Drive-in piezometers, also called push-in piezometers, are designed for installation in soft clays, organic or fine grained cohesionless soils.
The piezometers are pushed directly into the soil using conventional cone penetrometer or drilling rods with adapters.
The large diameter nose cone decreases the chance of overpressure while the piezometer is pushed into the soil.
• Pore pressure in soft soils
• Dams and fill embankments
• Dewatering activities
• Natural or cut slope sites
• Deep excavations
• Diaphragm walls
• Cable length does not affect reading
• Long working life and reliability
• Built-in surge protection (vibrating wire only)
• Built-in temperature sensor
• Dynamic pore pressure monitoring (piezo-resistive only)
