A slab leak happens when a water pipe beneath your home’s concrete foundation breaks, leaks, or cracks. Since homes built on concrete slabs have pipes running under or through the concrete, any damage to these pipes can lead to water seeping into the foundation. Slab leaks can cause serious problems like structural damage, waterlogged floors, and even mold if left untreated.
Common Causes of Slab Leaks
- Pipe Corrosion
Over time, metal pipes can corrode due to reactions with soil and water. This corrosion weakens pipes, making leaks more likely, especially in older homes. - Abrasion
Pipes under your foundation can rub against the concrete slab, especially as they expand and contract with temperature changes. This friction wears pipes down, leading to leaks. - Poor Installation
Incorrect installation or low-quality materials make pipes more prone to leaking over time, especially if they weren’t insulated properly during construction. - Shifting Soil
Soil movement due to natural changes or cycles of rain and drought can put intense pressure on pipes, causing cracks or breaks. - High Water Pressure
High water pressure strains pipes, making leaks more likely, especially at joints or weak points.
Solutions for Slab Leaks
If you suspect a slab leak, there are several repair methods depending on the severity and location of the leak.
1. Pipe Rerouting or Re-piping
Rerouting involves installing new pipes to bypass the damaged section, avoiding the need to break through the concrete.
- Pros – Minimal disruption and quicker completion.
- Cons – Pipes may need to be run through walls or ceilings to prevent future issues.
2. Tunneling Beneath the Slab
Tunneling allows access to the leak without disrupting the interior of your home by digging under the foundation.
- Pros – Keeps your floors intact, less invasive.
- Cons – Requires skilled professionals to avoid structural impact.
3. Breaking Through the Slab
For leaks directly under the slab, breaking the concrete provides direct access for repairs.
- Pros – Direct access to the leak.
- Cons – Can be disruptive, with added costs for flooring repairs.
4. Trenchless Pipe Repair
Pipe Lining or Pipe Bursting involves minimal digging by inserting new pipes or liners.
- Pros – Little disruption and quick repairs.
- Cons – Requires specialized equipment and isn’t suitable for all leaks.
