We have a 1987 modular set on a concrete block foundation. We are shallow to bedrock, less than 3-4'. Our house is guttered into tile. We have water enter our crawl space with any major rain. I believe that it is simply ground water saturation due to the shallow to bedrock nature of our location. We have a buried LP gas tank and when you view the "access" neck it is also full of water. I am seeking a way to some how seal the crawl space off from the ground water level flucuations. The water has gotten high enough to saturated our heating duct work. I have yet to get any valid solutions to the problem. We have a sump pump partially installed, but when a flood event occurs the pump will run non-stop until the ground water level subsides. I would appreciate any and all recommendations. Thank you.

Having a house set on bedrock is often a difficult issue to fix. Cracks in the rock often can lead to water coming in. However, the footing of the crawl space is the lowest area of the structure. Digging down to that and installing a primeter drain should stop the water. Crawl space fixes are not any different then full basements. Just not as deep. What makes this a little more difficult is most likely the builder backfilled with the same stone and gravel that was dug out. Which in turn makes the digging a little harder. But this job can be done and most often then not it can be corrected.
