Foundation movement comes in varying degrees. An experienced professional should be consulted to assess the movement to determine the severity and provide remediation solutions as may be required.
To fully appreciate how foundation movement can be remediated, one must understand the cause of the movement. Foundation settlement and movement can be caused by one or a combination of the following:
There are other causes for foundation movement, but the above five are the most common. Once again, it is very important that all relevant information be analyzed by an experienced professional to determine what is occurring. Only then can an effective remediation plan be put together.
One of the most common solutions to stabilize the foundation of a building is to underpin the foundation down onto a more stable soil. This soil layer should be suitable by strength and type to accommodate the loads exerted on it. It should also be well below the “active soil layer”.
“Active Soil Layer” is the layer of soil that is affected by seasonal changes in moisture levels. Most commonly this soil layer is within the top 20 feet of soil. Periods of drought or high periods of precipitation can drastically affect expansive clay or sensitive soils.
Underpinning is typically done by installing a pile under the existing foundation. There are many forms of piles available.
