Frequently Asked Questions

Does invasive pole inspection reduce pole strength?
To some extent, although it is not necessary to drill a hole any larger than 1/2". It has been shown mathematically that 3 - 1/2" holes drilled at 45 degrees 120 degrees apart will reduce a 40" circumference pole by less than 1.5%. Most procedures call for 6" vertical separation of drill holes reducing this to less than 0.5%. 
Are the chemicals used for treatment toxic?
OPIS Inc. prefers to use products that are the most environmentally responsible and safe. We have found that Genics Inc. has the best wood pole treatment products available. The products have toxicity to mammals, somewhere between that of salt and table sugar. 
I have noticed that many utilities only check the pole above ground. Is below ground inspection necessary?
Yes! It is imperative that the shell below ground line be checked for surface decay. 
Most of the strength of a wood pole lies in the outer 2" of the pole.
