6 Reasons Why Your House Is Settling: An Iowa Homeowner's Guide

As a homeowner in Des Moines, Iowa, the thought of your house settling can be a significant concern. While some minor settling is natural over time, excessive or uneven settlement can lead to serious structural issues, impacting your home's safety and value. At BAM Basements and Masons, Iowa's top-rated basement waterproofing and foundation repair company, we understand the unique challenges Iowa's climate and soil conditions present. With over 265+ 5-star Google reviews, we're here to help you understand why your house might be settling and what can be done about it.

Here are six common reasons why homes in Iowa experience settling:

1. Degrading Organic Material Beneath the Foundation

Often, during the initial construction of a home, especially in older neighborhoods or areas with previous development, organic materials like tree roots, mulch, sticks, or even construction debris might be inadvertently buried beneath the foundation. Over time, these materials naturally decompose. As they degrade, they create voids and pockets in the soil directly supporting your foundation. This loss of support causes the foundation to sink into these newly formed spaces, leading to settlement. In Iowa, with its rich agricultural history and varied landscapes, it's not uncommon for such organic matter to be present in the soil, making this a relevant concern for many homeowners.

2. Improper Soil Compaction and Backfilling

Before a foundation is poured, builders must excavate the ground to create a level and stable base. If too much soil is removed, it must be replaced and properly compacted. The key here is properly. If the soil is not adequately compacted before the foundation is laid, it will inevitably settle over time under the immense weight of the house. This is particularly critical in Iowa, where seasonal freeze-thaw cycles can exacerbate poorly compacted soil, leading to more pronounced and rapid settlement. A foundation built on loosely packed soil is destined for problems, as the soil will continue to compress, causing the house above to sink unevenly.

3. Neglecting Existing Soil Conditions: The Iowa Clay Factor

Iowa's geology often includes significant deposits of expansive clay soils. These soils are notorious for their ability to absorb large amounts of water, causing them to swell and expand dramatically. Conversely, when they dry out, they shrink considerably. This constant cycle of expansion and contraction puts immense stress on your home's foundation. Builders who fail to account for these expansive soil conditions during the planning and construction phases set the stage for future settlement issues. The fluctuating moisture levels common in Iowa, from wet springs to dry summers, make homes built on expansive clay particularly vulnerable to this type of foundation movement.

4. Inadequate Drainage Around the Foundation

Water is one of the most destructive forces for a home's foundation. If your property lacks a proper drainage system, rainwater and snowmelt can accumulate around your foundation. This standing water can saturate the soil, reducing its load-bearing capacity, or worse, wash away the soil entirely from beneath the foundation. This erosion creates unsupported areas, leading to localized settlement. In Iowa, heavy rainfall and significant snow accumulation are common, making effective gutter systems, downspout extensions, and proper grading around your home absolutely essential to protect your foundation from water-induced settlement.

5. The Impact of Tree Roots

While trees add beauty and value to a property, their root systems can be a double-edged sword for foundations. Large tree roots can grow directly under a foundation, exerting upward pressure that can lift and crack the concrete. Alternatively, during dry periods, extensive root systems can aggressively draw moisture out of the soil around and beneath your foundation. This desiccation causes the soil to shrink, leading to a loss of support and subsequent settlement. Homeowners in Iowa with mature trees close to their homes should be mindful of this potential issue and consider professional landscaping advice.

6. Soil Creep (Downhill Creep)

Soil creep, also known as downhill creep, is a slow, gradual movement of soil down a slope. This phenomenon can exert significant lateral pressure against your foundation, pushing it out of alignment or causing it to settle unevenly. While often associated with large geological areas, even subtle slopes on a property can experience soil creep, especially in areas with loose soil and consistent moisture. In Iowa's rolling terrain, particularly after periods of heavy rain or snowmelt, soil creep can be a contributing factor to foundation problems, leading to a gradual but persistent settlement over time.
