Biochemical consolidation of soft and deteriorated wood: Biokemisk konsolidering af blødt, udvendigt træ.

If the timber in a half-timbered building has started to rot, e.g. the foot strap as seen here, the most usual practice is to replace it with new, undamaged timber - either completely or partially (partially). But it often requires greater bracing as well as some or all of the brickwork being removed from the nearby slab - and much more. If the rot damage is only 'superficial', i.e. that you can stick a knife or awl approx. 1-1½ cm in, before it stops, this can be repaired with hot wood tar - through a 'biochemical consolidation'.
