Our history
The history of Tectum Group began in 1981 with the establishment of VHB, a company that was later renamed Dekkers Genk. The founders, Jean Biesmans and Lydie Schols, initially focused on road works and later expanded into roofing materials.
In 1988, CPE SA was established, a wholesaler of roofing materials and an official distributor of Firestone Building Products in Belgium.
In 1990, Tectum Group bought Cham International (later known as Group Biesmans), which became the family holding company.
The company expanded into Flemish Brabant in 1994 with the establishment of DAK nv, which focused on both flat and pitched roofs. This led to a strong growth of the company, giving us an important place in the Belgian roofing world.
Group Biesmans is experiencing strong growth in a very short period of time. Consequently, a new headquarters with offices and warehouses is being built in the Vaartstraat in Genk.
In 2000, Tectum Group acquired Dekkers nv, which initially focused on road works, but later became involved in the waterproofing of Brussels subways. More than 95% of Brussels subways were waterproofed by Dekkers. With the acquisition came a renewed dynamic, with Tectum Group focusing on complete building renovations, new acquisitions and an adapted strategy.
In 2002, Tectum Group introduced the new concept Roofcomfort nv, where owners and tenants of buildings with a patrimony spread all over the country could go for study, budgeting, prevention, intervention, maintenance and renovation of roofs.
Tectum Group expanded into Poland in 2005 with the establishment of Dekkers Polska Sp.zo.o. The first international branch of Tectum Group.
In 2007, the company acquired Herreman & Lippens of Melle. This allowed it to expand its activities into pitched roofs and ventilated facades. The company is now known as Tectum Constructors.
Tectum Aluminium with a branch in Hoboken was founded in 2010. In addition to roofs and facades, the group now offers balustrades.
In 2011, Group Biesmans changed its name to Tectum Group.
In 2013, Protectum was founded specializing in collective fall protection and liquid waterproofing.
In 2014, Dekkers Sud was founded in Charleroi, expanding Tectum Group's roofing activities into Wallonia.
Tectum Group opts for strong branding and communicates under: Tectum Dekkers, Tectum Aluminium, Tectum Roofcomfort and Tectum Constructors. With a network of 22 companies, Tectum Group employs 420 people every day.
Together with MSQ, Tectum Group participates in Hollanddak Group B.V. of Waalwijk (NL). Hollanddak is one of the largest roofing companies in the Netherlands. They specialize in installing plastic membranes for sealing utility buildings, distribution centers and large roof areas of other buildings. This makes Hollanddak a strong addition to our contractor activities not only geographically, but also in terms of expertise.
As the first roofing company in Belgium, Tectum Dekkers obtained the Class 8 certificate. This meant that from then on Tectum Group was allowed to take on roofing jobs of more than 5.33 million euros.
In 2021, we may receive the award for Limburg Entrepreneur of the Year. The jury was particularly charmed by the great course we have already taken and our high ambitions towards the future.
In 2022, we will win the Limburg HR Award from Voka thanks to our strong HR policy with a clear focus on training and coaching.
At the end of 2022, Tectum Group is increasing its expertise by welcoming the Roof & Facade division of contracting company SIX into the group. It also fits in with the strategy of focusing on renovation with several branches in Belgium, with a focus on renewal construction and circularity. Read more.
