Piezometer used in a geotechnical setting

What are Piezometers?

Piezometers are instruments that measure the pore water pressure within soil, earthfills, foundations, and concrete structures. By providing insights into the water pressure within these materials, piezometers help geotechnical engineers predict and mitigate potential failures. The data from piezometers is particularly important in areas prone to soil liquefaction or instability.

The global market for piezometers features several key players known for their innovative solutions and quality products. Here are the top three manufacturers:

  • Soil Instruments Limited
  • Geokon
  • Durham Geo Slope Indicator (DGSI)

Other piezometer manufacturers are Fondriest Environmental, GeoSense, Sisgeo S.r.l., AMS, Inc., and Ingenjörsfirman Geotech AB.

How Piezometers are used in Construction:

Piezometers are essential tools in geotechnical applications. They monitor soil conditions, pore water pressure, and water pressure in diverse settings such as construction sites, dams, levees, and mining projects. Piezometers prevent many types of faults, including slope instability, foundation failures, seepage issues, and structural failures. Their installation varies based on project requirements, including the fully grouted technique for fast installation and isolation, the sand-packed method for permeable formations, and the push-in method for quick use in near-surface cohesive soils like clay. These instruments provide critical data for safety, stability, and effective risk management.

Manual and Electronic Piezometers: What’s the Difference?

There are several types of piezometers, each suited for specific geotechnical monitoring needs. The primary differences between manual and electronic piezometers are their measurement methods, data accuracy, and ease of data collection.

Manual Piezometers

Manual piezometers require physical readings taken on-site, often using simple tools. They are generally less expensive but provide less frequent and potentially less accurate data. Additionally, manual piezometers don’t allow real-time or continuous monitoring.

Types of manual piezometers include:

Electronic Piezometers

Electronic piezometers use advanced sensors and data logging systems to provide continuous, real-time data. They offer higher accuracy and can be monitored remotely with cloud-based sensor management platforms like the Inzwa Cloud, reducing the need for frequent site visits. 

Types of electronic piezometers include:

Integrate with Any Sensor

Construction Site Case Studies

Construction Vibration Monitoring While Pile Driving on Lake Michigan

“I could see clear rises in vibration levels with each pile being driven. PPV levels remained well below the parameters of the project, which gave us all peace of mind that the home’s structural integrity was not compromised. And the data is captured for future use, should it be needed.“

Construction Vibration Monitoring to Protect Property & Community Relations

“I just put it down outside the house, turned it on, put a sandbag on it and let it run. It was pretty perfect.”
