In the world of careers, where efficiency and precision are essential, automation is becoming a key solution to meet operational challenges. This is exactly what the Carrières d'Étavaux, located in Calvados, in Normandy, have experienced with the recent installation of a Synaxe terminal. A look back at this transformation through the testimony of Paul Koener, quarry operator and site director.
A historic site in full modernization
The Quarries d'Étavaux, which were created in the years 1920-1930, produce aggregates for the industrial, public works (TP), and materials trading sectors. In addition to this main activity, the site has diversified with the manufacture of construction products, such as agglomerated blocks, floors and ready-to-use concrete (BPE).
Faced with the retirement of an employee responsible for the changeover, the team had to rethink its weighing and flow management processes. Their solution? Integrate an automated weighing system proposed by Synaxe, an innovative terminal designed to streamline incoming and outgoing material flows.

A solution that transforms daily operations
The Synaxe terminal was installed five months ago now and quickly proved its effectiveness. According to Paul Koener, the benefits are being felt on several levels:
- Saving time and redeploying resources
- The operator, previously dedicated exclusively to managing the scale, can now focus on other essential tasks. This change improves the overall productivity of the site.
- Improving traceability
- Thanks to the automated system, material flows — whether they are inputs (inert materials) or outputs (aggregates) — are precisely monitored. It also makes it easier to manage customer returns.
- Increased customer satisfaction
- Customers, especially truck drivers, use the terminal on a daily basis and benefit from a seamless experience. This autonomy is welcomed by users.
Concrete and measurable results
The initial objective was ambitious: to automate 80% of incoming flows to manage them directly via the terminal. Today, this objective has been achieved, demonstrating the effectiveness and reliability of the solution implemented.
The feedback is unanimously positive, whether from internal operators or external customers. In addition to responding to an operational problem, the Synaxe terminal has brought real added value by optimizing time, resources and customer satisfaction.
Why choose an automation terminal?
The experience of Les Carrières d'Étavaux perfectly illustrates the benefits that an automation system like Synaxe can bring in the quarry sector:
- Reduced labor costs.
- Optimization of logistics processes.
- Increased reliability thanks to impeccable traceability.
By investing in innovative solutions, businesses can not only respond to immediate challenges (such as replacing an employee), but also prepare for sustainable and efficient management of their activities.
