About Denys

Denys is an independent Belgian construction group employing around 1800 people worldwide.

Our growth model is based on three pillars: diversification, innovation and internationalization. We don’t innovate in one speciality, but as a total business in several disciplines: water, energy, mobility, infrastructure, refurbishment, civil engineering, special techniques and other specialised building techniques.

Denys strongly believes in the future of the energy transition and underground infrastructure : solutions for mobility problems, logistics transport, water storage, CO2 capture and storage, hydrogen pipelines, heating networks, underground high-voltage cables and cooling water systems for the nuclear sector.

In addition, we are not shy of forming constructive partnerships in public-private ventures, where the responsibility of the contractor is much greater. Denys has also been active for decades in the private market as a benchmark for reliability.

The Denys Group, a preferred partner for the most complex building projects and infrastructure works.
