The present invention relates to a method and device for producing moulded bricks made of hydraulically binding materials and with fibres, mats, bonded fabrics and wovens embedded therein, a formwork (1) composed of a frame (2) and a vertically movable base (3) being used. According to the invention, the base (3) is first adjusted to a height s below the top edge of the formwork, said height corresponding to the height of a layer of hydraulically binding material (5) and fibres, mats, bonded fabrics and wovens (6). The formwork (1) is then filled up to its upper edge with hydraulically binding material (5) by means of a mortar carriage (4). The fibres, mats, bonded fabrics and wovens are inserted into the fresh hydraulically binding material (5) in the desired orientation and the base (3) of the formwork (1) is subsequently lowered by a value corresponding to the height s. These steps are repeated until the desired height of the moulded brick is reached or until the base (3) of the formwork (1) may not be lowered further.
