Foundation Problems
Causes of Foundation Problems – Why Is This Happening?
Unstable Ground or Poorly Compacted Soil: If soil isn’t compacted correctly during construction, it can settle unevenly, causing foundation shifts and cracks.
Expansive Soil Types: Certain soils, like clay, expand when wet and shrink when dry, leading to shifting and cracks in the foundation.
Improper Grade & Storm Water Runoff: Poor grading around a home can allow water to pool around the foundation, eroding soil and weakening the structure.
Poor Foundation Construction: Inadequate rebar placement or poorly built footings result in a foundation that can’t withstand soil pressure and environmental changes.
Large Trees and Shrubs: The roots of large plants can encroach on foundation walls, displacing soil and creating cracks or shifts.
Adobe Soils: Adobe soil, common in the Bay Area, consists of expansive clay that doubles in size when wet, causing foundation upheaval or sinking as moisture levels fluctuate.
Seismic Activity: Frequent tremors in our region can shift foundations, leading to cracks and long-term weakening.
