FlooringInc 40 Outdoor Basketball Court Tiles, 12"x12" Tiles, Camel's Back

[This review was collected as part of a promotion.] I purchased this because I have an outdoor stairwell going down to my basement door and the drain is always getting covered by leaves which results in water flooding my basement. Even if I clean out the well, all it takes is a few large leaves to block the dome drain cover and I flood. So I placed these tiles across the entire floor and this fall I have had no flooding issues. Even if a bunch of leaves come down during a storm, there is always a way for the water to go beneath the flooring and get to a drain, and after several large storms I have been flood free. While it is very permeable, the holes are also very small, much smaller than the holes in my old drain cover, so it actually prevents less garbage from going down and clogging my drain as well. The tiles are easy enough to cut with a jigsaw so that you can fit them exactly to the space needed. Although you should wear heavy leather gardening gloves to hold them while doing this as it isn't very comfortable to hold the tiles while cutting. It took me maybe an hour to measure, cut, and install the tiles over a 4' x 4' area. While they don't sit flat on the ground due to the floor being gradually sloped down to the drain in the middle, it doesn't present any problems for walking on it, it is flexible enough that your weight just pushes the flooring down to the ground as you step on it. I did order samples of several different types of tiles prior to ordering, and this tile was the most permeable and offered the most unobstructed path beneath the flooring for water to travel. I highly recommend this for anyone who has an outdoor stairwell that they need to clean regularly to prevent flooding.
