The utility model discloses a cladding stone material with the enhanced mechanical properties. The cladding stone material comprises a decoration stone board (1); and a mechanical property enhancing block (2) is adhered to the back face of the decoration stone board (1). A trimming opening (3) is arranged on the mechanical property enhancing block (2). After the decoration stone board (1) is effectively adhered to the mechanical property enhancing block (2), a through groove is formed between the trimming opening (3) and the decoration stone board (1); and the through groove is used for placing a hanging piece (4) of the cladding stone material. With the adoption of the cladding stone material provided by the utility model, the working efficiency can be improved; the quietness and the cleanliness of a field construction condition can be ensured; the security of the decoration engineering can be improved; the stone using thickness is reduced; and the natural stone resources can be saved.
