My house was built in the late 1960s and has the original wooden parquet flooring in the lounge, dining room and hallway. As far as I can tell the house has a proper damp proof course, which is below the screed on which the parquet floor has been glued using what appears to be a thin layer of bitumen glue: so it does not seem that my wooden parquet floor with its bitumen glue is intended to act as a damp proof course.
Currently I am planning to put underlay (probably Cloud 9 Cirrus) and carpet down on top of the wooden parquet flooring. I am considering choosing a carpet that is 100% polypropylene, as I like the colour options available and the stain resistance and stain protection aspects of polypropylene carpet. However, I am wondering if a carpet that is 100% polypropylene is suitable for laying on underlay on top of a wooden parquet floor. I am querying this because I have seen a couple of reports on the Internet of wooden parquet floors ‘buckling’ when a polypropylene carpet has been laid on top of them.
I should be grateful for any advice.
