Yes, polyurethane foam can be used to stabilize a house foundation, though its application depends on the severity of the settlement and the specific soil conditions.
In many cases, polyurethane foam injection is used for slab stabilization and to fill underground voids, which restores integrity to sunken concrete surfaces like garage floors. It is particularly effective in Denver’s expansive clay soils because the foam is waterproof, lightweight, and resists moisture intrusion.
However, for more significant foundation issues, the following considerations apply:
Because foundation needs vary, a professional on-site inspection is required to determine if polyurethane foam alone is sufficient or if a combination of structural piers is necessary for long-term stability.
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…
