Frequently asked questions
The block wall shows a wet line after every May storm. Is the block failing?
The block is doing what block does in wet clay. Concrete block is porous and the mortar joints more so, and when the red clay outside is saturated the water moves through the wall and shows as a line at the level the ground is wet to. Sixty-year-old walls have done this for decades. What has usually changed is the footing drain, clay tile that has likely collapsed, so the water now sits against the wall rather than draining.
Our split-level has a damp lower floor but a dry upper one. Why the difference?
The lower floor sits in the ground. A split-level puts that level three or four feet below grade in clay that is wet from winter through spring, so its walls touch saturated soil on the outside while the upper floors are in the air. In May, with the ground at its wettest, the lower floor is effectively a shallow basement without a basement's drainage. Treating it as one, with grading and a drain, does more than treating symptoms inside.
The trees are the best thing about the street. Are they part of the water problem?
They are, in two ways. The trees planted when these houses went up are now large enough to shade the foundations completely, so the clay against the walls never dries out between storms. Their roots also seek out the footing drains, and a clay tile drain from the 1960s with a root in it is a blocked drain. Neither means removing the trees; it means the drainage those trees have disabled has to be replaced by something they cannot reach.
