Added value for people, buildings and cities

The air is clear

Hytect technology is permanently burned into the ceramic surface at high temperatures. When light falls on the coated tiles, active oxygen is released via photocatalysis. This provides the effect against bacteria and mould. At the same time, Hytect tiles neutralise pollutants in the air in an entirely natural manner. Because they are also hydrophilic, it is hard for dirt or grease to gain a foothold. Each of these effects continues to apply across the entire life cycle of the tiles. And thanks to an extensive range of products, Hytect ceramic can be used in a wide variety of areas.


Guests rightly expect maximum cleanliness in swimming pools. Hytect ceramic tiles help pool operators to achieve this goal in an environmentally-friendly manner. Dust, dirt or even residues of soap and cream are unable to gain a foothold on Hytect surfaces. Neither in swimming pools nor showers at sports facilities or gyms. As soon as Hytect surfaces come into contact with water, a fine film of water is formed on them. Dirt is simply infiltrated and easily wiped away – if it has not already been rinsed off while showering.


Hygiene measures are specified in hospitals, doctors’ surgeries and nursery schools. Hytect helps to comply with them. Active oxygen reliably destroys bacteria, viruses, germs and spores. This occurs invisibly on Hytect tiles as this effect can be neither seen nor smelled. Nevertheless, they provide long-term support in surface disinfection in hospitals etc.

The air is clear

Hytect neutralises pollutants such as NOx or formaldehyde over the entire life cycle and actively ensures a better indoor climate. This has a positive impact in modern buildings in particular which are practically air-tight thanks to insulation.

How Hytect works

Degradation of nitrogen oxides in inner cities

Due to the high nitrogen oxide emissions, driving bans are threatened in many German city centres, including Berlin, Hamburg and Stuttgart. However, several cities such as Bonn, Düsseldorf, Essen (here even a section of the A40 motorway) or Cologne are also affected in NRW, a city with a high population and traffic density. Building materials with photocatalytic surfaces in public spaces can help to significantly improve air quality. With the Hytect technology AGROB BUCHTAL has almost 20 years of experience in the manufacture of ceramic coverings with photocatalytic surfaces.
