Abstract
A substrate for floorings, such as synthetic grass turf includes: a pad made of a first heat-meltable material, a stabilizing mesh made of a second heat-meltable material, and a connection layer set between said pad and the mesh. The connection layer includes a third heat-meltable material with a melting point lower than the melting point of the first and of the second heat-meltable materials. The connection layer is a discontinuous layer with a granular structure, so that the substrate is permeable to liquids in order to enable, for example, draining-off of rainwater.
