Our Concrefy Core Values

These values show the heart of our team and culture and lead us to make the difference for our stakeholders.


Concrefy has a rich history dating back to 1978, when Ing. J.J. Stapels founded the concrete consultancy firm “Betontechnisch Adviesbureau Stapels” (BAS) in Oostrum, The Netherlands.
It was not until the company’s acquisition by Ir. A.J.E.J. van Casteren in 1994 that the consultancy firm initiated its considerable modern development.
In 1999 this was signified by its transformation into the “Instituut voor Betontechnologie, Advies en Schade-expertise” (BAS) and the establishment of a modern accredited laboratory in Venray, The Netherlands.

The next step in the evolution of the company occurred in 2007, when the largest and most modern concrete laboratory of the Netherlands “B|A|S Research & Technology” was moved to Venlo.

Since its foundation B|A|S has rapidly developed into a renowned international concrete engineering firm. The company develops unique value engineering concepts combining concrete technology and digital techniques.

As of July 2016 the company has become a part of the Doka family, focussing on further international growth. In 2018 we say goodbye to B|A|S and get a nieuw brand : Concrefy – fresh thinking for construction.
