Foundation shifting is a natural stage of a settling foundation. “Shifting” refers to the sinking movement of a foundation into the ground as its immense weight settles. In the first few weeks of being built, a foundation will experience “uniform settlement” which is when the entire foundation shifts together the same amount.
However, issues arises when a foundation begins to experience “differential settlement”, which is when certain parts of the foundation are shifting more or less than others. Factors such as heavy rainfalls, improper yard grading, clogged downspouts, plumbing leaks, expanding and contracting soil, and frost heave all cause foundations to shift unevenly. Over time, even the smallest differential foundation movement can cause significant problems that will require foundation repair.
