Tree Roots and Your Foundation
While it is a common misconception that tree roots grow directly into a concrete foundation, they can still cause significant damage indirectly.
-
Soil Desiccation: Large trees require a massive amount of water. Their roots can draw moisture out of the soil beneath your home, causing the soil to shrink and the foundation to settle or crack.
-
Upheaval: In some cases, roots growing directly under a shallow foundation can physically lift the concrete, leading to uneven floors and structural stress.
-
Expansion & Contraction: As roots grow and the seasons change, the constant removal and replenishment of moisture creates a cycle of soil movement that is highly detrimental to structural stability.
Plumbing Leaks: The Silent Threat
Plumbing leaks under a slab foundation (often called slab leaks) are one of the leading causes of foundation failure.
-
Erosion: A persistent leak can wash away the supporting soil beneath the slab, creating a void. Without proper support, the concrete will eventually crack and sink into the hole.
-
Hydrostatic Pressure: Excessive water buildup increases the pressure against the foundation. This can force water through tiny fissures in the concrete or even cause the foundation walls to bow or buckle.
-
Heave: When expansive clay soils become overly saturated by a leak, they swell with immense force, pushing the foundation upward and causing interior wall cracks and door alignment issues.
