Raising a garage floor
I purchased a derelict (to put it nicely) house at auction here in Texas. A previous owner had enclosed the garage and turned it into a music room. However, he did not address the 1 1/2″ step up from the garage floor to the apron at the front. I want to eliminate the step as I plan to install a floating laminate wood floor over the entire room and then promote it as a home theater or game room during the sale.
I was thinking I could use 3/4″ treated sleepers 16″ OC followed by 3/4″ plywood. Is this the right approach? Someone suggested that I should pour concrete. I’m not sure I like that approach but I am willing to entertain the idea. What do you guys (gals?) think?
#1 question is how level is the existing concrete floor. at a minimum, you'll have to scribe or shim the sleepers.
I, myself would just pour a extra 1 2/3 of concrete. Then it would not leave a hollow for bugs to hide.
Shimming to level the floor is not a problem. What about a vapor barrier? And should I use felt or anything between the sleepers and the plywood?
given the chance to lay down a VB -Why wouldn't you? True the treated sleepers wont rot but what about the vapor coming up thru the slab itself and attacking the ply --try putting down a 2 foot square piece of poly tape down to seal and see it you have any vapor migrating thru the slab--We all know how concrete is the moisture super highway.
wait a minute i just saw you are from Texas right? Slab on grade? Maybe I'm throwing ####little up north info into a area that it doesn't apply. Well my box is creaking so I'd better get off before....aaahhhh to late. Mike
Hmmm, Breaktime at a loss for opinion? <G> Surely not!
If you use treated sleepers, there's no reason to use felt.
Whenever you are asked if you can do a job, tell'em "Certainly, I can!" Then get busy and find out how to do it. T. Roosevelt
