The essence of the piling process
The drill has been done by unscrewing the hollow drill bit to the desired depth. Then, during the retraction of the drill bit, the soil in the spiral is lifted and the pile is concreted through the hollow drill bit in parallel, for ensuring the stability of the hole. The prefabricated reinforcing steel can be pressed or vibrated into the finished fresh pile. It can be enforceable for a foundation for light and medium-duty industrial, office and residential buildings as well as road and rail bridges.
