Drilling and installing Piezometer and Inclinometer on Reclaimed Site
Drilling and installing Piezometer and Inclinometer on Reclaimed Site
(OP)
Does anyone have experience in drilling for the installation of an inclinometer and piezometer in a reclaimed site?
I am curious about how do you put in the porous sand and bentonite separately, especially when the soil is collapsing.

Thank you!!

Piezometer installations in loose deposits I typically use mud rotary to prevent heave into the casing. Following drilling the hole is flushed with clean water and then the piezometer is installed to the depth within the casing. Sand and bentonite are back filled concurrent with casing removal to prevent collapse.

Current practice for installing vibrating wire piezometers is to just grout them in place. So drill with mud, lower the piezometers to depth, and grout.
Could do the inclinometer the same way, but is more difficult because it wants to float out on you.
