Hi,

I live in a condo in California, my CC&R's require that we have some type of sound barrier if we want to lay wood flooring. I bought the sound proofing, but now they say that there isn't enough concrete between the floor and I will need to find out what is the sound ration for slab concrete flooring by the inch...Can you help me out? I have paid and astronomical amount of money for my flooring which is sitting waiting to be installed....PLEASE HELP so I can give them an answer...I WANT MY FLOORS
