Basement Finishing - ThermalDry Insulated Floor Decking: Revolutionary Waterproof Basement Subflooring

ThermalDry Insulated Floor Decking is a revolutionary basement subflooring product from Basement Systems. The insulated decking is made from inorganic materials, designed to withstand damp conditions, flooding, and plumbing leaks, which are all common in basements.

In this video, Larry Janesky, founder and owner of Basement Systems explains why it’s a bad idea to install finished flooring on top of a cold, damp concrete slab. When water vapor passes through the porous concrete slab from the soil, water vapor and humidity can build up underneath wood subflooring, and mold and rot can quickly become an issue. Water from a plumbing leak can also damage the plywood decking. Without a solid, waterproof base underneath, finished flooring will be ruined and will need to be replaced.

ThermalDry Insulated Floor Decking is a smarter alternative to the built-up plywood subflooring that is traditionally used by contractors. The waterproof, insulated subflooring is made from inorganic materials that will never get moldy or rot. A 1-inch layer of SilverGlo foam insulation helps keep basement floors warm. A magnesium oxide board provides a durable base for your chosen finished flooring. A cross-hatch pattern of grooves on the bottom of the ThermalDry Decking panel allow moisture from a plumbing leak to eventually dry. With ThermalDry Floor Decking, your basement floor covering will be protected from any water vapor that travels through the porous concrete slab.

There are a number of floor covering options to install over the ThermalDry insulated subfloor. Basement Systems recommends installing vinyl wood-grain flooring, but wall-to-wall carpeting can also be installed.

Basement Systems dealers fix more than 53 thousand basements each year across North America. In addition to keeping your basement floors dry, your local Basement Systems contractor can also waterproof your basement with WaterGuard perimeter drainage, a TripleSafe sump pump, a SaniDry basement dehumidifier.

Once your basement floor is dry and insulated and your basement is waterproofed, you can build the finished basement of your dreams!
