History of Derbigum
DERBIGUM has 90 years of experience in the roofing industry. The story begins in 1932 with the creation of Imperbel, a family business producing waterproofing membranes located in Huizingen, south of Brussels.

1932
The founder members Francis Blake and Agnan de Goussencourt start the production of a waterproofing paste for roofs. The family company Imperbel is born.

1978
In partnership with other European partners, Imperbel starts a Derbigum plant in Perwez. This production unit aims at optimizing and industrializing the membrane and its production. Four years later, the company acquires a controlling share in the factory.

2010
In 2010 Derbigum takes its recycling policy a step further. The company develops together with its distributors a unique system for cutting waste and for roof waste.

2012
Derbigum integrates synthetic membranes in their range. Thanks to high polymer EVA/VC terpolymer roofing membranes, new perspectives for the further growth of Derbigum in Europe are visible.

2017
On 16 February, the Board of Directors approved the investment of € 4.5 million for a new production line in Perwez. This investment fits well with the group’s objective to focus on the development of the bitumen business, both in Europe and in export markets. The new line will also enable the Group to respond more effectively to customer and market expectations.

2019
Derbigum is investing in the construction of a new, more efficient and modern production line. It also continues to invest in the circular economy with the construction of a 3rd recycling unit.
