LEOSTEEN- Steinholz today
So called the old technology for manufacture of
floors "Steinholz", was almost forgotten.
During the restoration of an old 19-century villa city
of Leipzig,
came across this technology and its potential as a
modern building material.
For ten years, I finished in my company which is
based on the "Steinholz" technology
LEOSTEENbetoncire coatings and design products.
