Concretemasonry and Taro, thanks for your response, however the 6 mil is already installed. I need to know if there is any data indicating the life expectancy for the 6 mil versus the 10 mil.
This is considering both products are installed under the same field conditions.
I am constructing a four story townhouse project in Georgia. I have been told by the Architect that a 6 mil vapor barrier shall deteriorate over time allowing water to seep through the cocrete and damage the finish floor. In lieu of a 6 mil barrier I should use a 10 mil barrier.
1. How long...
