Synthetic turf and natural turf are arranged on a substantially elastic permeable substrate, and the elastic substrate is configured so that the root of the natural turf can penetrate to the growth layer arranged in the lower position, Synthetic turf and natural turf that can absorb energy from impact generated on the surface in order to avoid compression of the root growth layer arranged in the lower position. a) seeding natural turf seeds on a layer of filled soil placed on a base supporting synthetic turf fibers and on a substantially elastic permeable substrate； and b) natural turf fibers on synthetic turf fibers. It grows until it reaches a height higher than the height of the natural turf, and the root of the natural turf can penetrate the base supporting the fibers of the synthetic turf so as to reach the growth layer located in the lower position and penetrate the elastic substrate And c) a height comprised between 0.015 m and 0.040 m of natural turf, particularly depending on the application given to the surface, in order to maintain a natural turf height at least equal to the fibers of the synthetic turf Mowing natural turf grass in order to maintain.合成由来の芝及び天然由来の芝が実質的に弾性の透過性基板上に配置され、弾性基板は天然芝の根が下方位置に配置された生育層まで貫通できるように構成され、弾性基板は下方位置に配置された根の生育層の圧縮を回避するために表面に発生した衝撃によるエネルギーを吸収できる合成由来の芝及び天然由来の芝。ａ）合成由来の芝の繊維を支持するベース上及び実質的に弾性の透過性基板上に配置された充填土の層に天然芝の種を播く段階と、ｂ）天然芝を合成芝の繊維の高さ以上の高さに達するまで成長させる段階であって、天然芝の根は下方位置に配置された生育層に達するように合成芝の繊維を支持するベースを貫通でき且つ弾性基板を貫通できる段階と、ｃ）少なくとも合成芝の繊維と等しい天然芝の高さを維持するために、特に表面に与えられる用途に応じて天然芝を０．０１５ｍと０．０４０ｍの間に含まれる高さに維持するために、天然芝の草を刈る段階とを含む方法。
