I own a newer house (built in 1994) with a partial basement and crawl space. The crawl space is pretty typical-dirt flour about 3 feet higher than the rest of the basement, with a vapor barrier. The past two springs I had some flooding the crawl space after heavy precipitation. After last year's problem (which was pretty bad), I made sure that the vapor barrier was pulled up along the walls of the crawl space. I also added a bit more grade to the outside of my house to improve drainage (my downspouts all appear to be working fine). Unfortunately, I still got some standing water this spring. It wasn't nearly as bad, however, especially considering we got 20 inches of snow last week and a few inches of rain the past couple of days. I have noticed that the dirt under the vapor barrier is pretty saturated this time of year. My question is, should I just add more grade and check for rips in the vapor barrier, or are more dratic measures needed? I should note that while I haven't checked if there is a 5% grade away from the house, there is a definate slope.
