Installing Push-In Piezometer in Borehole
Pneumatic, VWP, or VS Piezometers
1
Saturate filter and piezometer. Flush borehole with clean water. Check that piezometer functions
correctly and obtain “zero” readings of VS and VWP piezometers. Attach push-rod to piezometer.
Lower piezometer to bottom of hole, adding rods as necessary.
2
Hand-push piezometer into ground at bottom of borehole. Read piezometer continuously to check that
pressure generated by pushing does not exceed instrument maximum. Retrieve rods.
3
Check that piezometer functions, then place bentonite seal. Drop pellets or chips into borehole slowly
to avoid bridging. Add water as needed for hydration of bentonite. Allow time for bentonite to swell.
4
Fill remainder of hole with bentonite or bentonite-cement grout.
5
Terminate tubing or cable to prevent entry of water. Top off borehole with grout and install protective
cover. Prove installation and take initial reading, then hand over to client.
