I want to know the answer to the following question:
In what places were asphalt used as waterproofing?
All the background I'm provided with is that "For example, asphalt could also used for flooring, damp proofing in buildings, and for waterproofing of various types of pools and baths, with these latter themselves proliferating in the 19th century.". Is that enough to answer the question?
Answer: yes
