Rammed and Bored Cast

The oldest known ground-engineering elements are rammed or driven piles timber piles. After thousands of year’s technology made many more rammed pile types possible but the highest load bearing piles would be only possible with the different types of Bored cast in situ pile, which became very common.

Very common applications of bored cast in situ piles are not only load bearing piles but also piles for retaining wall structures, such as Secant Pile Walls – where piles in a raw are intersecting each other and contain soft (non-reinforced) and hard piles (with reinforcement), and Contiguous Pile Walls – where piles are aligned and just tangentially touching each other, and as socketing-base of Berlin Walls, whereby all types are mainly supported by
