What happens here

This video demonstrates a professional installation process of helical piles, which are used to support or stabilize building foundations. The process involves using heavy machinery, specifically an excavator with a hydraulic auger drive head, to screw multi-section helical piles deep into the ground. The video shows the initial driving of a pile, the attachment of an extension section, and the continuation of the driving process. It is crucial to note that this is a highly specialized task requiring professional expertise, heavy equipment, and adherence to engineering specifications and local building codes, and is NOT a typical DIY project.
