Learn how to achieve consistent quality of in-place backfills in this workshop, which discusses the mixing and placement of backfill materials for closed loop ground source heat pump applications. Vertical and horizontal loop applications where backfill materials are placed by the pressure tremie method will be reviewed. Mixing and placing thermally enhanced materials is quite different from conventional grouting materials regarding equipment and execution. Proper mixing is crucial to predictable placement and performance of thermally enhanced materials. Sample recovery techniques for you to implement to satisfy design-engineering requirements for follow-up and quality control testing will be covered, as well as the minimum equipment requirements needed.
