What Causes a Slab Leak and How To Fix It
Slab leaks are nothing to fool around with. They can extensively damage your property and lead to structural issues that compromise the building’s integrity. Knowing how to identify them and when to call a local plumbing service is half the battle.
The other half is understanding how to fix a slab leak. At Iron Mountain Plumbing, our professional plumbers in St. George, Utah, specialize in that part. However, we can only help out if you contact us. So, our team outlined slab leak warning signs and our repair process below.
What Causes a Slab Leak in St. George, Utah?
Your plumbing network includes more than what you see beneath your sinks. It runs deep beneath the ground with a decent portion of piping beneath your home’s foundation slab. Sometimes, that portion springs a leak that spreads to other areas.
This water seepage is called a slab leak. Slab leaks develop for numerous reasons, including:
- Pipe corrosion: When pipes contact acidic soil or liquids, they might degrade much faster than they otherwise would. They can also become leaky and unstable from old age.
- Ground pressure: You might not notice it, but the soil constantly shifts. These movements push your pipes back and forth, which can eventually make them fracture.
- Old plumbing materials: All good things must come to an end, including even the most durable plumbing materials. Pipe lifespans vary depending on the material. For instance, metal pipes last longer than PVC or PEX.
- Poorly built foundation or plumbing: If the builders or plumbers responsible for the slab and plumbing didn’t use care, they might have jeopardized your home’s foundation. Laying a foundation is precise work.
- Chemical reactions: Some soils contain metals and other particles that react to pipe materials. These reactions might weaken the pipes and cause the slab plumbing to corrode faster than usual.
You aren’t likely to know the precise reason or how to fix a slab leak without a professional diagnosis. Slab leaks can sneak up on you, causing considerable damage because of their insidiousness.
Why Are Slab Leaks So Destructive?
Since slab leaks develop beneath buildings, they gradually destroy structures from the ground up. You can replace your roof or mend exterior and interior walls without the repairs having much influence over other parts of your home. However, underground issues directly beneath your home have far-reaching consequences for the entire building’s stability.
The damaging symptoms go beyond discolored water and low water pressure. You’ll find some of the more destructive slab leak signs detailed below.
Damaged Building Materials
Noticeable damage to your home is among the more prominent symptoms of a slab leak. The changes gradually occur and might slip past your radar for months. However, you’ll eventually face unignorable flaws, such as:
- Cracked walls: Small fractures or gaping cracks may form along interior or exterior walls.
- Warped flooring: If you don’t have a basement or crawlspace, your lowermost story likely rests on your foundation. You might notice grout and tiles or hardwood floors buckling upward from the shifting pressure beneath.
- Stained structures: As moisture seeps into your home, you might discover visible water damage, such as stains on light-colored walls, carpets, and other surfaces.
- Standing water: You might venture into your basement or lowest house floor to discover a puddle of water. Meanwhile, you don’t remember spilling any water there.
- Disturbed paint or wallpaper: The paint or wallpaper near the base of the walls might peel or bubble as moisture collects beneath it.
Mold Growth
The presence of excessive moisture or humidity makes for a hospitable environment for mildew and mold. You might not notice these sneaky fungal invasions at first. Mold colonies thrive on hidden surfaces beneath carpets, under wallpaper, and within closed-off rooms.
Most species live in undisturbed areas with restricted airflow, minimal sunlight, and plenty of humidity. However, as they proliferate, they spread to new spaces. You might notice dark green, brown, or black mottles developing on the structures closest to the leak.
Wasted and Low-Quality Water
Slab leaks often mean excessively expensive water bills. No matter how much caution you exercise, your water meter keeps running. Plus, you might hear trickling or rushing noises despite not running any fixtures.
Your water quality may also deteriorate under some circumstances. If the leak develops in a supply line, it could provide an entryway for common plumbing pathogens. A water quality test can detect these contaminants and possibly determine their origins.
Foundational Shifts
One of the most pressing reasons for finding out how to fix a slab leak is pervasive foundation cracks. These fissures develop as your home’s foundation literally moves around because of the water beneath it. The water erodes the dirt under the foundational slab.
The slab may rise in some areas, pushing chunks above the larger slab. Alternatively, it may sink as the soil washes away. You might notice these cracks in garage or basement cement or as consistent separations between the baseboards and floors.
How To Fix a Slab Leak
You can’t mend these types of destructive leaks by yourself, but a qualified plumber in St. George, Utah, knows how to fix a slab leak for you. These plumbing repairs go beyond basic pipe fixes or fixture installments, and they can sometimes be dangerous.
Detect the Leak’s Location
Every slab leak repair begins with slab leak detection. Your plumber needs to know the precise location of the leak before they can fix it. Otherwise, you could end up with a destroyed bottom story and nothing to show for it.
Many plumbers use waterproof cameras with infrared technology to detect leaks. Others might employ audio equipment that provides information about the leak size.
Prepare the Workspace
Since slab leak repair involves ripping up chunks of floor and foundation, you should move any furniture or belongings to a different room for the time being. Leave a clear, open space for your plumber to work.
Your plumber might also prepare the workspace by installing tarp coverings around the area to prevent concrete dust from infiltrating other parts of your home. Breathing in concrete dust is terrible for respiratory health.
Gather the Necessary Equipment
Next, your plumber will check to ensure they have the equipment required to complete the job. First, they will tick off personal protection equipment. After all, slab leak fixes are heavy, dangerous jobs that often require:
- Gloves for handling concrete
- Face masks and goggles to protect the eyes, nose, and mouth
- Thick clothing that covers all exposed body parts
- Steel-toed boots to protect the feet in case the plumber drops a heavy tool or piece of concrete
Your plumber will also need a jackhammer to break up the concrete slab and access the plumbing beneath it. Under some circumstances, they may need a machine that can lift heavy pieces of concrete. Once they pull away the concrete, they can perform the repairs to set your plumbing system back on track.
Choose the Best Repair Method
Plumbers use various repair techniques when approaching slab leaks. Some common methods include:
- Spot fixes: Some leaks are fairly small and contained. These may not require the more invasive procedures. Your plumber can quickly access and repair or replace a damaged pipe section without ripping up an extensive slab area.
- Pipelining: Another option for small areas of damage involves inserting a small amount of non-toxic resin into the pipe’s interior. The resin will cover tiny leak points. Once it hardens, it contains the water within the affected pipe.
- Repiping: Your plumber might repipe your slab plumbing if the pipe materials include galvanized steel, copper, and other metals. Repiping involves removing the damaged pipe section and replacing it with a brand-new pipe length.
- Rerouting: Your plumber might avoid jackhammering altogether by rerouting the pipes instead. This involves disconnecting attached, intact pipes from the damaged piece and reconnecting them with new materials.
Not all slab leak repairs involve jackhammering through the slab. Most plumbers reserve that aggressive approach for more extensive damage. Your plumber might access and mend the damaged pipes without altering your foundation if you are fortunate.
What If You Ignore the Slab Leak?
Unmitigated slab leaks are a recipe for disaster. If you don’t promptly repair the leak, you may struggle with:
- Health consequences: Mold growth and perpetual dampness will inevitably wreak havoc on your respiratory system. Some symptoms are mild and manageable while others result in lifelong conditions.
- Extensive water damage: Water damage costs big bucks to fix. You must replace or fortify saturated structures and materials to prevent future mold and ensure structural integrity.
- Devalued property: If you plan to sell a home with a slab leak, you will likely attract low-quality buyers with cut-rate budgets.
- Dangerous building structures: Sometimes, the foundation can collapse, which might even cause the building to collapse. At best, the building leans precariously.
