My mother's house sits on a cinder block foundation and brick wallls. The ground around this 1951 two-story bungallo is clay. She recently had her basement waterproofed and it began leaking again this past spring. When I took a closer look it appears the whole southeast corner of her house has stepped cracks leading from the center of the eastern and southern basement walls leading up, to just under the gutter of the southeastern corner. It appears as though the big maple tree about 15 feet away is drawing moister out of the clay cause it shrink away from the house. I believe the footings beneath the eastern and southern foundation walls have broke and now this corner is free from the house. In desperation I instructed her (against all intuition) start waterting the ground around this corner in an attempt to rehydrate the soil. This has had some success and the eastern cracks have closed very slightly. This can't go on much longer so does anyone have any advice?
