These "concrete punkers," the engineer Jiří Peters and the marketer Ladislav Eberl, claim that they were able to give a soul to the concrete. The desire to do business and excel in something new brought fame to these young Czech men thanks to their brilliantly ordinary idea.
Their company designs concrete products from seats to interior or jewelry accessories (together with Tomas Vacek, a designer and third member of Gravelli team). They won an award for the best Czech innovation of 2013 for the unique building material, composed of high quality concrete and transparent elements. This also holds the world patent.
In 2015, in Forbes magazine they were announced among the 30 under 30 in the Czech Republic, and were nominated for Czech Grand Design or the "Idea of the Year 2013" award.
