Envco – Environmental Equipment

The Model 615 Drive-Point Piezometer is designed as an affordable method to monitor shallow groundwater and soil vapor in suitable conditions.

Ideal for:
• Water level monitoring
• Construction control
• Slope stability investigations
• Soil gas monitoring
• Permeability measurement
• De-watering/drainage operations
• Metals monitoring

The Drive-Points attach to inexpensive 3/4" (20 mm) NPT steel drive pipe which is widely available through local plumbing and hardware stores.

Solinst Drive-Point Piezometers are most often installed as permanent well points. They can also be used for short term monitoring applications.

High quality samples can be obtained if polyethylene or Teflon® lined tubing is attached to the stainless steel drive point. Groundwater sampling and hydraulic head measurements can be taken within the tubing using small diameter equipment, as described here.

Solinst Drive-Point Piezometers can be driven into the ground with any direct push or drilling technology, including the Manual Slide Hammer shown below. To avoid clogging or smearing of the screen during installation, a shielded version is also available.
Drive-point piezometers are not suitable for all sites. The depth limitations vary, especially with soil conditions and the drive method used. Model 615 Drive-Point and Shielded Drive-Point Piezometer
