An elastic underlayer for floorings (1), for instance, floorings for sports facilities such as synthetic-grass coverings (1), comprises a first laminar structure (21, 22) and a second laminar structure (24, 25) that enclose between them pouches (22a) filled with granular elastic material (23). The structures (21, 22; 24, 25) in question comprise a layer of non-woven fabric (21, 24) coupled with a polyolefin layer (22, 24). The polyolefin layers (22, 24) enclose between them the pouches (22a), which preferably have a parallelepiped shape with a square base, with sides having a length of 20-60 mm, typically 45 mm, and a height of between 20 and 40 mm, typically 30 mm. The pouches (22a) are filled with granular elastic material (23), such as granules of recycled tyres having a size of between 0.5 and 7.0 mm. |
