Method for manufacturing a hydrophobic element

A method of manufacturing an embossed hydrophobic covering element for construction or decoration for protecting a support surface from humidity or inclement weather, the method comprising:

• preparing a mixture of water and at least one organic material in a tank, the at least one organic material being insoluble in water;
• stirring the mixture so as to disperse the at least one organic material in suspension in water, the at least one organic material originating from a sustainably renewable resource;
• molding the prepared and stirred mixture by immersing a forming mold under vacuum inside the tank in order to form a molded element, the step of molding comprising:
• applying a molding cloth onto the portion of the mixture for a time of between 0.5 seconds and 10 seconds, the molding cloth carrying out a horizontal translation in a direction of the forming mold;
• drying and densifying the molded element under vacuum so as to obtain a dried and densified element;
• and
• fully impregnating the dried and densified element in a binder so as to form the hydrophobic covering element, the binder being an organic material having a softening temperature of between 50° C. and 80° C.
