Events that Create Connections and Memories!
Here, we also build people. At Ronveaux, events are not secondary; they are part of our culture.
Saint Eloi
A powerful and intimate moment: management speeches, meal, a large charity raffle via CIEL (the internal mutual aid fund), and an evening event that brings everyone together. The profits are used to support colleagues in times of hardship.
Family Day
A day to come with those who truly matter. BBQ, activities, children, laughter. Because behind every worker, there's a family.
Saint Nicholas
A truly magical moment for children: show, chosen gifts, photos, smiles, and a family atmosphere.
Lunches & food trucks
Several times a year, we simply get together to share a meal, without hierarchy, without fuss.
Safety Day
Training sessions, conferences, exchanges, visits to emblematic construction sites (RAAL La Louvière, Chertal…), discovery of the trades of other group subsidiaries. A time to learn, understand, and strengthen collective pride.

- here, you have a concrete and visible impact

A Culture That Is Felt, Not Displayed
Proud to be Ronveaux. Proud of what we build together.
At Ronveaux, our company culture isn't found in a PowerPoint. It's lived daily, on construction sites, in the factory, and in the offices.
Here, everyone retains their freedom, but no one is alone. Being Ronveaux means belonging to a home where people know each other, respect each other, and build for the long term:
- a family-like, warm, and direct culture
- a real proximity between teams and management
- a culture of performance, because staying a leader is earned
- an assumed authenticity: we eat together in the cafeteria, we speak openly, we move forward together
