Fugenex Dry Rot Sensors are a simple to install treated wooden dowel that changes colour, from blue to yellow, in the presence of incipient Dry Rot.

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.

Dry Rot Detectors are installed by drilling an 7mm-10mm diameter hole to a depth of 100mm in the ‘at risk’ timber or masonry (if it is felt the material you are drilling into may shrink then it would be prudent to drill 8-9mm diameter hole). 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.


Benefits:
  East dry rot detection
 No need for destructive survey, cornices and ornamential woodwork can be saved.
  Early recognition of dry rot fungus.
  Growth can be monitored.
  The full extent of spread of dry rot can be mapped out.
  Environmental control methods can be implemented and evaluated.

What is Dry Rot?
Dry Rot, the decay of timber by the fungus Serpula Lacrymans, is the most serious timber decay problem in buildings. The fungus decays timber components and without remedial action considerable structural damage can ensue.

The unique ability of the dry rot fungus to penetrate the non-timber elements of buildings, such as masonry and plaster, in the form of mycelial strands, and to transport water through those strands, allows the fungus to spread considerable distances from its point of origin.

Finding dry rot and determining how far it has spread was therefore difficult - until the arrival of Dry Rot Sensors.
