Basement Subfloor Tiles

List of Manufactured Interlocking Basement Subfloor Tiles

By

Rather than creating your own basement subfloor from scratch (plywood, plastic, etc.), these basement subfloor tiles are an all-in-one solution. Typically, they are a sandwich consisting of a moisture barrier at the bottom, an elevating surface in the middle (usually no more than 1"), and wood top, usually OSB board. Other subfloor panels eliminate the OSB top altogether and are composed entirely of polymers. This list is no indication of ranking or quality; it's just a list of what is out there.

DRICore Subfloor

DRICore was developed by a former home contractor who had frustrating experiences with the classic basement subflooring system of 2x4s and poly plastic vapor barriers.  DRICore is "a raised high density polyethylene moisture barrier base bonded to an engineered core designed to allow air to flow underneath the subfloor system keeping floors warm and dry." 

DRICore panels are 7/8" thick.  Each are 2'x2' and are a tongue-and-groove attachment system.  The top of DRICore is OSB.  The bottom is a cleated, raised design to allow for air- and water-flow.

BARRICADE™ is similar to DRICore in that it also has an OSB wood top and the outer dimensions are 2'x2'.  However, BARRICADE™ Subfloor Tiles are a bit thicker (at 1.25" vs. DRICore's 7/8").  The chief difference, though, is the bottom.  BARRICADE™ Subfloor Tiles have a grooved x-pattern, as opposed to DRICore's higher cleat design.

ThermalDry

Lots of homeowners would like to install ThermalDry by themselves.  Unfortunately, that cannot.  ThermalDry is a proprietary product of Basement Systems, Inc. and requires installation by one of their certified, franchised installers. 

ThermalDry is a sharp departure from other subfloor tile products.  For one, it has no organic material that can potentially rot away.  For another, ThermalDry interlocks via a snap-together design, rather than the tongue-and-groove system of the OSB-topped products.  At 1/2" thick, ThermalDry is one of the thinnest subfloor tile systems on the market--though this is due to the absence of the OSB top found on other products.

DELTA®-FL

Delta FL is more like a souped-up vapor barrier than an actual subfloor tile system.  It's a roll-out polymer that is 5/16" high with a dimpled pattern to promote airflow.  Because each roll is 5' by 65.5', installation is fast.  If your finish flooring is a hard surface, such as laminate, you can install directly on top of Delta FL.  If it will be carpeting, an intervening plywood layer is required.

SUPERSEAL

Another all-in-one, roll-out basement subfloor product like DELTA-FL, Superseal comes in rolls as wide as 6'7" and as long as long as 51'.  SUPERSEAL is a dimpled moisture barrier that is 1/8" high.
