Protective Levels of Borates in timber Foundation Piles 5 – 18 Years after In-situ Remedial Treatment in Areas with Wet Clay Ground Conditions. The Jerbor and Eurobor Protocol, Part 1.
2011 - IRG/WP 11-30571
Timber has been used as foundation piles and grillages for decades or even centuries. Since the late 1970s a method for investigate, analyze and treat building timber foundations in soft clay grounds against decay fungus with a biocide have been developed and used by the late professor Allan Jerbo. Settling…
