Many crawl spaces have moisture issues. A lot also get up to 3 feet of water that floods the crawl space. This is why it is so important to make sure before any crawl space issues are fixed we must ensure the crawl space has proper drainage. In this picture, you can see one way we make sure if any water enters the crawl space gets pumped out. We dig trenching where water would collect and install perforated pipe then fill it with rock. The pipe runs to a sump pump to be pumped a safe distance away from the home.
