Why Concrete Patios Sink in Lakewood, CO and How Foam Jacking Can Help

What Causes Concrete Patios to Sink?

Concrete patios depend on the soil and base materials underneath them for support. When those materials shift, compress, or wash away, sections of the slab may lose support and gradually settle. Several factors can contribute to this movement.

Changes in Soil Moisture

Colorado has areas with expansive soils that change volume as moisture conditions fluctuate. Certain clay-rich soils expand when wet and shrink as they dry. These movements can affect the support beneath concrete surfaces. Lakewood properties may experience different soil conditions depending on their location, construction history, and drainage characteristics. Not every uneven patio is caused by expansive soil, so identifying the actual source of movement is important before choosing a repair method.

Poor Drainage Around the Patio

Water that repeatedly collects beside a concrete slab can contribute to erosion and changes in the supporting soil. Downspouts that discharge near the patio, improper grading, and concentrated landscape irrigation may increase moisture around vulnerable areas. Over time, the supporting material can weaken or develop voids, allowing portions of the concrete to settle.

Compacted or Settling Fill Material

Patios built over disturbed or inadequately compacted soil may experience movement after installation. As the underlying material compresses, the slab can gradually drop, sometimes creating a noticeable height difference between adjacent concrete sections.

Warning Signs Your Patio May Need Concrete Leveling

Patio settlement doesn't always happen suddenly. Many homeowners first notice small changes that become more obvious over time.

Watch for these common indicators:

• One corner of the patio sits lower than the surrounding concrete.

• Rainwater collects in depressions instead of draining away.

• A gap develops between the patio and nearby structures.

• Outdoor furniture rocks because the surface is uneven.

• Adjacent concrete sections have different elevations.

• Existing cracks appear to change as settlement continues.

These signs suggest that a closer inspection may be worthwhile.

How Does Polyurethane Foam Jacking Work?

Foam jacking is a concrete lifting technique that uses expanding polyurethane material to raise suitable settled slabs. Instead of removing the existing patio, a contractor drills small injection holes through the concrete. Specialized equipment delivers polyurethane beneath the surface, where it expands into available spaces. As the material fills voids and develops controlled pressure, it can lift the concrete toward the desired elevation. The contractor monitors slab movement and adjusts the injection process based on the condition of the patio. Once lifting is complete, the injection openings are patched. The process may avoid the extensive demolition associated with replacing an otherwise sound concrete patio.

Is Foam Jacking Better Than Replacing a Patio?

The most appropriate repair depends on the condition of the concrete and what caused it to move. Foam jacking may be worth considering when the patio remains largely intact but has settled because of lost support beneath the slab. Replacement may be more suitable when the concrete is severely broken, crumbling, extensively deteriorated, or affected by conditions that lifting cannot reasonably correct. Foam jacking also does not repair existing surface damage or permanently eliminate unresolved soil and drainage problems. A professional assessment helps determine whether lifting the existing patio is practical.

Why Lakewood Homeowners Should Address Patio Drainage

Water management is especially important when evaluating settled outdoor concrete.

If water continues flowing toward an area with weakened support, additional movement may occur even after the slab is lifted. Depending on the property, solutions might include adjusting downspout discharge locations, addressing landscape drainage, or correcting other sources of excessive moisture. These improvements should be evaluated separately from the concrete lifting itself.
