Depret NV had its origins as a towage company at the end of the 19th century. In 1929, ‘Depret Frères’ set up a new company in Ghent. Their activities were concentrated on the salvage of wrecks and dredging work. At the end of the 1970s the headquarters of the company was relocated to the port at Zeebrugge, which by then had developed into a major trading centre. Over the course of the years, Depret has also come to focus on construction and civil engineering works in East and West Flanders.
On 23 August 1948 NV P. Roegiers & Co. was founded by Pierre Roegiers. For the first 20 years, its activities were confined to hydraulic engineering; more specifically, maintenance and repair works in the port of Antwerp and along the River Schelde. From the 1970s onwards the company also became a leading name in the fields of building construction and civil engineering, whilst still maintaining its excellent reputation in the field of hydraulic engineering.
TWT SA was founded on 1 April 1993. Six months later the company opened new premises at Seilles (Andenne) on the River Maas, where it is still located. Initially, its activities were confined to hydraulic engineering; more specifically, maintenance and repair works. Today, TWT is also active in construction, civil engineering and restoration work.
Since a management buy-out in 1989, all these companies have become subsidiaries of the ARTES-GROUP.
As a result of an increasing demand for a partner that could not only undertake construction work, but could also offer added value in respect of the design, financing, maintenance and even exploitation of a project, the decision was taken in 2007 to set up ARTES-PROJECTS, for the specific purpose of further developing PPS structures and immoveable property promotions.
In 2008 the ARTES-PREFAB subsidiary was set up with a prefabricated concrete unit and an iron unit for the supply of rebar to the Depret, Roegiers and TWT subsidiaries.
In 2010 the Artes-Group acquired a participation in REBO (Renewable Energy Base Ostend). REBO was set up to build and exploit new mooring facilities on a 10 hectare site in the front harbour at Ostend for use in the construction and maintenance of wind turbine parks at sea.
In 2011 the Artes-Group took over NV Woudenberg, founded in Bruges in 1982. This new acquisition serves as the restoration arm of the group, being specialised in the renovation of both listed and non-listed monuments and buildings.
This year the Artes-Group also became a co-shareholder in dotOcean, a high-tech company founded in Bruges in 2008 and specialised in innovative underwater instruments and sensors for the maritime and offshore industries.
