Raw Materials/Surcharges
Rotopor® refers to mineral raw materials and aggregates in specific particle sizes. Depending on the product, the materials are screened, sorted, or washed.
Under the Rotopor® brand, we offer screened pumice, washed pumice, lava, gravel, and other materials for a variety of applications. Depending on the material and particle size, they are suitable for use as a drainage layer, leveling fill, filter material, or for the production of substrate mixtures.
Substrate/Soil
Using natural pumice as a base, we develop ready-to-use substrates and potting soils for various applications in gardening and landscaping.
From green roofs to tree growing media and cactus growing media, we offer tailored product solutions with specific particle sizes and properties for each application.
Lightweight surcharges
Using specially tailored processing methods, we transform natural pumice into specified granules in various particle sizes up to 16 mm.
Our lightweight fillers—ROTOCELL®, ROTOCELL PLUS®, and ROTOBASE®—enable a wide range of applications depending on the product and particle size and can help develop customized formulations across various industries.
