These piles are built to improve the bearing capacity of the ground. The excavation of the piles is carried out by hydraulic or mechanical punching and after that the equipment is placed and the concrete works are carried out respectively. The methods applied during the drill are determined by the condition of the field. Pile diameters are between 45 and 300 cm. The use of containment pipes or bentonite mud may be required considering the structure of the ground and groundwater level, pile length and diameter and equipment. With this method, the structure load is born by a solid ground.
