What is a Slab Leak?

A slab leak is a leak that is developed in the copper water lines which run down the concrete foundation of your home. The broken pipes will allow water to seep into the ground as well as the home’s foundation. 

If the same leaks are above the ground, either in the wall or ceiling, it is known as pinhole leaks. These leaks are due to long-term corrosion of copper pipes. Leaks are very dangerous if undetected and thus create huge water damage or even cause your entire home’s foundation to collapse.

What signs should I look for?

There are a few common signs to identify the leaks, first of all, check your water bills, if there is a sudden spike then there are serious leaks. Also notice if there’s low water pressure, new cracks in your walls or baseboards, or standing water around the outside perimeter of your home.

What Causes a Slab Leak?

Pre-Damage & Poor Installation

If the pipes are not installed properly in the beginning, then it won’t allow the water to flow easily. The damage to the pipe will cause problems in the long run.

Abrasion

Pipes naturally expand and contract as water flows throughout them, but it will create a problem. If the pipes are exposed to concrete, gravel, or even other pipes, they could start to rub against them.

Corrosion

Pipes will be underground right, so it’s only natural for them to come into contact with soil. Due to soil buildup, the pipes may corrode over time, this is very common.

Movement of the earth.

Earthquakes can cause slab leaks. But even if your area is safe from earthquakes, soil erosion and underground waterways can shift things around putting pressure on your pipes.
