Concrete Slab Leak Repair in Portland

What is a Concrete Slab Leak?

A slab leak is essentially a water leak under a concrete slab. 

For example, do you notice any water seemingly coming out from under your house? This could be a sign of a concrete slab leak.

It might sound like a small issue, but a slab leak can actually cause a lot of damage to your home or building.

Why is Concrete Slab Leak Repair Important?

A concrete slab leak should never be ignored. 

If left untreated, the leak can cause:

What Causes a Concrete Slab Leak?

There are various explanations for a concrete slab leak. Figuring out the origin of the leak could help determine how best to repair it.

Here are a few of the culprits that can cause concrete slab leaks.

Poor Construction

One of the more common causes of a concrete slab leak is low-quality or improperly installed pipes. 

If the pipes were bent or dented in any way when installed, this could cause the pipes to break down quicker from the constant, abrasive water flow over time.

Pressure from an Outside Source

If the soil under your foundation shifts, it could put pressure on your pipes if your house moves slightly.

Soil can shift naturally, or it could happen due to soil erosion or an earthquake. If one of these is the cause of the slab leak, you could be facing major damage and even flooding if it’s not taken care of.

Pipe Abrasion

While pipes are being used regularly, they can rub against concrete, nearby pipes, or other materials. This can cause friction that wears down the pipes over time.

If the friction wears down a pipe enough, it could spring a slab leak.

Pipes that regularly run hot water can be at an even greater risk of abrasion because they expand from the heat, causing them to rub against their surroundings in the soil.

Poor Water Quality

Water that is excessively alkaline or acidic can corrode the pipes, causing a slab leak. 

The pH level of water tells us how acidic or alkaline it is. On a scale from 0-14, water can be:

How to Fix a Slap Leak: Repair Options

The method used to fix the concrete slab leak depends on the location and severity of it. Here are a few repair options that your plumber might suggest:

Re-Piping

Re-piping involves abandoning the old pipes but leaving them in place. Your plumber will re-route new pipes either through the attic or around the outer edge of the concrete slab.

Is that more work? Possibly. But it’s less expensive than having to jackhammer the concrete.

Spot Repair

If there is one leak that’s relatively accessible, it might be reasonable to jackhammer through the concrete in the one spot to repair it.

However, this might be a bit costly for a homeowner. In this case, you might need to re-pipe to avoid future leaks and subsequent damage to the foundation.

Pipe Lining

If you’re looking for a less expensive option, you might be able to get away with lining the inside of the pipes with a non-toxic epoxy coating. 

But this usually only works with tiny holes in copper pipes or very minor leaks in sewer pipes.
