My townhouse was built with Top Chord Bearing Open Web Floor Trusses. They are 15' long X 11.5 deep. They are spaced out 22" from one another. I want to take out a 2' wall to open my kitchen. The wall is under one of the trusses running parallel with it. The truss does not have any vertical...

I will take that as a yes. :(

I bought my house with 5/8" bamboo wood floors recently installed. They have started squeaking more and more lately. After pulling a few up to investigate, it seems like they were glued down to some pretty old plywood. The plywood sub floor seems to be moving around a lot causing the floors...

I am thinking about basement jacks.

There is actually a walk-in in the basement. I also have a drop ceiling in the basement that only has about 5 inches of space in-between it and the joists. I can run support poles on the side of my walk-in every 3 feet with a 4x4 running across the top. Do you think the 4x4 would be heavy enough?

I have a floor deflection problem that has caused a new quarry tile floor to come loose. :mad: It is in a wet environment so water is able to get under the tiles. I am repairing the deflection issues but how should I refinish the quarry tile and grout so that it does not let water through...

I have a restaurant with a deflection problem on the first floor. The kitchen is 15 wide and is supported with 2x12 joists that are pocketed into cinder block walls. Over the past 3 months that the restaurant has been open the grout and tile is coming loose on the floor due to the deflection...

Thanks for all of the help. I wanted to put a gym on my 3rd floor. I will do some more research, but I'm leaning on not doing it from 1 2X4 going into the supporting wall every 2 feet. I have read about load bearing for bedroom floors being as low as 30 psf. :) He does look like you.

Thanks Inspector D This seems like it will really affect the load bearing capacity of my floors though. Do you have any idea of what psf load these could take? I can only find load bearing formulas for newer joists that connect at the bottom.

No, it is about 15 years old. I bought it about 3 months ago.

Thanks ToolGuy. Yeah they are all like this, and it is a 3 story townhouse. This is the only exposed part that is behind the fire place. The rest is behind sheet rock.

I was inspecting my house to see what kind of load bearing my floors could take. I have an open joist system that uses 11.75" joists with 24" in-between them. When building the house, the contractor connected the joist to the wall by cutting back the bottom 2X4 so that it does not connect to...
