Systems and methods for fabricating a retaining wall include an operation for making an untreated wall in the ground. This may be done by digging a trench in the ground and simultaneously mixing the ground in situ with a binder. Next may be a further operation for excavating a volume of ground adjacent to the untreated wall so as to uncover a surface of the untreated wall. Following that may be a further operation for treating the untreated wall during which a protective treatment substance comprising a polymer substance is applied to the surface that was uncovered in such a manner as to obtain a retaining wall of a thickness that is substantially equal to the thickness of the untreated wall.
