Inclinometer Casing

  • Do you have any instructions for installing horizontal casing? I'm planning to embed the casing in a foundation slab.
  • How does inclinometer casing behave in soft soil? Does it deform sufficiently to detect the shear zone or does its stiffness simply distribute the movement?
  • In the winter, water in my inclinometer casing tends to freeze, and I can't obtain a survey. What can I do about this?
  • Should I used large, medium, or small diameter casing?
  • Is a bentonite grout, such as Volclay, suitable for backfilling around inclinometer casing?
  • Why does casing tend to float in grout?
  • My casing was not oriented correctly during installation. The A-grooves are misaligned about 10 degrees from the actual direction of movement. Is this a problem?
  • We want to install an inclinometer to monitor deformation within our cast-in-place, reinforced concrete retaining wall. We intend to tie a heavy-gauge PVC pipe to the reinforcing cage. Then when the wall is cast, we will drill about 6 meters below the bot
  • We want to install an inclinometer with our sheet-pile walls. Do you have recommendations for how to do this?
  • For best results with my inclinometers, must my boreholes be very close to vertical?
  • I want to add torque strength to the QC coupling. Is there a way to do that?
  • Do you have any advice for installing casing in deep boreholes?
  • What is the expected yield for the recommended grout mix designs?
