Casagrande Porous Tube PiezometersThe top Porous Tube Piezometers manufacturers and suppliers are from Roorkee, Uttarakhand. Casagrande type porous tube piezometers are used for measuring and controlling pore water pressure in soil and rock and to monitor the construction control and stability in embankments, dams, and reservoirs. A standpipe, with a porous piezometer tip connected at its lower end, is installed in a borehole. Bentonite and/or grout are used to seal the borehole above the "tip". The water level inside the "standpipe" is measured with the help of an electronic water level indicator and corresponds to the water pressure at the piezometer elevation. When required, the permeability of soil in the vicinity of the tip can be determined by increasing the water head in the standpipe, and observing its dissipation rate. Advantages: - (a) ideal fordermining the piezo-metric level during routine site investigation. (b) can also be installed after the completion of construction & therefore suitable for use in existing dams and embankments. The wide demand for our Porous Tube Piezometers testifies to its quality as well as performance levels.

• Monitoring pore-water pressure to determine the stability of slopes, embankments, and landfill dikes.
• Monitoring water draw down during pumping tests
