The concrete mixing plant is a hive of activity! An impressive mixing plant with 3 rows of high silos and an office building forms the centre. A passageway allows lorries to be loaded quickly. The sand bunker pockets are subdivided for different types of sand and gravel and sand in 3 different colours is also included for shaping the sand bays. A crane device and a gravel loading silo with conveyor belt (without function) are also included and complete the scenery.
