Anyone have any experience, good or otherwise, with using this system?
Workmate has a project to design a boardwalk in a wetland area with a seismic D class in clay/sand, as opposed to using pin pile driven to re3fusal at 20 to 25 feet.
I am concerned about liquefaction of the soil mass and the behavior of the system in such an environment. The geotech we are dealing with helped develop the system... I am also concerned with the possibility of vertical settlement. The only attachment appears to be a binding or pinching force of the pins to the concrete head coupled with interstitial friction. I see nothing physically locking the pins to the head, only a seal cap to prevent water intrusion from the top, which is academic in my opinion as it could intrude from underneath and cause a freeze/thaw action.

RE: Diamond Pier System
The pins on the proposed system don't seem to carry the loads below 63 inches or so but they may be creating a large pressure bulb?
I vote for a test. Why is there no reference to the Geotech in the video literature?
