Environmental restoration has gained importance in all executions of civil works that are carried out within a space with a natural environment. The main actions are: replanting of native species, hydro-sowing and hydro-blanketing. Hydroseeding and hydro-blanketing are two techniques that allow us to project a mixture composed of seeds, fertilizer, stabilizer and fixer that allows seeds to germinate on land of very poor quality, even, almost vertical slopes and hard or rocky composition. On the other hand, the replanting of autochthonous species, as its name suggests, consists of replanting native species from a place that has been spoiled by the passage of time, atmospheric phenomena, human causes or damage to works.
