Saggy floor repair

Bought a house. Had some saggy floor sections. One is "okay" and will probably be fine for a year or two more. The other was in a laundry/utility room and was really saggy. The house has been added onto. I believe it had been a back patio prior to the addition. The section was roughly 4x8' and surrounded on 3 sides by concrete. No clue why this section wasn't concrete. Maybe an old stoop and doorway was there prior? I don't know.

Options after removing rotted wood: fill it in with concrete? Dig it out and rebuild the floor? Since it was basically sitting on the dirt I decided to dig it deeper and rebuild. Easier fix. No chance of redirecting the flow of water (if there is any water getting under there). And if done properly I shouldn't have to worry about it again.

Since it was surrounded on 3 sides by concrete it helped give me something to work with. We dug it down deeper. Drilled the boards and concrete. We used tapcon screws to secure the boards to the concrete. We secured them 5/8" below the lip of the concrete to allow for the treated 5/8" plywood to sit flush with the concrete. Once the boards were secure we used joist hangers and made new floor joists. All the lumber was treated. We also placed thick plastic on the ground below as well as stapled some to the bottom of the new floor joists.

I have done this before when entire sections were rotted. This project was much easier. No interior walls to move, tear down, rebuild, or work around. I must admit this is a project I would have called and discussed with my father in the past. Feels good knowing I had the right plan. Still would have been nice to be able to call Dad to confirm my plan of attack was solid. Sure do miss him. Since he isn't around to pick his brain I called our very own Beener. He heard me out and agreed with the plan. Thank you Charles! It was nice talking to you. It was nice getting your professional in put as well!

The before picture doesn't do the rot any justice. Not a good angle. Most of it was sitting on the dirt and I used my hands to pull it apart. The linoleum was the only thing holding it together.

All the new looking tools is the scary part.[emoji23] looks good man. Does kinda make a man wonder why it wasn’t the same though. Probably glad you didn’t dig much deeper and start finding bodies.

Good stuff man. I hate. Hate. Hate. Drilling fuggin concrete. I don't have the patience and end up putting the hoodoo on it and burning the bit.

Retired nun lived here the last 20-30yrs. Doubt there are bodies in there unless prior to her moving in.

I did have to buy a new hammer and pry bar. Jig saw also new since the last one burnt up. Orange handled shovel was pulled out of my personal collection. Last two walked off. Darn nice shovels/pry bar/mini excavator tools.
