Borehole Condition Assessment


Cost-effective evaluation using a combination of down-hole video cameras and various other geophysical techniques.

The condition of a borehole is paramount to its on-going performance. Checks on newly drilled boreholes ensure that design and specification have been met and allow benchmark readings for monitoring future hydro-geological changes.

Checks to existing boreholes should be made part of an on-going maintenance programme, thus highlighting any potential problems before they develop into major problems or disruptions in supply. Prior to the decision to rehabilitate a borehole, various methods can provide vital information so that the most suitable and economical decisions can be made.

Existing Boreholes


  • Locates and identify causes of obstructions.
  • Determines the condition of casings.
  • Identification of corrosion and bio-fouling.
  • Evaluation of cement grouts.
  • Location of voiding behind linings.
  • Measurement water quality.
  • Locates running sand.

New Boreholes


  • Verifies correct type, size and positions of casings and screens.
  • Checks the integrity of casings, grout seals & borehole stability.
  • Provides benchmark data for monitoring changes.
