'''Wet rot''' is a form of [[wood decay]] caused by [[fungi]] that thrive in damp conditions. It is a significant issue in the preservation of [[timber]] structures, particularly in buildings where moisture control is inadequate.


Wet rot is a type of fungal decay that affects timber and other organic materials when they are exposed to excessive moisture. It is a common problem in buildings, particularly in areas with high humidity or water leaks. Wet rot can cause significant damage to the structural integrity of a building if left untreated.
== Causes ==
 
Wet rot occurs when wood is exposed to excessive moisture, typically above 20% moisture content. This environment allows certain fungi, such as ''[[Coniophora puteana]]'', to colonize and break down the [[cellulose]] and [[hemicellulose]] in the wood, leading to structural weakening.
=== Causes ===
 
Wet rot occurs when timber is exposed to moisture levels above 20%. The main causes of wet rot include:
 
1. Leaking pipes or roofs: Water leaks from pipes or roofs can lead to damp conditions, providing an ideal environment for wet rot to develop.
 
2. Poor ventilation: Insufficient airflow in enclosed spaces can result in moisture buildup, promoting the growth of wet rot fungi.
 
3. Condensation: When warm air comes into contact with cold surfaces, condensation can occur. This can create a damp environment that encourages wet rot.
 
=== Signs and Symptoms ===
 
Identifying wet rot early is crucial to prevent further damage. Some common signs and symptoms of wet rot include:
 
1. Discoloration: Affected timber may appear darker or have a brownish or reddish hue.
 
2. Softness: Infected timber becomes soft and spongy to the touch, as the fungi break down the wood fibers.
 
3. Crumbling: The affected timber may crumble easily when pressure is applied.
 
4. Musty odor: A damp, musty smell is often present in areas affected by wet rot.
 
=== Treatment and Prevention ===
 
Treating wet rot involves removing the source of moisture and replacing the affected timber. The following steps can help prevent wet rot:
 
1. Maintain good ventilation: Ensure proper airflow in enclosed spaces to prevent moisture buildup.
 
2. Fix leaks promptly: Repair any leaks in pipes, roofs, or gutters to prevent water from entering the building.
 
3. Use damp-proof membranes: Install damp-proof membranes in areas prone to moisture, such as basements or crawl spaces.
 
4. Regular inspections: Regularly inspect the building for signs of dampness or decay, and address any issues promptly.

A type of fungal decay affecting timber


Wet Rot[edit]

Coniophora puteana, a common cause of wet rot

Wet rot is a form of wood decay caused by fungi that thrive in damp conditions. It is a significant issue in the preservation of timber structures, particularly in buildings where moisture control is inadequate.

Causes[edit]

Wet rot occurs when wood is exposed to excessive moisture, typically above 20% moisture content. This environment allows certain fungi, such as Coniophora puteana, to colonize and break down the cellulose and hemicellulose in the wood, leading to structural weakening.

Identification[edit]

Wet rot can be identified by the following characteristics:

  • A damp, musty smell
  • Discoloration and darkening of the wood
  • A spongy or soft texture
  • Cracking or crumbling of the wood surface

Common Fungi[edit]

Several species of fungi are known to cause wet rot, including:

Prevention[edit]

Preventing wet rot involves controlling moisture levels in buildings. This can be achieved by:

Treatment[edit]

Treatment of wet rot involves:

  • Removing the source of moisture
  • Replacing or repairing affected wood
  • Applying fungicidal treatments to prevent recurrence
