1: A diesel hammer or Fundex hydraulic hammer is used to drive a steel tube into the ground until the foundation level is reached.
2: After checking that the tube contains no water, the reinforcement cage is placed and the tube filled with sufficient concrete to form the pileshaft.
3: The piletube is extracted approximately 2 m by using the Fundex vibrator and refilled with concrete.
4: The tube is closed at the top and driven into the ground again, so that the concrete is compressed and an enlarged base is formed.
5: The vibrator is clamped around the tube to extract it. During extraction the shaft is formed and the pile is ready.
