When I got to the office the other day, my boss was looking very stressed out.  I asked him what the problem was, and he told me that our basement had flooded, and he had spent the morning trying to get all of the water out.  I asked him if there was anything that I could do to help out, and he told me the only way that I could help was if I knew anything about exterior basement waterproofing.  I told him that I had actually trained with a waterproofing company for a while, so I did know a little bit about it.
