Not every type of soil is equally suitable for constructing buildings. If the load-bearing capacity of the upper soil layers is insufficient, these layers can be bridged by using pile foundations. The structural loads are transferred to deeper layers with a higher load-bearing capacity with the aid of piles, also known as pilots. The loads are transferred via the friction of the piles (shaft friction) and via the contact surface of the pile foot (peak pressure).
Our experts determine the cross-section and length of the piles on the basis of the soil conditions and the size of the pile loads that are to be transferred. The materials used to produce the pile foundations also vary depending on the intended use, soil conditions and the surrounding conditions. Nägele Hoch- und Tiefbau primarily uses precast reinforced concrete driven piles and timber driven piles.
