Derbigum: a solid and innovative partner

An experienced partner

…you can rely on

Derbigum/Imperbel was founded in 1932. Over a time span of more than 80 years, the company has grown to become a well-respected global group, specialised in waterproofing and energy management.

Derbigum has one production plant in the United States and two in Belgium. Today the company employs about 400 people worldwide and has a consolidated net turnover of over 120 million Euros.

Your best investment

45 years ready for you

Studies by independent agencies show that Derbigum roofing has a proven lifespan of 30 years and an expected lifespan of more than 35 and 40 years. At this moment there are roofs of 45 years that still prove their functionality every day.

Other waterproofing solutions have a lifespan of 10 to 20 years: these need to be replaced and a reinvestment for the renewal of your roof is necessary. What’s more, these are less resistant and result in higher maintenance and repair costs. Choosing Derbigum means choosing the most profitable long-term investment.

Since the establishment of the company, Derbigum has convinced many roofing specialists of the quality of its products.

  • The finest components and the noblest polymers give the products their impeccable quality.
