In 1892 Dr Carl Dorken and Ewald Dorken founded the Dorken company.  When Dorken was first founded it was for the production of lacquers, paints and anti-corrosion paints.  Over the next 10 years Dr Carl Dorken developed methods for manufacturing these paints.  Under the EBRUIT brand these speciality paints became a leading brand.


Dorken commenced production of roofing membranes for railway carriages.  This was the basis for the company’s future involvement in composite construction sheets.

In 1929 Ewald Dorken AG is founded.


Dorken begin production of reinforced composite sheets.  The development of DELTA-FOL SPF starts the Company’s European Success in Synthetic roofing underlayments under the 3rd generation of Dorken leadership. This lead to the production of air-gap membranes for foundation moisture protection (Delta MS) was launched.  The brown dimple sheet with orange stripe quickly became a well known company trademark.

Following this:

Delta Terraxx, an innovative, durable high-performance drainage and protection sheet for perimeter insulation and various substrates are launched.
