Few things are more alarming for homeowners than discovering a sudden depression or sinkhole forming in their yard. At AWS, we’ve inspected many properties where what appeared to be a simple low spot was actually the result of long-term water movement beneath the surface. In our experience, drainage issues, soil erosion, deteriorating underground pipes, and poorly compacted fill are among the most common causes of unexpected ground settlement. Identifying the source early is essential, as the visible depression is often only a symptom of a larger issue developing.
What may start as a small low spot can quickly grow larger, creating safety hazards, damaging landscaping, and potentially indicating a more serious underlying issue. While not every depression is a true sinkhole, any unexplained settling in your yard should be investigated to determine the cause. Understanding what causes sinkholes and depressions to form in your yard can help homeowners address problems early and prevent costly property damage. Our waterproofing experts at AWS have all the information you’re looking for.
What’s the Difference Between a Sinkhole and a Yard Depression?
Although the terms are often used interchangeably, sinkholes and yard depressions are not always the same thing. A sinkhole typically occurs when the ground beneath the surface begins to collapse due to erosion, water movement, or the dissolution of underground materials. True sinkholes can develop gradually or appear suddenly.
A yard depression, on the other hand, is often caused by settling soil, poor drainage, buried debris, or other localized issues. While depressions may not pose the same risks as a large sinkhole, they can still indicate drainage problems that need attention.
Poor Drainage and Water Erosion
One of the most common causes of yard depressions is poor drainage. When water repeatedly collects in certain areas, it can slowly wash away soil beneath the surface. Over time, this creates voids that eventually cause the ground above to sink.
Several drainage-related issues can contribute to this problem, including:
- Downspouts discharging too close to the home
- Standing water after storms
- Poor grading around the property
- Clogged or damaged drainage systems
- Excessive groundwater movement
As water continues to erode soil beneath the surface, noticeable low spots may begin to form throughout the yard.
Decaying Organic Material Underground
In some cases, depressions form because organic materials buried beneath the soil begin to decompose. When homes are built, construction crews may remove trees, stumps, roots, or other vegetation. If some of this material remains buried underground, it will eventually rot away. As the organic material breaks down, empty spaces are left behind, causing the soil above to settle. This process can take years, which is why homeowners may notice depressions long after a home has been constructed.
Buried Construction Debris
Construction debris can also contribute to yard settling. Pieces of lumber, drywall, concrete, and other materials are sometimes buried during construction or landscaping projects.
As these materials deteriorate or shift over time, the soil above may begin to sink. This often creates isolated depressions that continue to worsen unless the underlying void is properly filled and stabilized.
Broken Underground Pipes
Damaged water lines, sewer pipes, or drainage pipes can create significant soil erosion beneath your property. Even a small underground leak can wash away surrounding soil over time.
Signs of an underground pipe issue may include:
- Unexpected wet spots in the yard
- Increased water bills
- Areas of unusually lush grass growth
- Recurring depressions in the same location
Because underground leaks can cause extensive damage, they should be addressed as soon as possible.
Natural Soil Settling
Not all depressions indicate a major problem. In many cases, soil naturally settles over time, particularly in areas where fill dirt was added during construction. While minor settling is normal, larger depressions or areas that continue to deepen may suggest a drainage or erosion issue that requires professional evaluation.
Warning Signs You Shouldn’t Ignore
Homeowners should monitor any unusual changes in their landscape. Common warning signs include:
- New holes or depressions appearing after rainfall
- Standing water that wasn’t previously present
- Cracks in patios, sidewalks, or driveways
- Soil pulling away from foundations
- Areas of sinking or uneven ground
Early intervention can often prevent a small problem from becoming a much larger repair project.
How AWS Can Help
Determining the exact cause of a sinkhole or yard depression isn’t always easy. In many cases, the issue is tied to drainage problems, soil erosion, or underground water movement that requires professional attention.
