Casagrande Porous Tube Piezometer

Casagrande porous tube piezometers are used to monitor piezometric water levels. Observation wells are used to monitor ground water levels. Water level readings are typically obtained with a water level indicator. Typical applications include:

• Monitoring pore-water pressure to determine the stability of slopes, embankments, and landfill dykes.
• Monitoring of ground improvement techniques such as vertical drains, sand drains, and dynamic compaction.
• Monitoring dewatering schemes for excavations and underground openings.
• Monitoring seepage and ground water movement in embankments, landfill dykes, and dams.
• Monitoring water drawdown during pumping tests.
