What Gesellschaft für technische Kunststoffe mbH does

Gesellschaft für technische Kunststoffe mbH (GftK), headquartered in Rheinbach-Flerzheim, Germany, is a privately held specialty manufacturer of paving joint mortars, bedding compounds, and surface coatings sold under the vdw brand. The company describes itself as a leading German manufacturer (führender Hersteller) of Fugenmörtel, with a portfolio of 19+ products spanning cement-based, epoxy 2K, and 1K polymer-modified mortar systems for pedestrian, light, medium, and heavy traffic loads, plus complementary bedding mortars, adhesion bridges, joint stabilizers, stone impregnations, and the COLOROUT traffic-surface coating line. Products are formulated for properties such as water permeability or impermeability, frost and de-icing salt resistance, weed inhibition, early trafficability, and color-stable aesthetic jointing, with technical data sheets available in seven languages.

GftK sells packaged dry mortars, two-component epoxy systems, and coating products primarily through specialist building material traders (Baustofffachhandel), with a particularly deep relationship through the hagebau purchasing group, which awarded the company the Industriechampion 2025 title at its GALABAU innovativ-Fachkongress. Distribution is supported by a field sales force covering all German postal code regions, a dedicated export sales manager, a wholly-owned international subsidiary (GftK-international GmbH) serving ~10 European countries, the GftK-Markencenter e-commerce portal, and a free technical hotline plus WhatsApp support. End customers include garden and landscaping companies, general construction firms, municipalities, and DIY homeowners.

The company holds ISO 9001:2015 certification, maintains a substantial library of tender-ready specification texts (Ausschreibungstexte) compliant with DIN 18318, ZTV-Wegebau, and FGSV regulations, and runs a seasonal workshop program for dealer staff and experienced processors. GftK is led by two managing directors (Rainer Harzheim and Marc Brucherseifer) and is privately held with no disclosed external investment.
