TECHNOLOGY AT WORK
Pole testing with the Resistograph System is
revolutionizing the utility pole inspection industry.
The Resistograph System uses a microbit to
measure the resistance of the wood. It is used for
detecting and measuring cracks, voids, cavities,
and decay inside a utility pole.
The instrument is positioned at the pole´s base
to measure wood decay at ground level and can
measure the wood density below ground level
without compromising the integrity of the pole. With
the Resistograph System poles set in concrete
and asphalt can be tested below ground without
The Resistograph System provides an analysis of
the current condition of the utility pole and allows
one to evaluate the results of the inspection quickly
With better information regarding the condition
of poles, more educated decisions can be made
regarding treatment and replacement options.
With this technology, there is an opportunity for
maintenance cost to be reduced by not replacing
poles that still have useful life.

Impel® Rods are a safe, EPA approved decay
protection and prevention system for wood poles.
They are placed into holes drilled into wood poles
at critical locations where control of decay is
Genics Cobra™ Wraps are EPA approved and help
to prevent and stop decay in wood poles at the
groundline. Cobra Wrap exceeds all competitive
treatment products in its eco-sensitive treatment of

Each drilling is converted into graph form giving
you an internal view of the pole.
Due to the detail of information gathered using
Resistograph inspection, poles which may
be identified for replacement using traditional
inspection methods may have extended useful life
