Abstract
A method for producing a hydrophobic element is disclosed and includes the following steps: a) preparing a mixture of water and an organic material from sustainably renewable resources, b) moulding the mixture prepared in step a) to obtain a moulded element, c) drying and densifying the moulded element obtained in step b) to obtain a dried and densified element-, and d) impregnating to the core the dried and densified element obtained in step c) with a binder composed of organic materials from sustainably renewable resources. A covering hydrophobic element containing more than 90%, and preferably more than 99%, of an organic material from sustainably renewable resources is also disclosed.

Method for manufacturing a hydrophobic covering element, characterised in that it comprises the following steps:
- a) preparation of a mixture of water and of organic material coming from sustainably renewable resources;
- b) moulding of the mixture prepared in step a) in order to obtain a moulded element,
- c) drying and densification of the moulded element obtained in step b) in order to obtain a dried and densified element,
- d) full impregnation of the dried and densified element obtained in step c), in a binder composed of organic materials coming from the resources that are sustainably renewable in order to obtain a hydrophobic covering element.
Hydrophobic element for covering at least a portion of a surface, such as a wall and/or a ceiling and/or a surface in contact with the outside, said element having a developable or non-developable shape and comprising a back in contact with said surface and a visible front, characterised in that it comprises more than 90%, and preferably more than 99%, organic material coming from sustainably renewable resources.
