I have to deal with a timber (4X8) beam that has sufferred from dry rot. I
plan to remove as much as possible of the dry rot and protect the beam from
future moisture. The beam is not heavily loaded and I believe that the
remaining portion of the beam is adequate to carry the load, possibly with
the help of reinforcement or partial splicing with new timber.
My question is: if all of the existing dry not is not successfully removed
(accessibility is not ideal) will the dry rot continue to propagate on the
modified, moisture-protected beam?
