Resistograph Electronic Drill Testing

Is  a modern electronic drill that can  provide a graphical representation of the type and extent of decay in a pole.  Wherever necessary both at, and below ground line measurements will be done, especially below ground line.  The Resistograph uses a 1.5 - 2 mm drill bit and it causes very little or no damage; there is no need to plug the hole. No excavation is normally necessary to assess the internal decay below ground line.

Traditional Sound & Bore Testing 

Gas or electric drill and shell guage to detect internal decay below or at groundline.

Possible information Obtained from Testing

• Pole strength and life
• Mechanical, insect & woodpecker damage
• Surface rot and cracks
• Feathering at top
• Crookedness & out-of-plumb
• Decay at and below GL
• Pole height, conductor size & level, span, accessories, etc.
• "snapshot" of pole and severe damage
