Specialist in high performance deep foundation techniques

This soil-formed foundation pile, developed around 1900 by Edgard Frankignoul, underlies the international success of the Franki Foundations Group, part of BESIX. Subsidiary Franki Grondtechnieken serves the Dutch market. 

"Frankignoul was a true pioneer," says director Jan-Wim Verhoeff of Franki Grondtechnieken. "In addition to developing the Franki pile, he was the first to implement new foundation systems such as bored piles and diaphragm walls. Already in 1940 he was active on almost all continents of the world. Now, as a group, we have 110 years of global experience in deep foundations. We specialize in pile foundations, retaining walls, soil improvement, injection works and coordination of related activities."

The power of the group

As part of the Franki Foundations Group - with branches in Belgium, France, England and the Netherlands - Franki Grondtechnieken combines the best of both worlds. "We have our own market, but can also use the people and machinery from within the group," Verhoeff explains. "Also, our people are deployed abroad. We have crews working year-round on specialized ground techniques, such as diaphragm walls or large diameter bored piles. Our large market area also allows us to ensure continuity in these types of techniques. This further helps us to optimize execution processes."

Complex works

Whether it is a foundation in an operational petrochemical plant, a parking garage in the middle of the city or a large-scale infrastructure project with tunnels and bridges; these are the complex works in which Franki Grondtechnieken demonstrates its added value. Verhoeff: "We prefer to sit around the table with the client at an early stage in order to help think about smart techniques and efficient construction logistics. For example, we realize complete construction pits for contractors so that they have more preparation time for the construction project itself." 

Continue to pioneer

In the spirit of Frankignoul, Franki Grondtechnieken is constantly working on new developments. Processes are becoming increasingly efficient and equipment smarter. For example, new machines are equipped with a GPS system for the most accurate geolocation. And the injection department uses a technique in which bacteria in the soil are activated to secrete lime. That lime binds with the sand, which is a lot more environmentally friendly than injecting chemicals. Verhoeff: "In addition to digitalization and environmental protection, safety and inner-city construction are becoming increasingly important. We continue to pioneer in order to stay ahead in all these themes."
