Slab leaks can cause extensive damage to your property if you don’t get them fixed quickly. They are a leading cause of foundation cracks, mold growth, and structural weakening. Calling a plumber is the best move for keeping your property safe and energy-efficient.
Quick Takeaways
- Slab leaks are usually the result of water leaking under the foundation of a home.
- These leaks frequently stem from pipe corrosion, soil movement, or poor installations.
- You’ll likely notice rising water bills, damp floors, and odors resembling mold or mildew.
- A plumber can use advanced tools to find the exact source and choose the best repair method.
- Getting timely help for slab leaks is paramount to preventing foundation damage.
What a Slab Leak Actually Is
Your home has a bunch of water and sewer lines running underneath its foundation. When these pipes develop cracks or pinhole leaks, the water or sewage leaks out into the surrounding soil.
Eventually, the trapped moisture erodes the slab foundation, cracking or shifting it out of place and leading to slab leaks.
What Causes a Slab Leak
There are many factors that increase the risk of slab leaks. Homes with corroded pipes, shifting soil, or high water pressure tend to be the most vulnerable.
Corroded or Aging Pipes
Homes with older plumbing materials usually experience more issues with corrosion and mineral buildup. Once pipes become weak, they often develop holes and cracks that let water leak out and cause damage.
Soil Shifting and Foundation Movement
When the foundation starts moving because of soil shifting, it’s much harder for the pipes to stay aligned. And when they become loose or stressed, slab leaks are more likely to occur.
Poor Installation or Low-Quality Materials
Properties with clay, cast iron, or galvanized pipes frequently present a higher risk of leaks and blockages. The buildup of sediment that occurs within the pipes makes it more difficult for water to flow smoothly.
As the pipes become weakened, the pressure may lead to slab leaks. Poor installation can be just as damaging, especially when joints aren’t sealed or supported correctly.
High Water Pressure or Temperature Changes
You might want your home to have high water pressure, but there is such a thing as too strong. Properties that keep the water pressure set above 80 psi are more prone to slab leaks.
The soil in Birmingham already expands and contracts frequently because of regular moisture changes and temperature swings.
Common Signs You Have a Slab Leak
Checking the property regularly for slab leaks is the best way to address problems in their earliest stages. If you notice any of the following red flags, give us a call right away. The sooner you take action, the better your chances of preventing costly foundation damage.
Rising Water Bills
Because slab leaks involve water or sewer lines leaking beneath the foundation, you’ll probably notice an increase in your water bills. You can compare recent statements to past ones to see whether there’s anything to worry about.
Warm or Wet Spots on Floors
If you notice warm or wet spots on the floor, this means the slab leak is pretty severe. The water has already penetrated the concrete and this problem needs immediate attention to prevent additional structural damage.
Mold, Mildew, or Musty Odors
Slab leaks usually produce musty and mildew smells because of the moisture buildup beneath the flooring. If you notice any of these odors, you should take fast action.
A simple surface cleaning or dehumidifier might be able to help temporarily. However, you’ll need a full inspection and professional repair to avoid long-term structural damage and mold growth.
Cracks in Floors or Walls
When slab leaks go unfixed for long enough, they’ll eventually cause cracks in your walls and floors. If you wait much longer to repair them, the foundation may completely shift or weaken.
Sound of Running Water When Everything Is Off
You should never hear running water under your home if you’re not using any faucets or appliances. If you do, call us right away. We’ll have to perform a leak detection test to see where the water is escaping.
How Professionals Detect a Slab Leak
We have a range of diagnostic options for finding slab leaks:
- Acoustic leak detection: We use sensitive listening devices to find the exact location of the leak.
- Infrared thermal imaging: We look for temperature variations to spot the source of the leak.
- Moisture mapping and pressure testing: We can measure changes in humidity and water pressure to pinpoint the origin of the leak.
Repair Options for a Slab Leak
We’ll take into account the pipe material, leak severity, and location to pick a repair option that provides the longest-lasting and most reliable outcome.
- Spot repair: Works best for small and isolated leaks when the rest of the pipe doesn’t show signs of damage.
- Pipe rerouting: The ideal option for fixing multiple leaks when the existing pipe has a long damaged section.
- Trenchless pipe lining: We don’t have to dig up the floor to make repairs. Using epoxy resin, we seal the pipe interior with minimal to no excavation.
