The invention relates to civil engineering. It relates to, in particular, a method of producing a moulded wall made of hard earth, this moulded wall being formed by one or more successive constituent panels, according to which: a. an excavation of desired depth, length and width is made, b. this excavation is filled with a hardening compound, c. after sufficient setting of the hardening compound, if the wall is formed from several panels, a new excavation N is carried out following the preceding one, d. this new excavation is filled with hardening compound and, e. steps c and d are repeated as often as necessary, the said method being characterised in that each excavation is the result of a plurality of intersecting successive parallel circular elementary borings 1, 2...n.
