Wet rot refers to a form of wood decay that occurs as a result of prolonged exposure to excessive moisture or damp conditions, which provides an ideal environment for fungal growth. It is a common problem in buildings and structures, particularly in areas where there is inadequate ventilation or high levels of humidity.
When wood is constantly exposed to moisture, whether from leaks, condensation, or prolonged dampness, it becomes vulnerable to wet rot. The moisture content in the wood increases, leading to the growth of certain types of fungi, such as Coniophora puteana or Serpula lacrymans. These fungi break down the structure of the wood, causing it to soften, darken, and become brittle.
Wet rot primarily affects the wooden components of a building, such as joists, beams, skirting boards, and window frames. As the fungi continue to grow and spread, they can cause significant damage to the structural integrity of the affected wood. In severe cases, it can result in the collapse of the wood, posing a risk to the safety of the building and its occupants.
To prevent and treat wet rot, it is crucial to identify and address the underlying moisture issue. This may involve fixing leaks, improving ventilation, or implementing proper drainage systems. If wet rot is already present, affected wood should be removed and replaced, and any remaining timber should be treated with specialized fungicidal treatments to stop the spread of the rot.
Overall, wet rot is a destructive fungal decay process that affects wood due to excessive moisture, leading to the deterioration of the wood's structure and potentially compromising the integrity of a building.
