I'm planning to install the 8mm rubber floor over a tiled floor. Will this product work? If not, what are the other products you have that can work on top of tile?

Yes, you can install our Eco-Lock Rubber Tiles over an existing tiled floor. Our Eco-Lock Rubber Tiles can be installed over any hard flat surface like concrete, plywood, OSB, or any hard flat existing floor, like tile, laminate, engineered wood, luxury vinyl, commercial carpet, etc. If installing over a high pile carpet with a plush pad, we recommend placing a 1/4" plywood board over the carpet to prevent the tiles from separating when walked over.
