Correction for an uneven basement floor

I am jumping too in building my studio in my own basement. The slab is uneven starting a bit higher in the corners eventually dipping down about two inches toward the drain set in the middle. What are my options? I have obviously nobody under for it is a basement. Is a wood subfloor with styrofoam in between the 2x4's a possibility to even out the floor before putting a laminated floor ? Has anybody used the 2X2's press wood with ribbed rubber/plastic coating under as a subfloor ? Suggestions or comments are greatly appreciated Thank you

Find out if the drain is important - it was probably put in there for a previous owner. It would help if I knew where you lived - could you please fill out your location in your profile as per forum rules. There is a product called self-leveling concrete. It's slurry mixture that finds it's own level and then hardens to a normal concrete floor. http://www.edisoncoatings.com/html/Self ... loor_t.htm

The drain was there from the beginning. It is in the middle of the room, creating a slope of at most 2 inches from the edges. I would make sure the drain iremains free of access. But I would lose the slope around. Maybe keeping only a very slight one. I am about to have a french drain put in around the house. It should be fairly dry afterward!! The product you've suggested is interesting but I would think that it is only to fill irregularities in the cement rather than leveling a 2 inch slope?? Cheers Christian

It will do a 2" slope - they used heaps of it in the highrise building recently built near me as the whole structure was shifting in the sand as it went up - as a consequence all the floor were out of level when they finally bedded it down. It's not uncommon to fill over 2".

... the whole structure was shifting in the sand as it went up

:shock: Scary! I'm not sure I'd be interested in buying an apartment in that kind of building!!!! - Stuart -

:) this is the building Stuart :) I knew one of the contractors. It's the 19th tallest building in the world and the tallest residential building in the Southern Hemisphere.

Taller than the Eureka tower in Melbourne? 300m, 92 stories. Their still claiming that there're the tallest! :D

mmmmh to be precise; Q1 322,5 metres/1,058 feet 78 stories Completed: 2005 19th tallest building in the world Tallest all-residential building in the world and tallest building in the Southern Hemisphere

"The tower is the world's tallest residential tower when measured to its highest floor, but Q1 located on the Gold Coast is officially the world's tallest residential building as its spire adds to its total height" :D Boys and their spires!

doesn't impress me I'm afraid as I get vertigo in high buildings. I can't even stand a hotel room above the 10th floor :)

Well, yeah, but don't cry victory yet! Coming soon, to Santiago, Chile: 300m high, and in the Southern Hemisphere! :) http://www.plataformaurbana.cl/archive/ ... -paulmann/ It's under construction right now, and as far as I'm aware, it hasn't sunk into the sand yet! However, don't forget that Chile is a major earthquake area: I'd hate to be in that building for an earthquake.... It would bring an entirely new meaning to "rock and roll"... It's bad enough at ground level, and when I rented a place a few years back, on the ninth floor in an office building just a couple of blocks from where that monster is going up, we'd be swaying for several minutes after the quake was over. I think I'll skip these tall buildings in the Southern Hemisphere, thanks! John's is sinking and tilting, while ours will be bouncing and swaying! - Stuart -

300m is not going to be high enough to claim victory Stuart. ;) it's all bullshit anyway.

Ahh, but we can always put a spire on top! Or a TV antenna mast... It never ends, does it? There's always someone, somewhere, who just has to have one that's just a bit taller...

I am building a home recording studio in my basement. My budget is around 14 000.00$ Dimensions are : 15 X 28 It is an older home (1964). After having redone the french drain around the house, I want to put laminated wood on the cement slab. It has a total slope of 2 inches toward the drain in the middle. Can I build a wood subfloor, or should I even out the cement (leaving the drain free) then put 2 x 2 press wood squares with rubber underneath? Having obviously no neigbors underneath my challenges will be from the main floor above me After browsing through the commentaries concerning floating floors, I am somewhat confused about the complexity of it all Does it apply only to studio built on top of other people? or to my situation? Cheers

Doro, In your part of the world a basement drain is more of a requirement then an afterthought. The drain was installed for a reason that still exists. Your area of the world requires interior heating on a day-to-day basis that far out numbers somewhere in a warmer climate. With heat comes moisture. Add to that an exterior that is mostly frozen until some thaw takes place on a sunny day, now you have moisture on the exterior as well. Even if your walls are currently concrete, concrete can leak and absorb moisture. And if it is block, well, block and brick can hold moisture like a sponge! To answer your question on using wood products is difficult. But I can say with the utmost certainty that any type of pressed wood or composite type will break down if placed on this floor. I appreciate the french drain you are having installed and would ask that you make it known that you would like to have the exterior of your walls resealed against water if you have not already asked this. Any and all wood products that come in contact with this floor will always have the opportunity to come in contact with moisture, it is the nature of your situation. It may not be much and it may not be often, but the opportunity exists, is what I am meaning.

Wierd! :cop: follow the rulz Xspace

kick lil's but, X :mrgreen: (I'm just fooling around, ye know me)
