What Is a Slab Leak
A slab leak is a water leak that occurs in the plumbing lines located beneath a concrete slab foundation. These leaks can develop in hot or cold water lines and often go unnoticed until they cause damage or unusual symptoms inside the home.
Where Slab Leaks Occur
In homes built on concrete slabs, water pipes are commonly installed below the foundation. Over time, corrosion, shifting soil, or pipe defects can cause leaks under the slab.
- Hot or cold water lines beneath the slab
- Areas where pipes pass through concrete
- Sections exposed to soil movement or corrosion
Common Causes of Slab Leaks
Several factors contribute to slab leaks, especially in older homes or areas with aggressive soil or water conditions.
- Pipe corrosion or deterioration
- High water pressure
- Soil movement or foundation shifting
- Poor installation or aging materials
Signs of a Slab Leak
Slab leaks often present warning signs before major damage occurs. Early detection helps reduce repair costs and prevent structural issues.
- Warm or damp spots on floors
- Unexplained increase in water bills
- Sound of running water when fixtures are off
- Cracks in flooring or foundation
Why Slab Leaks Should Be Addressed Quickly
If left untreated, slab leaks can cause foundation damage, mold growth, and ongoing water loss. Prompt evaluation helps determine whether targeted repair or full repiping is the best solution.
Repair Options for Slab Leaks
Depending on the location and condition of the pipes, solutions may include spot repair, rerouting lines, or a complete repipe to bypass failing under slab plumbing.
