Drilling a test hole for a future UBC law library geothermal extension project, a sonic rig was able to bore past 300 ft. and complete the hole in two hours and three minutes. No other drill exists that could do the job any faster.
Over the years, sonic drilling has been used for many fascinating projects but none more so than drilling inside a building and through hidden railway track.
Any condo complex under construction can certainly test the patience of those who live and work nearby but nothing is more taxing that the repetitive pounding of a pile driver.
Kept secret for a year until patents could be filed, sonic pile-anchors, which allow a building to rest on top as well as be bolted and anchored to them, were finally unveiled.
