Floor fiasco!!

[lupinfarm]

This is really an update on my previous post on my kitchen floor re-do.
Here are some pictures which show how the floor is structured. I think the footings are only about 8 inches deep. Any comments and suggestions on how to structure this properly would be appreciated.
The joists are supported on that beam that runs from the foreground to the back ground of the image and the beam is supported on rock piles. The joists are laid flat ( wide side down) on the sill. Oh and I forgot to mention the cement sill isnt
the same height all the way around.

Lupinfarm, I have only one question. Is any of that floor structure rotting? If not all I would do is maybe add a few support footings under the main beams or were there is a long Span between supports. For a house as old as yours, the fellow who built it did a good job. Not even Mr. Holme could can condemn a structure that survived 140+ years. The floor is opened up and would make a great opportunity the male it last another 140 .

Yes the beam has dry rot at one end and one of the joists has dry rot.
DH is home next weekend and he has a few ideas. My problem is that
The floor is ery bouncy and slopes.

Wow! I am by no means a construction expert but never have I seen floor joists laid on their side. That's gotta be one of the contributing factors to the bouncyness. Very interesting.

I think if you want to take a shortcut you could through bolt sisters to each beam as necessary and "add a few support footings under the main beams or were there is a long Span between supports". I would also try to cover the dirt with plastic and insulate the floor and whatever possible.

Nezwick.... Yep my house breaks "ALL" the conventions of good construction.
I think I have to "face facts" the old structure is no longer working
and will have to come out. Just trying to figure out a permenant
solution. I would feel terrible passing this onto a future home owner.
Unfortunately I don't have the budget to hire a professional to do the
work.
MrHenry.... I don't think sistering joists is going to work . The
Existing structure is rotten and bowed right down. I should have married
A Contractor not a Geek. My plan right now is
1. Remove and level the ground beneath the joists.
2,Lay plastic or spray foam sill
3. Remove and restructure and re sheet floor deck with 5/8 plywood
The only question is how to attach a ledger rail to the existing
Cement sill, as the sills around the room are different heights . Also
, oh I feel another question coming on. And what hardware do I use to
Attach the ledger rail to the sill.
Is there anyone on OHW who has had a problem like this?

Could you rent a cement saw and cut the sill down to being level?

I see two completely different appraoches.

Either you build a new floor, which is essentially sitting on its own piers, aonly nailed/bolted to the walls to keep it from moving sideways. Or do it the European way. Pour concrete to get a level and solid surface, waterproof the concrete and lay a floor on 2x4 sleepers supported with wooden blocks every few feet. Before you put down the finished floor, insulate between the sleepers.

Hi Texasranger .. Actually one of the numerous Contractors
That looked at it suggested putting in a cement pad and sleeper
Joists. It would cost me about $2,000. Cdn to have it done and
About $500 for the permit from the Township to allow the
Pumpcrete truck to have access to make the delivery. Then there is
The building permit it self. So I guess it's on to plan "b"
Which would be way cheaper. Although I would prefer plan"A".
I'm a Mercedes girl on a Chevy budget I'm afraid.

Do you have time and patience? Then get an electric drum mixer. I'm fairly sure our mason used one for the concrete pads in our entire house. You still might want to get someone involved who is experienced in leveling concrete, but it shouldn't be that expensive I guess.
