Can tiles, particularly rectified tiles, be laid seamlessly?

Within a ceramic covering, joints have to compensate for unavoidable material tolerances caused by the manufacturing process. Furthermore, these also dissipate tension from the substrate, particularly with heated floor structures. In addition to compensating for the above-mentioned tolerances, joints also have the advantage of preventing water and dirt from penetrating into the tile covering. A cement-based joint prevents the penetration of bacteria, mould, etc. The alkaline cement-based environment in the joint impedes the growth of such organisms. This is why we do not recommend laying tiles without grouting material in between.
