I'm a bit puzzled about what's behind the drywall in my high rise condo built 3 years back. When drilling into an interior room wall supposedly where a stud should be(found by a stud detector and yes I am using it properly), my drill goes through the wall with barely any resistance.
It's a fairly lengthy wall, about 10 feet connecting my living room to my bedroom. However, when I drill into the wall connecting to the neighbours, I feel a lot of resistance and definitely hitting a stud.
Could it simply be that the studs are paper thin and weren't meant to handle extra load besides the wall?
