Looks like good timber above, but it is rotten on the inside

This is a classic example of why the Mdu Probe System is so helpful in determining damage. An Mdu Probe was installed into the bottom plate of a wall, and damage was found inside it as well as an elevated moisture content. The gib was then removed and the surface of the timber shows no evidence of the decay inside the timber. Had the Mdu Probe not been installed in this area, then a ‘visual inspection’ by removing gib and examining the timber surface would have given the impression that the area was perfectly ok when in fact it was hiding damage and high moisture.

This phenomenon is often repeated in many instances and gives insight as why many structural issues are missed by structural and moisture inspections carried out internally, through the gib or non-invasively.
