High technology and environmental care based on experience

This is where the origins of Denys lie: laying water pipes, as founder Edouard Denys did from 1923 onwards. In those days it was a tremendous job: strong men hammered a thick, drenched cord of flax into the groove and then a ring of lead cord. This was all shuttered and set in steel-reinforced concrete.

Spurred on by us and by others, the technological know-how has continually grown since then, along with our familiarity with water.

Whether it concerns horizontal drilling underneath a riverbed or the sinking and anchoring of siphons on the bottom… Or whether it concerns the sinking of polygon shafts (e.g. to bore tunnels from there) or the construction of wastewater collectors or water treatment plants or water towers… in water we thrive.
