Hi,
We have just had a new polypropylene Inspection Chamber installed on our property. The chamber had to be situated within a new extension that is being built. Above the chamber will be a suspended wooden floor. The chamber has its own sealed cover to prevent smells from escaping into the property.
My question is: Is it necessary to install any additional cover above the chamber (either below or on the wooden floor) to prevent smells from escaping?
Cheers
