Eucalyptus DeckTiles. Imagine having beautiful hardwood flooring wherever you want it...in your home, on a balcony, or covering that old concrete patio. Now you can do it yourself, with these pre-assembled, pre-finished decktiles. These oil-finished eucalyptus deck "tiles" fasten together to create a brand new deck-like surface that can be permanent or there just long enough for a party. Since the decktiles are made from durable eucalyptus, your new flooring will be resistant to weather, moisture, and mildew.
