Large-diameter bored piles and Large-hole drillings - Applications

In-situ concrete piles with diameters of 0.3 m up to 3.0 m are referred to as large-diameter bored piles. For their construction hollow spaces are made in the soil by means of drilling equipment. Depending on soil conditions the excavation is carried out under the protection of a casing or without casing. Subsequently the drilling holes are filled with concrete; according to static requirements a rebar cage is placed before concreting.
