1987 saw the commissioning of the first ready-mixed mortar plant (FMA, in German) of the Wietersdorf. The investment made here was some 35 million Austrian schillings (the equivalent of 2.5 million euros) and involved a 40-metre-high mixing tower. Originally, 37 silos (1,540cm) were at our disposal where binders, aggregates and additives were stored. An extension by 12 silos (600cm) was envisaged right from the beginning. The materials were transported to the mixer via dosing screws to up to four weighing units. Light aggregates, such as perlites or polystyrol were added with the help of separate volumetric dosage facilities. The ready-mixed material was then either blown directly into the transport silos or transported to two bagging machines via a closed conveyor belt system. After being filled, the bags were taken over the transport route to a fully automatic palleting facility, and from there via forklifts to the dispatch warehouse.
