I googled today on how to level a basement floor. Most people recommend using SLC (self leveling concrete)... I don't think I can just use that because of the pitch of my floor (and from what I hear, the price of SLC). The house was built in the 1930's and has settled since then. Its higher in the middle. About 3-4 feet away from one of the walls it start to dip and at its lowest its about 4 inches down.
So what I imagine I can do is this:
- Clean the floor
- Use some sort of primer so that the concrete sticks together
- Pour regular concrete, so that it comes close to level
- Once that drys use the primer on top of that
- Pour SLC
Will the SLC be strong enough to support wooden beams for the walls - that will be butt up against the joists near the wall?
What would your recommendations be? Please note that I plan on finishing the basement so I will be putting horizontal wooden beams around the room with drywall in front.
As a bonus question. There are two wooden joists in the ceiling in my basement that are holding up my fridge in my kitchen (as well as a wall). They have warped (sagging) about 1/2 - 1 inch and I would like to put a supporting beam underneath it in the basement. What can I get to very gradually lift the beam back in place so that I can place the supporting beam underneath it?
