What is it?
A simple to install treated wooden dowel that changes colour, from blue to yellow, in the presence of incipient Dry Rot.
What does it do for me?
It allows you to tell if Dry Rot is present at its earliest stages, in timber or masonry, giving you an early warning that action is required before your building is damaged.
How is it installed?
By drilling an 7mm diameter hole to a depth of 100mm in the 'at risk' timber or masonry.
How does it work?
The blue detector dye, that is vacuum impregnated into the wooden dowel, reacts to the chemical that Dry Rot produces - oxalic acid - at very low levels, turning the dye to yellow.
