Just so you know i`m training to be a home inspector and haven`t read anything on this subject topic as yet.But in my work history these are things I`ve spotted over the years.Please feel free to comment on each scenario.Some are obviously simple and some are tricky! Here are some basement foundation wall systems i`ve encountered.How would a home inspector write these up,thats assuming he can determine how they were built....and all things being equal.[i know that you just do visual inspections so lets just assume there is a section without drywall.]I`m in Canada,so its a northern climatic region.

Note...Since I found out about the building science engineers not using a vapour barrier its made me rethink things.
