Abstract
A flooring, for example for pitches for soccer, five-a-side football, American football, rugby, etc. which includes a polyolefin-based impermeable layer and an elastic mattress laid on top of the impermeable layer which includes a core layer having an agglomerate granular material and an envelope that envelops the core layer. A structure of synthetic-grass covering is laid on top of the elastic mattress and includes a sheetlike substrate with a plurality of filiform formations extending from the substrate to simulate the grassy sward of natural turf, as well as a particulate filling material or infill dispersed between the filiform formations to maintain the filiform formations themselves in a substantially upright condition. The flooring is suited to being laid directly on the previously flattened laying foundation so as to bestow a camber thereon to facilitate draining, such as a pitched camber.
