More important than 4 vs. 8 inches is the actual waterproofing installation itself, which you will no longer see once it is buried with earth, and will cost a ton of money to fix if it fails. First, the installation must be done correctly per the product manufacturer's recommendations and, second, the back-filling of earth must not be allowed to damage the installation. That said, 4" is fine and 8" is better.
