Your home may appear steadfast, but beneath the surface lies a dynamic relationship between soil and structure. The moisture content of the soil surrounding your foundation plays a pivotal role in its stability. Just like Goldilocks and her porridge, the soil needs to be “just right” – not too wet, not too dry. At Hargrave Custom Foundation Repair, we’ve witnessed the detrimental effects of unbalanced soil moisture firsthand. Let’s delve into how this hidden enemy can impact your home’s foundation and what you can do to protect it.
The Expansive Clay Conundrum: Too Much Moisture
In regions with expansive clay soils, like many parts of Texas, excessive moisture can wreak havoc on foundations. These clay soils have a unique ability to absorb large amounts of water, causing them to swell and exert immense pressure on your foundation. This can lead to:
- Foundation Heave: The upward movement of the foundation, causing cracks, uneven floors, and doors that stick.
- Slab Cracking: The pressure from expanding soil can cause cracks in concrete slab foundations.
- Basement Wall Damage: Basement walls can bow or crack under the strain of expansive soil.
The Shrinking Soil Syndrome: Too Little Moisture
On the flip side, drought conditions can cause the soil around your foundation to shrink and pull away. This creates voids beneath the foundation, leading to:
- Foundation Settlement: The downward movement of the foundation, resulting in cracks, sloping floors, and doors that won’t latch.
- Pier and Beam Issues: In pier and beam foundations, the wooden beams can become exposed and susceptible to rot when the soil shrinks away or when water stands in your crawlspace for long periods of time.
The Water Damage Wildcard: Plumbing Leaks and Poor Drainage
Even in areas without expansive clay, poor drainage and plumbing leaks can saturate the soil, causing instability and damage. Excess water can erode the soil supporting your foundation, leading to settlement or shifting. Additionally, water intrusion can weaken concrete and lead to cracking.
Striking a Balance: Maintaining Optimal Soil Moisture
The key to a stable foundation is maintaining consistent soil moisture levels. This involves:
- Proper Drainage: Ensure your gutters and downspouts are functioning correctly and directing water away from your foundation.
- Grading: Ensure the ground slopes away from your home to prevent water from pooling near the foundation when possible
- Landscaping: Choose plants with shallow root systems and avoid overwatering.
- Address Plumbing Leaks: Fix any plumbing leaks promptly to prevent water damage.
- Watering During Droughts: In dry periods, strategically water around your foundation to prevent soil shrinkage. In the Dallas/Fort Worth area soil shrinkage is the primary cause of foundation problems.
