With time even the strongest foundation can fail, because of poor soil preparation or just poor soil underneath the existing foundation. Not all soil types are equal, some are more suitable for supporting foundations than others. You can obtain soil boring test as a homeowner but those are very expensive and may run in the thousands depending how many holes are being bored. They would tell you what you already know, the soil underneath your foundation is failing to support your foundation.
Main Causes of Foundation Failure
- Evaporation –In very dry conditions, clay soils (which are common in the Chicagoland area) can shrink, leaving gaps beneath your foundation. Without adequate support, the foundation begins to settle and sink. Even after the dry conditions pass, the foundation sinking will continue unless addressed.
- Grading Problems – Poor grading around your home can lead to excessive water pressure pushing against the foundation, causing it to bow inward. Over time, this lateral pressure can weaken your foundation and lead to failure.
- Drainage Problems – Improper drainage from rain gutters can cause water to pool around your foundation. This excess moisture makes the soil beneath your home expand, which can result in foundation failure as the shifting soil pushes on the structure.
- Unsuitable Soil Conditions – Soil that hasn’t been properly compacted during construction can expand and contract over time, leading to foundation settlement. This unstable soil condition is a frequent cause of foundation issues.
- Trees and Roots – You may not realize it, but trees planted too close to your foundation can cause significant damage. Tree roots can dry up the soil near your foundation, leading to settlement, or they can exert lateral force on your foundation, causing it to crack or bow inward.
- Plumbing Leaks – A hidden plumbing leak can slowly erode the soil under your foundation for years before it's noticed. The moisture from the leak adds pressure to the foundation, potentially leading to cracking or failure.
- Foundation Not Secured – If a foundation isn't properly secured to the floor frame during construction, it may begin to lean or shift over time, which can result in structural instability and eventual foundation failure.
