Are your 1” Monster Tiles suitable for outdoor installation? Is it ok for water to travel through and under the tiles? Will the granite color fade?

You can install our 1" Monster Rubber Tiles outdoors. Since these tiles feature a solid skin on top, water won't penetrate through the tiles but would flow off the top of the tiles and to the crack at the junction between two tiles. This will allow the water to get under the tiles and to flow to a drain or get absorbed into the dirt below. Our Monster Rubber Tiles are not UV stable, so the colors will fade over time.
