Can I Fix My Leaking Basement Walls?

Although basement condensation from leaking basement walls can be frustrating, some people have come up with various methods of fixing them. These fixes vary in quality and lasting ability.

Concrete Patches

A concrete patch may seem like a very sensible situation. Typically, a concrete patch goes on top of the area that’s leaking. You dry off the area from the inside, apply a concrete patch, and wait for it to dry. In an ideal world, the concrete would dry before the water was able to make its way through and it would stem the flow of the water.

Of course, this is rarely what happens. Instead, because concrete cures extremely slowly in the grand scheme of things, water almost always pushes through before the concrete has completely cured. Even if the concrete cures before water has come all the way through, remember that this doesn’t fix the root problem, which means you’re likely to experience it again.


Because you can often use epoxy as a tool to stem leaks in things like plastic tubing and copper piping, many people then wonder whether they can mix epoxy to use on their leaking basement wall. That has led to a number of people who believe they can DIY their leaking basement wall fix. After all, epoxy is waterproof, right?

Although epoxy can be a very useful tool in some situations, it’s not as useful when you’re dealing with a leaking basement wall. Leaking basement walls are leaking for a reason; more often than not, that small crack will grow or be joined by a variety of other cracks, which you’re not going to be able to fix with epoxy. You need to fix the base problem before you move onto other fixes.

Basement Dehumidifier

Some people just install a basement dehumidifier. After all, if it pulls moisture from the air, it should be able to pull condensation from your wall as it appears. This concept stems from an idea that’s unfortunately common among homeowners: the idea that a dehumidifier is strong enough to remove water that’s already condensed onto a surface.

A dehumidifier may be able to help avoid excess moisture in the air because of a leaky basement wall, but it’s not going to remove the leaks in the first place. Remember, there’s a reason a leaky basement wall exists; it doesn’t just appear out of nowhere. If you can fix the source of the leaking, you’ll be much more ready to take on the problem of fixing the leaks themselves.

Professional Basement Waterproofing

Lastly is professional basement waterproofing. These other potential “fixes” are typically quick and easy, and some are very cheap, while others may not be quite as much. However, the problem is that these “quick and easy” fixes, while nice in the short term, are absolutely not worth it in the long run. When you cheat your basement out of a strong fix, you’re going to end up with issues that just compound in on themselves.

The only way to get a true fix for your leaking basement walls is to invest in professional basement waterproofing. This will take longer and likely be more expensive than just putting up a concrete patch. However, it’s up to you: Do you want a fix that’s cheaper and less difficult, or do you want a fix that actually works to stop the problem?
