A building’s foundation and related structural framing are critical to the support of a structure. The foundation ultimately transfers the entire building load into the underlying, supporting soil.

A poorly constructed or deteriorated foundation can cause damage to:

• Interior and exterior walls;
• Flooring;
• Cabinetry and countertops;
• Doors and windows;
• In more extreme circumstances, the structural integrity of the home or commercial building itself.

In addition to the perils of a substandard foundation, problematic soil beneath an existing foundation can cause these same problems. The San Francisco Bay Area is world renowned for its soil issues. Some of these include:

• Expansive soils;
• Weak soil deposits;
• Poorly consolidated fill soil;
• Dune sands;
• Marine deposits;
• Landslides;
• Slope creep;
• Earthquakes.
