For the last 12 months, we have had the opportunity to work on an industrial building that was severely distressed. We reasoned that this would provide extra assurance. If we installed micropiles we would need to make assumptions about the soil below the landfill as we had no information about it from borings. With a push pile we could simply drive to refusal….. 60,000 pounds. Some of the piles at first indicated that we were going through rough cobbles. They jerked around and made popping noises as they push through the cobbles. Others however did not. And some went way deeper than we anticipated up to several hundred feet. No one still to this day understands completely what is going on at those depths. We eventually did reach refusal.
