THE HYDROPHOBIC HIGH-TECH AGGREGATE

The mineral lightweight aggregate ROTOCELL® becomes the high-tech waterrepellent granulate ROTOCELL PLUS® through a patented processing method. Due to this innovation a wide range of product
and processing advantages open up that increase energy efficiency and sustainability of products and applications significantly.


Natural expanded silicate was formed during the last volcanic eruption in Germany about 12,500 years ago.
Nature then produced an air-pore-rich, pebble-like mineral out of purely silicate raw materials was deposited just below the surface.
Since 1990, at its headquarters in Urmitz and Neuwied, Rhineland-Palatinate, ROTEC® has mined more than 180,000 tons of this ecologically excellent raw material per year and has been refining it into innovative
lightweight aggregates and ecologically valuable substrates.
NATURAL-EXPANDED SILICATE – A GIFT OF NATURE ROTEC® lightweight aggregates unite a world-class LCA:
