Why Derbigum?

Offering sustainable waterproofing solutions, premium quality products, passing on its knowledge and know-how is a state of mind to build the foundations of a strong and authentic relationship with you - applicator, architect or owner of an industrial building or house - in the realisation of your flat roof project.


For more than 20 years, Derbigum has been developing innovative and sustainable solutions to protect the planet. What the generous earth took many years to develop, - bitumen, Derbigum wants to give back to it. We want to reduce the carbon footprint: by extending the life of the product as much as possible, recycling it at the end of its life and reusing it. Thanks to Derbigum's circular economy policy, more than 12,800 tones of CO2 have been avoided and 36 million liters of oil have been saved. (2010-2008 data)
