New log home self build, put in a fiberglass tub and surround. Found out after the fact I should have set the tub into wet cement to firm it up so I could keep caulk in place to seal at the surround. Thinking about drilling up thru the sub floor in several places and injecting door & window Great Seal to firm it up.
Has anyone tried this or have a different or better idea? Thanks

I"ve never tried this. Sounds like a tough spot. Great seal expands alot. Maybe fill tub up with water 1st. Good luck.

Thanks I was thinking of filling the tub at least 1/2 full before proceeding and also using the window & door stuff as it does not expand as much and it will be impossible to tell how much I am getting in. Just trying to pick the great minds as to other possibilities.
