Hi Folks,


 I have a project that has Douglas Fir glulam beams supporting a wood elevated

walk way used to access condo units on upper levels.  The walk way is exposed to

the weather and has developed insect infestation and dry rot over a long period

of time.  The damage I observed so far is in small areas and not in high shear

nor bending stress zones.  Is there an acceptable wood/epoxy type filler that

will still bond if the decayed wood is routed out and the clean wood is treated

with a wood fungicide?  Also the wood beams are over sized for appearance for

the tributary  DL and LL.


Thanks for any help from the wood gurus out there.
