IML Pole Inspection


How stable is the pole?

As only faultless poles comply with the high security requirements
timber poles must be examined regularly for stability.

The problem:
Often, possible defects are located in the interior of the poles and can’t be identified from the outside. About 90% of all the timber pole defects or damages are located below the soil level and it’s necessary to carry out complex investigations or excavations or excavations to detect them.

IML Resistograph System

The different series of the IML Resistograph System are available with different drilling depths. The F-Series prevails in the field of utility pole inspection. With the IML Resistograph System you can drill an every height of the pole, from the soil level to the top end of the pole. It takes you less than a minute-including the measurement profile printout.

In Germany and all over the world the IML Resistograph System has been used for years to inspect utility poles.

Thus you can examine the IIML Resistograph F-Series optionally with an  Bluetooth electronic unit that detects the drilling profile directly on the instrument saving simultaneously date, time and an arbitrary project name of the drilling. That way, afterwards it is easy to assign the measurement data.

The attachable 45 adapter enables you to examine the critical area where the wooden pole enters the soil without problems.
The excavation around the pole becomes redundant and you can save precious time. You can make the measurements directly on the soil level and evaluate them instantly.

The IML Resistograph System helps you:

  • Detect and secure damaged wooden parts even in early stages of deterioration
  • Detect root in various stages
  • Detect cracks and cavities
  • Take the required measures early enough to prevent damages (thanks to the detailed evaluations)
  • Document quality differences between wooden beams

Economic advantages:

  • Profitability because of little work with high efficiency
  • Time saving because on fast measurements
  • Optimized employment of stuff
  • Cost saving less exchange work and little raw material
  • Prevention of unnecessary wood damages: the sawdust remains in the bore hole and closes it after measurement
