Poor drainage is a leading contributor to foundation settlement because it disrupts the stability of the soil supporting a structure. When water is not properly routed away from a home, it saturates the ground, leading to two primary destructive processes:
Saturated, waterlogged soil can erode over time. When water pools near the foundation due to improper grading, clogged gutters, or short downspouts, it can wash away fine soil particles from under the footings. This creates hidden voids, leaving the foundation without adequate support and causing it to settle unevenly.
In regions with expansive clay soils, such as Colorado, poor drainage is particularly damaging. These clays swell dramatically when saturated and shrink as they dry. This cyclical movement creates a back-and-forth stress that weakens the foundation’s integrity. Additionally, loose fill soil that was not properly compacted during construction will compress further when it becomes saturated, accelerating the settlement process.
Warning signs of drainage-related settlement include:
Whether a crack is structural or cosmetic depends largely on its orientation, width, and accompanying symptoms. While we often see vertical cracks that are purely cosmetic—resulting from the natural drying and shrinking of framing lumber—diagonal cracks at a 45-degree angle…
Distinguishing between normal settling and serious foundation movement involves looking at the size, direction, and surrounding symptoms of the cracks. While minor hairline cracks are a common part of a home’s “bedding-in” process, specific patterns often indicate a deeper structural…
In a new build, diagonal drywall cracks above door frames are a common occurrence, but their significance depends on their size and behavior. During the first year, framing lumber naturally dries and shrinks, and the foundation undergoes a “bedding-in” process.…
Seeing cracks in a brand-new home can be concerning, but it is important to distinguish between normal settling and structural distress. In new construction, framing lumber naturally dries and shrinks over the first year, which can produce minor hairline cracks.…
Diagonal drywall cracks above door frames are a classic indicator of differential foundation settlement. These cracks typically form at the upper corners of door frames—which are natural structural weak points—when one part of the foundation sinks or shifts more than…
