I recently purchased a home about 25 years old. I didn't realize it at the time but my crawl space has an uneven dirt flooring. There is evidence of busted up concrete around supports.(I am not sure if the crawl flooring was originally constructed of cement). A very thick gauge of plastic has been placed over the dirt flooring( the dirt loooks like clay, it's very hard). I would like some pro and con suggestions concerning covering the dirt floor with something more sturdy and to minimize the possiblity of insects. I would to like use the crawl for storage as there is no evident of water seepage. There are two vents located in different corners of the south wall. My living room and dining area is located above the crawl area.

Ok, I had a leaky basement. Cracks and efflourecence(sp) all over the place. I fixed the cracks. No problem. Cleaned the wall with bleach, and then with TSP. They were previously painted. I applied 2 coats of Benjerman Moore Fresh start. Alls good, until I strted to noitce that ine block in the bottom corner was turning a greenish yellow. Then I noitced thet all along the bottom row of block, the paint was Bubbleing, just in spots, scattered all over. The repairs I made are fine still. What caused this to happen and how do I fix it?
