 popit UTA Study on POPIT Lift Hole Plugs
UTA Study on POPIT Life Hole PlugsThe key point when installing the POPIT plug is to make certain that the “ribs” grab onto the inside of the hole, which will secure the plug in place. Since the POPIT plug is neither watertight nor airtight, the goal of this study is to subject the installed POPIT plug to internal pressure while subjected to 30 ft of backfill.

 hdpe UTA Study on HDPE
UTA Study on HDPE: This study is a part of a major initiation on health monitoring of underground structures in which a new state-of-the-art laser profiler is being developed. Thus, data is being collected from flexible pipe systems for comparative purposes. This report presents the initial results of video and laser inspections of HDPE pipelines in 61 site locations in 10 states throughout the nation.
