surfaces with hard sands freeze quicker, as the the water moves more quickly around the grain and freezes immediately at minus temperatures (even at -1 °C). In comparison a slightly softer grain, which can absorb some water into its core, does not freeze immediately.
The topic of sand is quite complex....
that is is imperative to produce the correct sand mixture for the respective disciplines of equestrian sport, as well as to view the environmental conditions at the location in question in great detail.
The surface layer should be hard-wearing yet yielding. It should provide an appropriate shear strength (interleaving) as well as certain degree of elasticity and good hydraulic permeability, and much more.
A sand should work well optically (colour) on a riding arena or riding hall.
It all comes down to the sand mixture!
Our „BOver –equestrian sand“ is the unique basic foundation for all kind of equestrian activities and is the the substructure of our indoor and outdoor premium-surfaces.
