Bored Piles are circular piles made of concrete and steel being installed in the soil by various drilling methods. They divert high structural loads into deeper, stronger soils, form stringed together a retaining wall for excavation pits or terraces remove obstacles in the soil or block ground water below the surface.
Depending on the application length, diameter, material, formation, and placing of the individual piles can be adapted.
With the Kelly method, uncased, partially cased, fully cased or slurry piles are produced. The drilling tool is fixed to a telescopic Kelly bar. It is drilled step by step into the soil. If fully cased piles are produced, the casings are drilled to the necessary depth and bored until the final depth is reached.
