What makes a good quality concrete tile?
A good quality tile should have a smooth, dense finish. It should not be porous or granular. Good tiles should be both strong and light. You should be able to stand on one without breaking it. Look at the underside of the tile: a good tile is branded, it is coloured through, and it has strengthening ribs and flanges for easy installation. It has a lateral joint beading free of concrete debris for easy overlap with adjoining tiles.
