Claims10
A method of making an equestrian surface comprising providing a layer of sand and blending stone fibres into the sand, wherein the proportion of fibres, based on weight of sand, is at least 0.2 weight % and no more than 20 weight %;
- wherein the fibres have length at least 2000 microns to 5000 microns and are in the form of a granulate comprising flocks of entangled fibres.
A method of modifying a riding surface formed of sand by blending stone fibres with the sand;
- wherein the proportion of fibres, based on weight of sand, is at least 0.2 weight % and not more than 20 weight %;
- wherein the fibres have length at least 2000 microns to 5000 microns and are in the form of a granulate comprising flocks of entangled fibres;
- whereby the cohesivity of the riding surface is improved by modifying the riding surface;
- wherein the fibres are bio-soluble and have a dissolution rate at pH about 4.5 of at least 25 nm per day.
