Consisting of interlocking 1-foot by 1-foot tiles, the Dri-Dek Self-Draining Floor System actually controls mold/mildew/bacteria while keeping people up off wet floors as the water drains away. The tiles are made of oxy-B1 vinyl, which inhibits a microorganism's ability to absorb oxygen, thus killing them. Cleaned by simply hosing down, the product is available in 12 colors and may be purchased as individual tiles, 3- by 4-foot sheets, or 3- by 12-foot rolls.
