Foundation problems may be affecting various parts of your home, and can be caused by several forces.
Backfill soil behaves differently than the unexcavated, “virgin soils” farther away from the foundation. Backfill soil typically absorbs more water and expands more, exerting pressure against the foundation.
The primary concern with foundations built on loamy soils is erosion. When soils underneath your foundation erode, they may begin to be inappropriate strata for sustaining the weight of a foundation and home structure.
