Structures built on unstable soil can cause different problems with your foundation.  This could be a geographic trend in the area, or the structures relation to a river or lake.

Most foundation repair is needed because of soil-related problems. Moisture content in soil changes with the seasons. This can shrink heavily concentrated clay soil, which reduces the support under existing footings. Poor compaction, organic materials in the soil and overloading can also cause failure.  Seasonal and climatic changes also affect your structure’s foundation. Don’t wait for more costly damages to occur.
