CanadianBullFrog hydraulic hammer will never get you dirty as that guy in Video. He must got that diesel from other job which using the open diesel hammer.
@MillyVanillification well, you often hit things in the ground, and once you get the pile down so far, you may not be able to pull it back out. plus, this video, they aren't really using string lines to line the pile up right, which tells me they don't much care abouth they're trade.
he welded them. The ends of each pile is made of metal to stop the cencrete cracking whrn it is being put into the ground so if two piles are needed they can be welded
It is an engineering method to improve soil or ground capacity to hold structures above and underground. There are several methods of pile driving; depending on soil geotechnical study undertaken such as the one in the video precast (maybe also pre-stressed) concrete piles, bored piles, auger pile or deep cement mix piling. Hope I have contributed even a little knowledge.
