What You Need To Know About Slab Leaks

A slab leak is a leak in the plumbing under your home's foundation. When you discover that you have a slab leak, it is important to determine the cause and location to have it repaired right away. Continue reading to learn more about how a professional can find the leak and some of the causes of slab leaks.

Locate the Leak

Since the plumbing under your foundation is leaking, you may have nightmare inducing pictures in your head of your foundation being torn up to find and repair the leak. You can rest easy because, if you hire a professional, they will not break your slab in multiple places to find the leak.

Instead, they can locate the leak with specific tools and equipment such as electromagnetic pipeline locators and electronic amplification equipment. The professional can find the leak and minimize destruction of your property when fixing it. In some cases, only a floor tile will have to be removed.

Causes of Slab Leaks

  • Poor construction: Any construction that takes place has the potential to damage the plumbing under your foundation. Additionally, the original construction of your foundation and plumbing system could have been faulty upon installation, which will lead to leaks.
  • Abrasion and vibration: When water travels through pipes, the pipes can vibrate, expand, and contract. These movements can cause the pipes to rub against the surrounding materials, which are usually abrasive, like concrete or gravel. Eventually, this abrasion rubs a hole in the pipe and causes a leak.
  • Corrosion: The exterior of the pipe, the soil, and the water inside the pipe can work together and create a  charge that causes electrolysis in the pipes. The electrolysis causes the pipes to corrode and creates holes that lets the pipes leak.
  • Pressure: Pipes that are underground can be crushed or creased due to pressure. Pressure may come from uncontrollable forces such as earthquakes or from something completely preventable such as poor construction methods. Creased pipes will cause the pipes to wear down unevenly and leak. Crushed pipes will leak from multiple places, building up to a significant leak that will wash away the soil that is supporting the foundation.

If you have a slab leak, the good news is that, with the right professional, the damage to your property can be minimal in order to repair the leak in most situations. As you can see, some of the causes of slab leaks are easier to prevent than others. Be sure to hire skilled professionals to do slab leak repairs to prevent any problems.
