When homeowners reach out to us for foundation repairs, many want to know why these problems have suddenly begun to manifest themselves. This post provides a brief overview of the most common reasons a home will sink, settle, or sag, when it may have appeared perfectly find for years.

Shrinkage

If you live in an area that’s extremely arid and/or prone to drought, the soil on which your home is built may be at risk for shrinkage. When certain types of soil become completely devoid of water, they shrink, creating empty space beneath and around your foundation. Eventually, the weight of the house will cause the foundation to settle into these unsupported areas. Shrinkage can also occur on properties with lots of mature trees that drain moisture from the soil.

Softening

The opposite of soil shrinkage due to lack of moisture is soil softening due to excess moisture. If you live in an area where heavy rain and/or floods are the norm, this could weaken the load-bearing capacity of the soil. Over time, the tremendous weight of a home can cause the entire foundation to shift and sink into the ground. Properties that have poor drainage can also experience this problem over time.

Poor Compaction

In order to create level ground for new construction, a developer may remove earth from nearby hilltops and deposit it into the valleys. If not compacted sufficiently, this process will almost always result in soil settlement that presents a danger to your foundation.
