1. Method of making composite building elements forming for instant parallellepipedic blocks or parpens and of the type consisting in filling at least one mould (2) with at least two materials of differing compositions introduced successively into this mould so as to obtain after stripping a block with two layers or stratums of different materials, characterized in that before inserting a first material into the mould, one disposes across and inside of the moulding space a plate or the like (4) onto which this material falls so as to carry out the moulding of a layer of the block between this plate (4) and the open top portion (3) of the mould (2) and then the said plate is retracted from the inner moulding space to cause the said layer to move down through gravity to the bottom (2b) of the mould, whereupon another material is inserted into the remaining space (2a) of the mould to form another moulded layer between the upper portion of the first layer and the mould. |
