The device comprises a base (16) which acts as a support for a layer of resilient material (17) which is covered by a sheet of plastics material (18). On the latter there are disposed the perforated bricks (19) to be filled, with their perforations facing in a direction perpendicular to the layer (17, 18). There are provided a hopper (12) with at least one aperture (13) spaced from the upper surface of the bricks (19) in order to add the filling material (21), and a grid-type jig (29) which has raised perimeter edges (30), and a grid (31) which is provided on its lower side with a mat made of resilient material (32), which covers the gaps between the bricks, such as to prevent material from emerging from the perforations in the perforated bricks. There are also provided carriages which support the hopper, or a conveyor belt for the groups of bricks, such as to obtain relative displacement between the support base (16) and the hopper (12), in order to move from one row of perforations to be filled to another. <IMAGE>
