Can Armadillos, Moles, and Gophers Damage Your Foundation?
Most East Texas homeowners know their foundation faces real challenges from expansive clay soils, fluctuating moisture, and the region’s unpredictable weather patterns. But there is another threat that often goes unnoticed until the damage is already done, and it is living right in your yard. Armadillos, moles, and pocket gophers are common throughout East Texas, and their burrowing activity beneath and around your home can quietly compromise the soil that your foundation depends on for stability. At Barwell Solutions, we have spent years helping homeowners across Tyler, Lindale, Athens, Gilmer, and the surrounding area address foundation problems at their root cause, not just their symptoms. Our geo-tech team understands that healthy soil is the foundation of a healthy foundation. We bring honest assessments, proven stabilization techniques, and a genuine commitment to protecting your home from the ground up. If something is burrowing around your home, here is what you need to understand and what to do about it.
How Burrowing Animals Compromise Soil Stability and Create Foundation Risk Beneath Your Home
The concern is not that an armadillo or mole will crack your slab directly. The concern is what their activity does to the soil over time. East Texas’s sandy loam soils, which make burrowing so easy for these animals in the first place, are also the soils most vulnerable to the secondary effects of tunnel systems beneath and around your home’s perimeter.
The Three Common Culprits in East Texas Yards
Understanding which animal is active on your property helps you understand the specific risk it poses.
Armadillos are perhaps the most significant foundation concern of the three. The nine-banded armadillo is the state’s official small mammal and is found throughout East Texas in abundance. Armadillos specifically tend to burrow against solid structures, including home foundations, pool decks, and porches, because these structures provide a stable overhead ceiling for their burrow systems. Their tunnels can reach considerable depth and length, and when those tunnels run directly beneath a foundation or slab edge, they create voids in the supporting soil that can allow water to pool, channel, and erode the ground beneath your home.
Pocket gophers are active throughout East Texas and are capable of creating extensive tunnel networks that collapse and cause erosion beneath structures. Unlike armadillos, gophers are primarily root eaters, which means their tunneling can also damage drainage infrastructure and landscaping that helps direct water away from your foundation. Gopher tunnels tend to run deeper and larger in diameter than mole tunnels, making the void risk more significant.
Moles create two types of tunnels: shallow surface runs used for feeding, and deeper highways used for travel between nesting areas and food sources. Research from Texas Tech University documented a single mole burrow in Van Zandt County that ran nearly a quarter of a mile in length. In East Texas, where the sandy soil makes burrowing especially easy, mole tunnel systems beneath a home’s perimeter can disrupt soil density and allow water pathways to form in areas where drainage should flow away from the structure.
How Burrowing Activity Creates Foundation Risk Over Time
The direct risk from any single tunnel is generally manageable. The risk that compounds over months and years of unaddressed burrowing activity is a different matter entirely. Here is how the progression typically works:
Tunnel systems create voids and reduced soil density beneath and beside the foundation. Those voids become pathways for water during heavy East Texas rain events, channeling moisture into areas where it would not otherwise reach. Water intrusion beneath a slab or around foundation piers softens and destabilizes the soil, reducing its load-bearing capacity. As soil shifts and settles unevenly, the foundation above begins to move with it.
East Texas already presents challenging foundation conditions due to its clay and sandy loam soil composition and the region’s cycle of wet winters, heavy spring rains, and dry summers. Burrowing pest activity is an accelerant on top of those existing stressors. The homeowners who call us after years of dismissing armadillo holes near their foundation often discover that what began as a nuisance has contributed meaningfully to soil conditions that now require professional remediation.
What to Watch For Around Your Foundation
You do not need to wait until foundation symptoms appear inside the home to take action. These exterior warning signs often appear first and should prompt a call to a foundation professional:
- Cone-shaped or tunnel-shaped holes along the perimeter of your foundation, under porches, or beside exterior walls
- Raised ridges or soft spots in the soil close to the house that indicate subsurface tunneling
- Unexplained soft or sunken areas in the soil near your slab edge or pier locations
- Water pooling near the foundation after rain in areas where it previously drained away normally
- Fan-shaped mounds of displaced soil appearing repeatedly near your home’s perimeter
Each of these can indicate active burrowing that warrants inspection before any existing foundation vulnerabilities are made worse.
How Barwell Solutions Addresses the Soil Damage Left Behind
Removing the pest is only the first step. The soil damage and voids they leave behind require professional attention to ensure the foundation above is not sitting over compromised ground.
Barwell Solutions uses our geo-tech soil stabilization system to permanently fill voids, seal gaps, and fortify the soil beneath and around affected areas. Our environmentally safe injection process reaches below the surface without the disruption of excavation, stabilizing the soil structure and eliminating the pathways that allow water to migrate under the slab or around foundation piers. We also evaluate drainage conditions around the entire perimeter of your home, because burrowing activity near the foundation is often a sign that other moisture management issues deserve attention at the same time.
Every assessment we perform starts with honesty. We will tell you exactly what we find, what it means for your foundation, and what, if anything, needs to be done. We will never recommend work your home does not need.
