ABSTRACT OF THE DISCLOSURE A sports ground covering has a lower cushioning layer, an upper wear-resistant layer, and an intermediate reinforcing iron netting. Both the layers contain rubber chips produced from old vehicle tires. The lower cushioning layer contains interspersed spherical expanded clay, which gives the layer resilience and makes it independent of atmospheric humidity during production.
