So, what causes a leak in the slab?

With winter arriving fast and hard, with the rain, many homeowners are finding home maintenance and repairs that are needed. Like where slab leak and mold are and creating a slab leak from rain. Rain isn’t the only cause of a slab leak, causes can from other things like a busted pipe in the foundation or believe it or not, a roof leak.

When the pipes are inside the home or under the home’s foundation leak, it will begin leaking at the foundation too. Usually, these leaks are insignificant and small to start, but the damage they can cause get to be expensive and inconvenient.

When a slab leak isn’t addressed, the water will saturate the ground under your home. Your floors will become uneven and your home will slowly sink. It is important to address a slab leak as soon as you notice it, find where it is coming from and have the repair by a professional. 

Poor Constructed, Low-Quality Pipes

Homes that were not constructed correctly, or cheap piping was used are the most common slab leak causes. Either of those can lead to water pipes getting bent, dented, or kinked during construction and installation.

Exterior Pressure

High water pressure from the main water source can cause a slab leak. Another type of exterior pressure is when the ground shifts, causing the house to move will put the pipes under pressure. Ground shifting is normal within a certain amount, and other things that can cause the ground to shift are:

Earthquakes, Eroding Soil, or Underground stream

A slab leak from an exterior pressure is usually a large-scale incident with the potential of causing a lot of damage. That damage will lead to the pipes flooding the house and the immediate area around it.

Poor Water Quality

The pH level in your water can be too high or too low in acidic, making it hard water or soft water. Either way, this can cause pipes to corrode and create a slab leak. Any sign of a slab leak should be addressed immediately to avoid expensive or irreversible water damage.

Abrasion

A slab leak can be caused by abrasion. This happens when the water pipes are rubbing against a surface when the water is on. It could be a concrete foundation, the gravel used when the piping was installed, or rubbing against other pipes. The rubbing creates constant friction that will gradually wear the pipe down and ultimately create a slab leak. The pipes for hot water pipes are more apt to have this happen than the cold-water pipes because they contract and expand with the hot water.

Aging and Time

The biggest offender to create a slab leak is age and time. A slab leak is more common among older homes where copper pipes or galvanized steel pipes were used. These types of pipes are more likely to corrode over time and the extended period of pressure and stress on these pipes will lead to a slab leak. Regular inspection and performing necessary maintenance can help catch these things before they become a problem slab leak.

 Are slab leaks common?

Is a slab leak expensive? Thankfully, a slab leak isn’t a common problem, but they aren’t that uncommon either, and they are a stressful headache and they can be expensive. Sometimes a slab leak can be a simple fix, and sometimes, a slab leak is intense because it can require tearing up the house’s concrete foundation to find the leak. That part is messy and time-consuming. There are indicators that you can watch to catch a slab leak before it gets too bad.

Ground shifting: The ground shifts naturally, moving with the earth’s cooling and heating, slowly shifting water pipes and eventually causing a leak.  Or like earthquakes and sinkholes are dramatic shifts that can cause a slab leak.

Corrosion: Copper and galvanized steel water pipes interact with the minerals in the soil. After a time buried in the ground, the minerals in the soil and in the water eat away at the pipes, causing corrosion, thus, a slab leak occurs.

Faulty, inadequate wrapping: When water pipes can rub against a concrete foundation, or each other as they contract and expand with the temperature. This friction will wear holes and a slab leak occurs. By wrapping them properly, it provides protection from breakage and holes, thus preventing a slab leak.

Can water seep up through concrete slab?

The immediate, simple answer to this question is yes. Concrete is a porous material after it has dried, becoming sponge-like.  It won’t soak up water as a soft sponge will, but it will soak that sponge as it slowly seeps from a slab leak.

What are the signs of a slab leak?

There are seven signs you may have a slab leak:

  • A sudden spike in the water bill.
  • Water pooling around the yard where there shouldn’t be.
  • Carpet feels damp, hardwood floors are warping.
  • The appearance or smell of mildew or mold.
  • Water pressure is weak.
  • The water heater runs constantly.
  • Hot spots in the floor.

How do I find a water leak under my slab?

The last century has seen many advances in plumbing, still, as a homeowner, you shouldn’t be surprised to experience a slab leak at some time. Unfortunately, those water supply lines can be where there are leaks, sometimes beneath the flooring, and not discovered for weeks, even months.

  • To minimize this happening, a regular crawl under your house can be helpful.  Start by turning off the plumbing fixtures through the house. This will enable you to determine any source of water leaks if you find water pooling under the flooring in the crawl space.
  • Next, look at the water meter and if the dials are moving, this indicates the water supply line is leaking. Even the dial isn’t moving, keep the fixtures off and recheck the dials in an hour. If there is a change in the dial, you have a slow leak.
  • Locate where plumbing fixtures and water supply line valves connect. You’ll find the connections for the shower and tub in an access panel. Check the water lines to the water heater too.
  • Look under bathroom and kitchen cabinets where the P-traps are located. These are common areas for water leaks and can usually be fixed simply by tightening the fittings.
  • Next, turn the water on in one of the sinks, then with a flashlight go to the crawlspace. If you see damp spots or water dripping, you’ve found your leak.

If none of the checks listed above find a slab leak, it is time to call a professional. Finding and repairing a slab leak is just as important as finding and repairing a roof leak. Both are important to maintaining a healthy, stable home. Call 817-281-5325 today for your slab leak repair in Fort Worth, TX from Slab Leak Solutions.
