Your basement is an opportunity waiting to happen. For some, it means extra storage space for seldom used things so that their living spaces may remain tidy. For others, it can become a finished living space—it can become whatever they want it to be!

But whether you want to turn your basement into a high-tech entertainment room or a party room with a neon-lined bar counter, you’ll also want to consider what kind of flooring you’ll want.

Maybe you’ve considered carpeting but decided against having another living space where you may have to deal with spills and stains. Hardwood flooring is a reliable alternative for those who wish to avoid carpet maintenance. What’s more, there is a wide range of hardwood varieties to choose from.

But before you start ordering your hardwood flooring or begin any other construction work in your basement, you should make sure your basement is prepared.

Prepared Means Safe for You and Your Hardwood Flooring

You may be wondering what preparation has to do with your basement. While it’s made of strong and durable concrete, it is a common problem for basements to experience invasive moisture or even groundwater leaks. This happens especially when it rains.

As rainwater soaks into the soil and comes to rest against the outside of your foundation, that water-laden soil creates what’s known as hydrostatic pressure. 

With every rain, there’s a chance that pressure can cause groundwater to seep through the cold joints (the seams between the foundation wall and footing and also where the basement floor meets the wall) and into your basement. That repeated strain can also eventually create cracks in the basement floor and/or wall.

These cracks provide easier ways for water to invade your basement, potentially causing water damage to your belongings, furniture, and hardwood flooring, especially if it’s made of cheap hardwood. A wet basement can also lead to problem scenarios, such as mold, which can affect your own health. So, using a high-quality wood filler for floor cracks is recommended to resolve this matter. 

How Does Water Harm My Hardwood Flooring?

Water and moisture are necessary for life in our world. That also includes the tinier things that live mostly beneath our notice. When there’s a persistent moisture problem or lingering water in the basement, there’s a good chance that it will draw problems.

Some of those problems are especially damaging to that hardwood flooring that you want to use! Here are some of the most common wet basement problems that can directly affect your hardwood flooring


Common house molds can damage the surface of wooden structures as they grow and seek nutrients in the wood. While releasing more spores, they can also agitate allergies and cause illness to those with weakened immune systems.

Wood Rot

Wood rot, on the other hand, will do further direct damage to your hardwood flooring. When there is wood rot growing on your hardwood flooring, it will cause the timber to soften and take on a spongy or bouncy texture. The wet rot will continue to spread across your hardwood flooring so long as enough moisture is available.


In a wet basement situation, with plenty of moisture in the air, your hardwood flooring can be like a buffet to a termite colony. They will devour your hardwood flooring as they tunnel through the material to create their colony chambers and tunnel networks.

While many species of ants are capable of building colonies in almost any building material, certain species, such as carpenter ants, love to create colonies in wooden structures. 

If your basement has hardwood flooring and a moisture problem, it can become a welcoming environment for an ant colony to move in.

Protecting Your Hardwood Flooring (and the Rest of Your Basement!)

The best way to keep your hardwood flooring and the rest of your basement safe from water is to install a basement waterproofing system. 

More specifically, an interior basement waterproofing system can help keep that groundwater moving out and away from your home. This, in turn, works to reduce hydrostatic pressure—ultimately, this means fewer chances for moisture and groundwater to enter your basement.

An interior basement waterproofing system consists of at least these components…

Installation of drainage channels is required throughout the floor’s perimeter in your basement. In these channels, water is gathered and directed toward the sump pit. There, a sump pump works to push the water out of your home via the discharge pipe.

Depending on your basement’s unique situation, you might also need other components such as moisture vapor barriers and/or a dehumidifier.

Once your basement has been waterproofed, you can finally begin the process of having your hardwood flooring installed, your drywall and carpentry put in place, and anything else you may desire to make your finished basement plans come true.
