Input and output materials


Inputs such as sand, cement, lime, aggregates, superplasticizers, retarders, etc., are stored in individual silos or tanks or in chemical tanks, or if necessary in storage areas. Silos are primarily filled from silo trucks, which can make the fill using air pressure from the individual silo truck or pressure generated by the line. For restricting or inspecting the largest factions of the inputs into the silos, a sorter with the sieve currently set at a mesh of 3.15 mm can be used. For inputs into big-bags (large volumes sacks), the silos are filled via a pressurized container (“Blue Onion”), with the material blown into the individual silos. These pressure containers can also be used for the temporary storage of material. Chemical storage tanks are filled from bags located on a mobile trolley.

Capacity of the silos (average for 1 silo)

60 m3

Product storage capacity (average for 1 container)

20 m3

Number of chemical containers


Capacity of chemical containers (average for 1 container)

All inputs undergo laboratory checks upon arrival, particularly for humidity, correct granulometric curve, age, hardness, etc., as needed.


Products are packed into valve bags on three bagging devices and these bags are then transported to two palletizers. Before being stacked on pallets, the bags are inscribed with an Ink-Jet marker with a high quality imprint thanks to piezo electric deflection ink. The bags are arranged by the palletizers and wrapped with self-shrinking film before being dispatched to the warehouse.

Products can also be packed in large volume big-bags.
