Thanks Rob, Unfortunately we closed on the house already in oct 2005. When, our inspector inspect the crawlspace it was fairly dry except for small amount of standing water towar the back of the crawl space (of course rainy season doesn't start after we moved in). In november when it started rainning, my crawl space had 2.5 inch standing water and it doesn't receded even after period of no rain for 10 days. I felt that the water table is high and the water somehow enter the crawl space very readily. As a background. The house is build on a clay soil not too far from a large pond. the builder compacted 4 inches of gravel below the foundation. I am enclosing the picture of the lot while they are excavating and my house is the same level with the neighbor to the side Download Attachment: Stuman4.jpg 54.9 KB On the next picture you can se how high the house is above the street which really puzzle me why we have water problem and the drain from the crawl space but I believe may not placed at the lowest point in the crawl space because water will accumulate in the crawl space but never any higher that 2.5" because it drain to the street. But I still feel there is a proble if the water enter the crawl space whenever it rain. I know it's not the gutter because the gutter go to the drain around the house the drain to the street.
