Why Concrete Settles More in Late Summer

Late summer in Denver often brings dry spells and high heat—two major factors behind concrete settling. While this can happen year-round, the seasonal mix of compacted soil and lack of moisture during August and September speeds up the problem. What seems like a harmless crack can quickly lead to sinking slabs and uneven surfaces.

The cause? Dry, shrinking soil. As moisture evaporates from the ground, the soil beneath your concrete contracts, leaving gaps. Without stable support, the concrete sinks—creating trip hazards and drainage issues that only get worse if left untreated.

Common Signs of Concrete Settling

Catching the early signs can save time and money. Here’s what to look for:

These red flags often start subtly but can quickly worsen, especially if ignored through the fall and winter months.

How Dry Soil Impacts Foundations

In Denver’s clay-rich soils, hot and dry late-summer conditions cause significant ground shrinkage. When this happens, concrete slabs—and even parts of your foundation—can shift or sink unevenly.

Here’s how it can affect your property:

Structural Movement: Cracks may appear in basement walls or garage floors

Improper Drainage: Water runoff flows toward your foundation instead of away

Increased Risk: Sunken sidewalks create hazards for guests, tenants, or customers

How to Fix Late-Summer Settling

The good news? You don’t need a full concrete replacement. Concrete lifting (also called mudjacking or slabjacking) is a cost-effective and minimally invasive way to raise sunken slabs.

Benefits include:

  • Fast turnaround with minimal disruption
  • Restores level, safe surfaces
  • More affordable than replacement
