Micropile Video Added

A new video has been uploaded to my YouTube Micropile page. Micropile Drilling Process in Karst is a six-minute clip showing the drilling process used for rock socketed micropiles in Karst geology. The video shows casing advancement through overburden, drilling of the rock socket and removal of the drill string and hammer. This drilling was performed using an excavator-mounted drill rig, a down-hole-hammer overburden drilling system and seven inch casing. You can view my videos at http://www.youtube.com/user/JonathanBennettPE. Let me know if there are particular things you want to see.
