THE EFFECTS OF FOOTING
It is useful to compare the physical characteristics of different surfaces in relation to their effect on the horse's stride. Hard surfaces (concrete, asphalt, hard soil) have a high impact resistance and a high shear resistance. Consequently, the limbs are subjected to considerable concussion, and the toe is unable to penetrate the surface, which produces high loads in the navicular region in the terminal stance phase.
Sand has a somewhat lower impact resistance than hard soil, combined with a low shear resistance which allows the toe to penetrate deeply. However, deep sand tends to give way resulting in a loss of traction. Since horses must use a greater muscular effort to overcome the tendency of the sand to give way, the working heart rate will be up to 50% higher on deep sand. This is why sand is so tiring for the horse to work on.
Amendments, such as textiles and fibers, are added to sand to improve the properties as a riding surface. GGT-Footing, a shredded textile, stabilizes the sand particles - this mimics the effect of the rooting system of turf, which has a stabilizing effect on the surrounding soil particles.
Our products give more resilience, reduce the amount of packing and help to hold moisture in the surface, which leads to reduced dust.
