I had a soft spot in my living room floor (house is 3-years old) I pulled the carpet back and found a cement type patch that was cracking. I chipped it away and found a three inch round (almost like it was drilled) hole in the 3/4 inch T&G OSB.
Not knowing the best way to fix it, I used silicon to glue a 6 inch square piece of primered 1/8 inch steel to the sub floor and put the pad and carpet back over the floor. The spot is right in the middle of the living room and if I try, I can feel it without shoes on.
In a couple of weeks carpet layers will be in to install Berber and the best pad we could get. I'm not sure if I should leave the "patch" or do something else. I thought about sanding the area down 1/8 inch and then glueing the steel in so it would be flush.
Can anyone offer some advice on this?
Thank you very much,
Ray

Can you get to the underside of this floor? Take a piece of plywood, 5/8 or 3/4, larger than the hole and glue it to the underside of the floor. Cut a piece of plywood that is the same thickness as the floor to fit inside the hole and glue it to the piece you added from the bottom.

That was my first thought...
The crawl space is about three feet high but, running right down the center is a poured concrete wall that has wood support for the I-Joist. The 2x4's are spaced very closely and have diagnal bracing. I am skinny but just can't make it through. I was told that I could go the the very end and cut some of the bracing out so I could fit. This, I was told, is what the builders usually do so plumbing, insulation, etc could be connected. Apparently, the plumbing and insulation was done as they put the sub floor in (or a VERY skinny person was used).
I know this is the proper way to do it. I thought about cutting the hole bigger so I could patch it the way you described only from above but I'm not sure it's really necessary. It's a small hole and the wood is fine right up to the edge.
Thanks,
Ray
