Vulkatec Riebensahm Gmbh

What Vulkatec Riebensahm Gmbh does

Vulkatec Riebensahm GmbH is a German specialty manufacturer of volcanic plant substrates, founded circa 1988 and headquartered in Kretz bei Andernach within the Vulkaneifel region. The company develops and produces substrates derived from natural volcanic raw materials — lava, pumice (Bims), and basalt — formulated for professional landscaping (GaLaBau), civil engineering, urban tree planting, green roof and facade greening, sports turf, container planting, indoor planting, agricultural use (Vulkafarm), pond filtration, and construction applications. Vulkatec self-describes as the market leader ("Marktführer") in the manufacture and development of volcanic plant substrates in Germany and serves both B2B commercial customers via direct sales and quote-based consulting, and private (B2C) customers through an online shop (Privatkundenshop).

The product portfolio comprises eight application-specific substrate lines plus two proprietary technology platforms: the Turbolift pneumatic delivery system, developed in the mid-1990s to blow substrates onto rooftops and hard-to-access construction sites via the company's own silo fleet, and the VulkaSense FDR-sensor-based intelligent irrigation monitoring system with NB-IoT connectivity and an app interface, launched in 2024. All products are engineered to comply with FLL roof greening guidelines, ZTV VegtraMü, DIN 18035, and DIN 18916 standards, with quality assurance anchored by RAL Gütesicherung and BRL 9341 certifications that require a six-month recognition process, internal and external third-party sampling, and annual renewal.

Distribution is handled entirely through Vulkatec's proprietary logistics fleet, which delivers substrates in bulk, Big Bag, bagged goods, or silo formats with just-in-time capability. The company sells across at least ten European countries — Germany, Netherlands, Austria, Switzerland, France, Luxembourg, Romania, Czech Republic, United Kingdom, and Poland — supported by a multilingual website (German, English, French, Dutch, Polish, Romanian, Czech), dedicated regional directors, and the Vulkatec Akademie (Baumseminare) education channel. The privately held GmbH is led by Managing Director Dr. Nicolai von Roenne.
