Tree Roots and Foundation Problems… Could You Be Growing A Problem?
The impact of tree roots on concrete slab foundations is a controversial subject. In our experience tree roots cause substantial foundation damage in North Texas.
Tree roots can extend as much as 5 times the canopy height of a tree. In periods of drought, tree roots seek out water.
According to Dr. Tom Witherspoon, if the soil under your foundation is more moist than the soil outside, the tree roots will seek out the water from under your house. As the moisture content drops, clay soil shrinks, and the foundation support in that area is reduced. The net result is foundation failure and the need for foundation repair.
