Outdoor porcelain tiles are strong and hard-wearing. This porcelain is a far superior product to natural stone. Hard wearing and low maintenance outdoor porcelain is super strong and stain resistance. The Porcelain is fired in a kiln at over 1200 degrees Celsius. It’s non-porous which means it doesn’t absorb water and so it resists cracking from the freeze and thaw process. Also being water resistant means it won’t get soaked and crumble.
