Basement Subfloor

During the process of finishing a basement, the basement subfloor is something that is typically overlooked. It is a very important part of protecting your basement renovations from moisture damage. When you are installing basement flooring, it is not a good idea to put it down on concrete unless the material is made to do so. Without a basement subfloor installed, moisture can build up underneath and cause all kinds of problems such as mold and mildew and a musty smell.

Experts in basement finishing will handle this in a few different ways. Some of the solutions that are used work for limited time, some are permanent, and some need to be avoided. Make yourself aware of these solutions to avoid any problems.

Basement Subfloor Solutions

There are a couple different ways that contractors will install a basement subfloor. It is important to make sure you know how your basement is being handled in order to avoid any issues that can come with moisture build up. The basement subfloor solutions typically done include the following:

  • Basement Waterproofing Paint is typically the most popular choice to go with. However, it is only a temporary solution. It may be able to keep water from evaporating into your basement, but it does not keep water from getting to the concrete slab. Eventually, it will start to crack and peel off.
  • Insulation Foam Board may seem like a good choice to go with since it does act as a thermal and a vapor barrier, but if it is placed right on the concrete, moisture can build up underneath due to poor air circulation.

  • Wooden Basement Subfloors are the worst choice to go with. Even if they are treated, they will eventually soak up the moisture and rot, causing mold growth, musty smells, and a weakened floor.
  • Basement Subfloor Products that are developed specifically to work in basements are the best choice. They work with the flat concrete surface, still allow proper air circulation, and keep water from evaporating into the basement.

When you are planning to finish your basement, make sure you choose the basement subfloor material wisely. Explore the options you have available to you and find a contractor that you can trust. You do not want to deal with the problems that can come from a moist and rotting floor.
