The Causes of Slab Leaks and How They’re Repaired

A slab leak can be a serious problem that occurs with plumbing systems in a structure with a concrete slab foundation. While they can be caused by a variety of factors, slab leaks are most commonly caused by aging pipes, shifting soil, and improper installation.

The longer a slab leak goes unnoticed, the more damage it can cause to a home or building, making it essential to address the issue as soon as possible. In this blog post, we'll cover the causes of slab leaks and the steps taken to repair them.

Aging Pipes

One of the most common reasons for slab leaks is aging pipes. Over time, pipes can erode and deteriorate, which can lead to leaks. This issue is more common in homes that are a couple of decades old and have copper or galvanized pipes. If your home is older and you suspect you have aging pipes, it's important to have them inspected by a plumber.

Shifting Soil

If your home is built on soil that is prone to movement, such as clay, then the soil can shift and put pressure on the pipes. This constant pressure can cause the pipes to break or crack, leading to slab leaks. The most common way to identify if you have soil movement is through visible cracks in walls, ceilings, or flooring and doors and windows that don't close properly. If you live in an area that is prone to soil movement, it's important to have your home inspected regularly to identify any potential issues early on.

High Water Pressure

High water pressure can lead to slab leaks. If the water pressure in your house is too high, it can put undue stress on the pipes and cause them to develop leaks. You can check the water pressure in your house using a pressure gauge. If you notice that the pressure is consistently high, it is important to install a pressure regulating valve to reduce the pressure and prevent future leaks.

Repair Process

The repair process for a slab leak typically involves locating the source of the leak, determining the best course of action for repair, and then performing the repair. The most common method for repair is breaking through the slab, fixing the damaged pipe, and then patching the slab.

Another method is called in-place repair, which involves accessing the plumbing system through alternate openings, such as crawl spaces or walls. The repair method used will depend on the location and severity of the leak, as well as the accessibility of the plumbing system.

Prevention

Preventing slab leaks starts with proper maintenance and inspection of your plumbing system. Regular inspections can help you catch potential issues early on, making it easier and less expensive to repair.

Additionally, if you live in an area with soil movement, consider installing a foundation stabilization system that can prevent future shifting. Finally, when it comes to DIY plumbing work, it's important to know your limits and always hire a licensed professional to perform any plumbing repairs or installations.

Hiring a Professional for Slab Leak Repairs

Enlisting the services of a professional plumber can prove invaluable when dealing with slab leaks. Professional plumbers can accurately locate the source of the leak, assess its severity, and determine the most appropriate method of repair, whether it involves breaking through the slab or using an in-place repair technique.

Remember, DIY efforts can often exacerbate the problem, leading to additional costs in the long run. Hiring a licensed professional ensures that the job is done correctly, safely, and in compliance with local regulations, providing you with peace of mind that your home's plumbing system is in capable hands.

A slab leak is not a problem that should be ignored, and addressing it as soon as possible is crucial.
