Dekkers was founded in 1945 with its focus on road works. With branches in Hoboken, Brussels and Ghent, Dekkers underwent a huge breakthrough thanks to the metro tunnels. Dekkers waterproofed more than 95% of the Brussels metro tunnels.
Since 2000, Dekkers' shares were taken up by the Tectum Group, which brought renewed dynamics: complete renovations of buildings, new recruitment and a customized strategy.
Group Biesmans experienced exceptionally strong growth in a very short period. A new headquarters was built with offices and warehouses on the Vaartstraat in Genk.
Cham International (later Group Biesmans) was taken over, and remains the family holding today.
The establishment of the company DAK took care of our first steps into the roofing market in Flemish Brabant.

Growth came like a fast current and the company gained a significant position in the Belgian roofing sector.
