Welcome @ DenysDenys is a multidisciplinary group specialised in water, energy, mobility, architecture, restoration and special techniques. Because of this unique diversification, Denys is a preferred partner for complex building projects and infrastructure work, in Europe, Africa, the Middle East, Canada and South America.
Denys is your dream partner for constructing extraordinary buildings. Our ‘design, construction and maintenance’ approach offers an ideal solution tailored to our clients. The multidisciplinary structure of our organisation also ensures efficient realisation.projecten
Mobility is a major challenge in today’s world. Denys’ unique experience in areas such as earthworks, tunnelling and stabilisation, together with everyday activities involving road and rail infrastructure allow us to invest fully in new technologies to make our works more efficient and minimise the disruption to traffic.projecten
Denys began laying major water mains in 1923. Since then, Denys has grown into a leading builder of water, gas and oil pipelines. With exceptional technological know-how and an impressive fleet of machines, Denys currently builds pipelines in Europe, Africa and the Middle East. In future, Denys will also be able to make a difference in other regions of the world.projecten
Restoration & Renovation
Denys is highly passionate about restoration and renovation. This discipline breathes new life into our magnificent heritage, incorporating the power of the here and now. What started for Denys as restoration using specialist injection techniques has grown into a versatile restoration department with many highly qualified specialists. Denys bridges the gap between tradition and high-tech. We employ the most innovative and sustainable building techniques with the greatest respect for the original character.
We are member of the department "General contractors Heritage restoration", established within the Federation of General Construction Companies (FABA) of the Construction Confederation (www.erfgoedrestauratie.be).
Denys is a past master of boring tunnels in soils with varying geology, under rivers or global cities using unique tunnelling machines. Our highly driven drilling specialists work in many European and North African soils. With great success! Through our in-depth knowledge of micro- and mid-size tunnelling (just about the most difficult underground discipline) Denys is also the right partner for larger diameters.projecten
From Belgium to deepest Africa, Denys not only lays (drinking) water pipes but also constructs entire water supply systems. From pumping stations and water treatment plants to building water towers.projecten
With respect for the highest quality standards and impressive expertise and experience, Denys also provides exceptional “water works” such as the design, production, construction and renovation of the most complex cooling water pipes for power plants such as nuclear power plants.projecten
Relying on an experience of almost 100 years in linear projects over large distances, such as pipeline construction and rail works, Denys has become a specialist in the installation of underground high voltage cables since the last decade. High voltage cables, that used to be built as overhead power lines and disgraced the landscape with their high pylons, are now being built underground using innovative techniques and respecting all regulations regarding safety and environment. Several highly satisfied clients keep on relying on Denys’ professionals offering total solutions.projecten
The development of modern heating networks is a crucial part of making our energy supplies sustainable. Denys designs and builds these heating networks, working on behalf of government authorities, energy companies and industrial customers. By doing so, we are able to control every aspect of the process: problematic substrates, difficult access ways, tight deadlines, etc. We have built up a great deal of experience in this area over recent years and our extensive expertise and knowledge about working with pipes, controlled drilling and microtunnels stands us in good stead.projecten
The rail network is expanding all the time and Denys is involved in its growth. We have the people, expertise and machines needed to build railways, metro lines and tram tracks, including any civil engineering works required, such as renovating old tunnels, drilling new tunnels and constructing bridges and station buildings. We are known for our efficiency, flawless organisational skills and the smart use of innovative methods.projecten
Special foundation & injection techniques
Special techniques make life easier, which is why Denys is so well qualified in this area. We specialise in ground stabilisation (nailed walls, compensation grouting, facing and/or underpinning buildings) and concrete repairs and/or concrete spraying of artworks and civil engineering works and tunnels. To do so, we use techniques such as jet-grouting, various low-pressure injection techniques, deep-mixing, micro-piles, ground anchors and shotcrete.projecten
Denys strives hard for innovation and builds determinedly for the future by inventing and developing new forms of mobility : Underground Container Mover, Tube Cargo Express, TZH (low disruption excavation). We are also totally focused on developing new techniques to improve the daily working conditions of our employees and make them safer, as well as raising our quality to excellence : WallSlotrobot, automatic sandblasting, Friex welding, WRIST, 3D carving robot.projecten
IN DE KIJKER
Porthos - Denys helps the Netherlands to achieve its climate objectives
We are proud to inform you that Denys was selected to build the Porthos project, which was developed by the Port of Rotterdam Authority, Gasunie and Energiebeheer Nederland to contribute to achieving the Dutch climate objectives.
We were specifically awarded the design and construction of the 30 km 42” CO2 transport pipeline in the port area.
This project fits perfectly into our sustainability ambitions as a multidisciplinary construction group with many years of experience in the study, design and realisation of pipelines and underground transport infrastructure.
We are therefore proud to be able to take on this challenge with the Porthos team and to gain the confidence to help realise this important step in achieving the Dutch climate objectives.
