At Wood Science Consulting (WSC) nondestructive testing is conducted utilizing a Resistograph, also known as a resistance drill. The Resistograph is used to test all types of structural wood elements such as wood piles, utility poles, timbers, dimension lumber, glulaminated timbers, and fire damaged or burned elements. The drill is very effective for the documentation of "sound wood" and hidden damage as a result of wood decay, insects (i.e. termites, carpenter ants, and powder post beetles), and marine borers (Limnoria and Teredo) as well as determining char depths and effective cross sections in burned timbers. The drill is also used for the inspection and condition assessment of trees. In many situations as many as 50 to 100 drillings, or more, are capable of being conducted on a daily basis providing excellent data for structural assessments.
