<p>The invention concerns a porous support-covering for playing fields, consisting of a rigid microporous coating (1) having a structure enabling it to maintain the surface covering (3) beneath which it is arranged permanently humid, said coating consisting of a mixture of microporous structural elements, bare filler elements, friction elements and binders ensuring proper cohesion of the assembly after the coating has been cast on the field infrastructure (2). The invention enables to produce shape-retaining playing fields highly resistant in time, unaffected by frost in most cases, preserving humidity, easy to maintain and remarkably comfortable for use in particular owing to its being dust-free.</p> |
