Plumbing leakage can cause serious foundation damage by disturbing the soil beneath your home. When water from leaking pipes seeps into the ground, it changes the moisture level in the soil, which can lead to foundation movement and cracks.
Here’s how it happens:
- Soil expansion or erosion
- In clay-rich soil, excess water from leaks causes the soil to expand, pushing up against the foundation.
- In sandy or loose soil, water can wash away particles, creating voids that cause the foundation to settle or sink.
- Uneven moisture levels
- Water leaking from one area creates an imbalance. Some parts of the soil may swell while others stay dry, leading to uneven settling or foundation cracks.
- Increased hydrostatic pressure
- Constant water buildup can create pressure against foundation walls, especially in basements, leading to bowing or cracking.
- Hidden damage
- Leaks under the slab (in slab-on-grade foundations) are hard to detect and can go unnoticed for months, causing gradual but severe foundation issues.
Even small plumbing leaks can weaken the soil and lead to costly foundation damage over time. Regular plumbing inspections and quick repairs can help protect your home’s structural integrity.
