Our Slags


Slag is mainly used for embankments, as a fill for road foundations, and for asphalt paved parking lots. Expanding uses for slag requires searching for other possible uses, such as filtering wastewater in treatment plants.



Slag is produced at the same time as steel in an electric furnace. Molten slag is at a temperature of about 1650 degrees, after which it is separated from the steel and then cooled. It is then deferrized, crushed and screened based on desired particle size.


The quality of slag is monitored through the manufacture process until it is transformed into a ready-to-use product. Samples are taken regularly for laboratory analysis and quality verification. A quality data sheet based on these controls is issued to users of the slag. Analysis and compliance certificates are issued upon request. The mechanical properties of the material are also tested in the laboratory before it is used in roadworks, platforms, parking lots. The entire slag production process is managed under Quality Assurance.



Slag is easy to implement, it compacts easily and does not deform. It remains stable with advantageous density, and does not sink under a heavy load. Its high mechanical resistance and perfect resistance to abrasion make it ideal for integration into asphalt paving. Many projects have already been carried out successfully, attesting to the great efficiency of slag.



Slag helps to safeguard natural resources by replacing gravel, for example. Proximity to the source of supply also reduces transport and CO2 emissions. Slag is a material that fits perfectly into a sustainable development rationale.
