History

Concrefy’s roots date back to 1978, when Ing. J.J. Stapels founded the concrete consultancy firm Betontechnisch Adviesbureau Stapels (BAS) in Oostrum, the Netherlands. From the beginning, the company focused on concrete expertise, quality and practical application.

In 1994, following the acquisition by Ir. A.J.E.J. van Casteren, the organisation entered a new phase of professional development. In 1999, this resulted in the establishment of an accredited laboratory in Venray and the transformation into the Instituut voor Betontechnologie, Advies en Schade-expertise (BAS).

In 2007, the laboratory activities were further expanded with the relocation to Venlo, where BIAS Research & Technology developed into one of the most modern concrete laboratories in the Netherlands.

In July 2016, the company joined the Doka family and later became part of Umdasch Group Ventures. In 2018, BIAS continued under a new name: Concrefy.

Building on its technical expertise, Concrefy has also contributed to the development of digital solutions for the construction industry. As of 1 February 2026, these digital solutions have been integrated into Doka’s digital solutions portfolio and are marketed by Doka.

Today, Concrefy operates as an independent consultancy and laboratory partner for the construction industry, with decades of experience in concrete technology, testing and technical expertise.
