PND Engineers' Soils-Material Lab is furnished with state-of-the-practice secondary testing equipment from Geocomp Corporation. The lab can perform the following secondary tests:
- Consolidation with rebound and reload points
- Triaxial tests
- Thaw settlement
- Thaw consolidation
- Frozen soil creep testing
PND personnel are factory trained as Pile Driving Analyzer (PDA) technicians with the Case Pile Wave Analysis Program. The PDA technology is the most widely employed system for dynamic load testing and pile driving monitoring in the world. The high-strain dynamic load tests assess the capacity, integrity, and driving stresses during the installation of driven piles.
PND's trained geotechnical engineering and testing staff is also capable of performing the following:
- Cone penetrometer tests
- Dynamic cone penetrometer tests
- Downhole vane shear tests
- Ground-penetrating radar and electrical resistivity tomography surveys
- Subsurface ground temperature profiling
