Depending on the application length, diameter, material, formation, and placing of the individual piles can be adapted.
 
Kelly Method
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.
