What is Basement Waterproofing?

Basement waterproofing is a method where your hired professionals use different techniques to block unnecessary water seeping inside your basement. In exterior basement waterproofing, your skilled professionals will excavate the walls outside your foundation to preserve the structural integrity. Similarly, in interior sealants, sealants are applied to your basement's wall and floor.

This process helps you protect and seal your basement from further water damage. Waterproofing your basement solves your house's moisture problem, and you'll be able to live in a safe and secure house.

While waterproofing your cellar, the professionals will perform an inspection, either for free or at a cost. Then, they'll choose a suitable method and start their work according to your basement's requirements.


Causes of a Wet Basement

You can face a wet basement due to various reasons. To make things easier for you to understand, we've listed down some of the most common reasons that cause a wet basement:

1. Condensation:

Condensation is the reverse of vaporization. When there's condensation, the basement's gas phase turns into the liquid phase. As a result, you'll see water sports, puddles, or droplets on your basement wall or floor. When you see this sign, you should consider waterproofing your basement.


2. Humidity:

In the summer, when the cool air of your basement collides with external hot air, it causes humidity in your basement. Sometimes, a dehumidifier might help, but sometimes, it might not. However, when you fail to maintain your basement's humidity, it causes basement wetness.


3. Cracked Foundation:

When there are crevices and cracks in your foundation, water seeps into your basement, which leads to wet basements. Cracked foundations can result from various factors, such as expansive soils, plumbing leaks, tree roots, drainage, earthquakes, poor soil, and more.


4. Plumbing Leaks:

Your basement is usually a dark and hidden space. Due to this, you might forget to check and repair it from time to time. If you forget to check it, you sometimes deal with different plumbing issues. We'd suggest you check your basement's plumbing if you're facing wet basement issues.


5. Mold Growth:

The basement of your house is usually deprived of natural light. Due to this, you can maintain a good humidity level in your basement. Mold usually grows in damp places, so that you can face mold growth issues in your basement. When mold grows in your house, you'll face a degradation of indoor air quality. Eventually, it will make your basement weak and wet.


6. Poor Drainage:

Most basements are not well managed enough to face water drainage problems. As a result, they can't handle an overflow of excessive water, which leads to a wet basement.


Methods of Basement Waterproofing

Check out our top four basement waterproofing methods as follows:

1. Interior Waterproofing

If you're facing water issues in your basement due to condensation, that's when you should consider doing interior waterproofing in the basement. This method redirects water that will enter your building into the drainage system. The coatings will be done on your basement's floor and walls to prevent basement leakage.

Interior waterproofing is a perfect solution for you if you're looking for an affordable and effective method. So, you should consider hiring a professional who is familiar with what they're doing. If you do so, you'll be able to rely on the waterproofing for many years to come.


2. Exterior Waterproofing

Exterior waterproofing is one of the most reliable waterproofing methods for your basement. This method prevents water from entering your house, so you'll have no fear of damage inside the basement. In this method, your waterproofing service provider will fully excavate on the bottom and around your foundation to make it strong. This way, external water won't seep inside your house's foundation walls at any cost. Polymers are used to coat the exterior of your house, which cures all the water issues instantly.


3. Foundation Crack Injections

In this method, your house foundation wall cracks are repaired from the inside without extracting any soil. The professionals you hire inject different types of liquid, like epoxy or polyurethane, around the cracked part. This process hardens your foundation, which prevents water from seeping inside your house.

This method is usually used to cover up cracks that aren't too huge and can be repaired instantly. However, if you have seen large cracks around your foundation, we suggest you not use this method.


4. Drainage Systems

You get moisture in your basement when there's drainage. If you want to get rid of drainage in order to keep your basement area dry. The drainage system available out there will redirect water away from your house foundation. Different kinds of soil drain away in different ways, so before installing any drainage system in your house, you should consider checking your soil type.

After that, you can install a sump pump to collect water that exists around your foundation or basement. No matter which drainage system you want to install in your home, it's better to consult a professional before doing so.
