detection
In order to assess a tree or a wooden pole’s condition and help quantify any internal decay, an IML Resi-F400 drilling resistance device can be used to record the integrity of the timber without the need for destructive testing.
As a very thin 40 centimetre long specially designed drill bit progresses into the wood, the resistance encountered at the tip of the bit is recorded on a waxed paper strip for quick interpretation in the field with an electronic version downloadable for more detailed desk-based analysis. Sound, unaffected wood records high resistance to the forward motion of the drill bit while decay or cavities lessen the resistance depending on the degree of dysfunction encountered.
A series of tests allows the user to map the internal condition of wood within the area tested.
