Installing Standpipe Piezometer in Borehole
1
Flush borehole with clean water. Attach filter tip to pipe. Add additional lengths of pipe as standpipe
is lowered into borehole, sealing joints with tape or glue. Continue adding pipe until tip has reached
required depth.
2
Place sand around tip using tremie pipe. Sand must be wet to tremie successfully.
3
Place bentonite seal. Drop pellets or chips into borehole slowly to avoid bridging. Use of flush cou-
pled pipe also helps to prevent bridging. Add water as needed for hydration of bentonite. Allow time
for bentonite to swell.
4
Fill remainder of borehole with bentonite or bentonite-cement grout.
5
Cut standpipe to length. Top off borehole with grout and install protective cover. Hand over to client
after proving installation.
