Hello!

Things moved quickly when the beam was finally in place. The plan was to "seal off" the space that was left after the previous reinforcement. I used some scrap pieces from the dismantled aerated concrete wall and Casco's house fix. However, what I missed was placing some other material between my "masonry" and the end grain of the glulam beam. I am aware that cement and wood do not work well together, but do you think the glulam beam has suffered any damage from potentially short-term moisture absorption from the house fix? It was left open for a couple of weeks before I put up the gypsum. Now everything is plastered and painted and I didn’t realize my mistake until now...

I think that any moisture the wood might have absorbed should have had plenty of time to dry out, plus it’s not like the beam is "encased." There is no risk of additional moisture exposure.

Am I thinking correctly and can I let go of the thought?

It's not that wood and concrete don't get along...

The problem is that if a wall/pillar or other casting is in wet/damp soil, moisture can be transported up to the wood, and then the wood can be damaged.

So if you don't have any moisture transport to your beam, there's no danger.

Haha, Good point! The wall is not wet. Thank you for your answers, I now understand that it is primarily the moisture transport that is the problem, not temporary moisture.
