Dry Rot Treatment refers to the techniques used to eliminate dry rot fungus and alleviate the damage done by the fungus to human-built wooden structures. The commonly held view of an outbreak of the dry rot fungus (''Serpula lacrymans'') within a building is that it is an extremely serious infestation that is hard to eradicate and requires drastic remedies. The traditional “orthodox” approach to treatment practised by most remedial timber treatment and damp proofing companies accordingly specifies the stripping out can be eradicated simply by controlling the environment of the area in which it is growing in terms of reduced moisture levels and increased ventilation. It is universally accepted that the first priority is to make repairs to rectify the cause of the dampness within the building that allowed the dry rot outbreak to occur in the first place and to promote the drying out of the affected area by taking measures such as increasing ventilation. It is in the way in which the affected building fabric is treated after this that the approaches differ. ==Mycology of ''S. lacrymans''== ''S. lacrymans'' is a form of brown rot, a group of fungi which digest the cellulose and hemicellulose in timber. This particular species poses the greatest threat to buildings since it can spread through non-nutrient providing materials (e.g., masonry and plaster) for several metres until it finds more timber to attack.〔Palfreyman, J. W. & Low, G. (2002) Studies of the Domestic Dry Rot Fungus Serpula Lacrymans With Relevance to the Management of Decay in Buildings, Edinburgh, Historic Scotland〕 Dry rot is spread by spores which are present in most buildings. The minimum moisture content of timber for spore germination is 28–30% (lower than other rots), and the relative humidity must be in excess of 95%. Spores are resistant to desiccation and may still be viable for germination when they are several years old.〔Ridout B. (2000) Timber Decay in Buildings, The conservation approach to treatment, London, Spon〕 If conditions are suitable, the spore will germinate producing microscopic fungal threads called hyphae. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dry rot treatment」の詳細全文を読む スポンサード リンク
