The company claims natural stone is more aesthetically pleasing to consumers: "There is no artificial building material than can rival the characteristic form and natural diversity of colours contained in natural stone."
Less energy is used to extract natural stone than is required to produce matierials such as concrete, Traco claims: "Nothing is lost during the production and processing of natural stone - it is quite simply a fully recyclable building material."
Traco’s Ulrich Klösser said: "Boulders, megaliths and rocky areas show natural stone in its most primordial form. Many different impressions can be made from boulders of different sizes, appearances and textures.
"This is particularly true of Japanese garden traditions, which have perfected the artistic handling of stones. Through these traditions, even the smallest landscapes can be shaped into places of quiet and well-being."
Commenting on the sandstone supplied by the company, Klösser said: "For many centuries, these stones in particular have been favoured in exclusive country houses, castles and churches, due to the fact that they are elegantly low-key making them particularly appealing."
The company sources sandstone, travertine and shell limestone from quarries in Weimar, Gotha and Bad Langensalza.
