Resarch and Development

Research & Development is a major component of BdN’s innovation strategy. We invest in R&D to modernise our production processes and develop new products adapted to the construction market while respecting the environment.

The missions of the R&D pole:
Continuous improvement of the manufacturing processes and of the quality of existing products

  • Development of innovative products that meet customer requirements
  • Study of new fields of application that highlight technologies and products

Industrialization projects

The research and development of new manufacturing techniques, always more modern and at the cutting edge of technology, allow us to improve the productivity, quality, repeatability, and traceability of our productions. All of those important factors allows the continuous improvement of our productions: knowing what we do enables us to consistently repeat it better.

Over the last 15 years, the two production sites at Lomme and Templeuve have been thoroughly modernised at all stages of production: from the extraction of raw materials to the quarry, including the preparation of clay mixtures, the moulding of bricks, drying, firing and palletising of products before they are shipped.
