Franki piling system

[2] This method can be applied to different site conditions and is still widely used[2][3][4] due to its high tensile load capacity, and relatively low noise and ground vibration levels.

[3] Edgard Frankignoul applied for the production patent for the Franki pile in July 1909.

He then co-founded the geotechnical company Frankipile (Société des Pieux Armés Frankignoul) with Liège aristocrat Edmond Baar with the goal of commercializing the Franki piling system.

[2] Before this innovation, the casing had to be top-driven and equipped with a lost bottom plate.

[2] Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering.
