During the inspection, the property and it’s surroundings are inspected for conditions that indicate prior or future seismic and/or foundation concerns. Some of these items include structural defects that affect the performance of the property during an earthquake. Cal-Quake experts check for cracks in foundations, sidewalks, driveways, garage floors along with drainage concerns.
Water and soil conditions also create permanent foundation problems. Much of California is on clay or expansive type soils. Expansive soils act like a sponge. As they absorb water, they swell and as they lose water they shrink.
As the soil under a house shrinks and swells with the seasons, the foundation will move up and down. As the foundation moves, damage to the property and/or foundation becomes a problem.
When a property sits on a raised foundation on expansive soil, it experiences continual soil expansion and contraction. This causes normal “settlement” and usually leaves the floors higher in the center of the property.
If an owner wishes to stop seasonal property and foundation damage, a controlled watering program must be instituted. Keeping the moisture content of the soil under the foundation constant, foundation movement can often be stopped. CAL-QUAKE assists the property owner with performing a foundation preventive maintenance program.
