DRIcore Subfloor Tile System

Many basement floors require the installation of a subfloor to provide warmth by raising the basement floor up off of the cold concrete foundation. Installing a subfloor tends to be a fair amount of work, as a traditional subfloor system consists of, according to DRIcore:

2x4 sleepers, vapour barrier, 1"-2" rigid insulation, 5/8" plywood and a lot of fastening.

The DRIcore system looks to be a more elegant solution. DRIcore comes in 2'x2' tiles and utilizes a tongue and groove system for easy installation. Also, from their FAQ:

DRIcore subfloor panels are engineered specifically for cold, damp environments typically found in basements. DRIcore subfloor panels are manufactured with a high density polyethylene moisture barrier that raises the 5/8" random wafer board core a ¼" away from damp, cold concrete floors. Since the panels are raised off the surface, the concrete floor is allowed to breathe.

DRIcore claims to save some headroom as well:

The combined height [of a traditional subfloor] is between 2 ¼" and 5 ¼" compared to 7/8" for a DRIcore subfloor panel.
