Drilling into concrete foundation to install TV Frame Mount?
 
Hello everyone, I'm new to the forums and looking for some advice.

I'm wanting to mount my 42" Plasma TV to a wall in my basement. The basement is finished BUT the people who framed the basement put the 2x4's in the wrong way. Instead of having 4 inches between the drywall and foundation, I only have 2 inches.

I'm wanting to know if it would be safe to drill into the foundation, install some anchors and screw my TV to the wall? The screws are about 3 inches long, so I will only have to drill, at most, 2 inches into the foundation. My major concern is leaks. Should I do this or should I go through my wall and fix the 2x4's?

Thanks

Unpressure treated 2 X 4's never should have been installed in direct contact with concrete.
Since it's already up I'd just use 2-1/2 screws.

Leaks won't be an issue--the foundation is 8 inches thick----but you can't screw into the foundation and have the screws going through 2 inches of air before you attach the mounting plate--

Either open the drywall and add some solid wood blocking---or relocate the bracket to some of the existing blocking.

is the wall a full wall,floor to ceiling? if full wall mount the brackets to the studs, probably no need to go into concrete...

I was planning on still going through the studs. It's good to know that I can do that without having to tear my wall apart.

Yes the wall is a full wall. It's in my basement. In other words, we don't have a "walk-out" basement.

Concrete.... whatever type of concrete was used back in 1978.

I couple of holes shouldn't be a big deal. Certainly don't want to go all the way through.

Or similar.

If the 2x4 wall was framed wrong to start there is a good chance the studs are not secured properly to take the weight of you TV. To be safe I would add a few 3-1/4" x 3/16" tap-cons through the drywall and 2x4's into the concrete foundation in the location you plan to mount the TV. You are then good to go with mounting the TV bracket to the studs only with 2" # 10 pan head wood screws.
