Control of dry rot without biocides

Borehole impregnation is generally used for the treatment of masonry to combat dry rot (Serpula lacrymans). This often leads to irreparable damages to quarrystone masonry. Over the last 30 years, the author has sought alternative dry rot control methods. The hot-air process for combating dry rot is well-known and has meanwhile been included in the publications of the German Institute for Standardization (DIN). The process with microwave devices is based on the similar principle whereby there are economical solutions for small areas. Completely new is the process using lithium water glass which also requires no borehole impregnation and does not contain any biocide. Here the masonry is only treated by spraying.
Sufficient experience is available on both procedures and the systems have been tested and approved by various laboratories.
