Franki was the first foundation company to use the diaphragm wall technique in Belgium in 1962. Franki Foundations wants to stay in the frontline of development by following up closely and fully mastering the latest technological evolutions and by investing in the most innovative, high-quality and high-performance machinery. Franki Foundations has worked together with the Dutch guideline committee CUR (“Civieltechnisch Centrum Uitvoering Research en Regelgeving”), a cooperative body in which the main actors involved in civil engineering do research and formulate design rules and standards - for the establishment of a reference textbook with new guidelines for the execution of diaphragm walls.
