A new video has been uploaded to my YouTube Micropile page: Limited Access Hollow Bar Micropile Installation. Hollow bars can be the ideal foundation solution in this application because they do not require as much hardware and equipment as conventional cased micropiles. Hollow bar segments can easily be carried by hand whereas casing and downhole hammer equipment often will require a forklift or other mechanical assistance to move. WARNING: The US Surgeon General has determined that smoking is hazardous to your health. You can view my videos at http://www.youtube.com/user/JonathanBennettPE. Let me know if there are particular things you want to see.
