What naue sealing does

Naue Sealing (legal entity: Naue GmbH & Co. KG) is a German privately held geosynthetics manufacturer and certified sealing installer founded in the 1970s and headquartered in Germany. The company designs, produces, and sells a broad portfolio of geosynthetic products organized into five core families: Secugrid/Combigrid geogrids for soil reinforcement, Bentofix geosynthetic clay liners (GCLs) and Carbofol geomembranes for sealing and containment, Secudrain drainage mats, Secutex geotextiles, and Secumat erosion control systems, including newer biodegradable Green variants and specialized products such as Secutex Soft Rock sand containers and Naue GlacierProtect. All product manufacturing is paired with a certified installation services business delivered by DVS-2212-qualified plastic welding specialists, and the company holds TÜV Nord WHG, AK GWS, and AK Tunnel/STUVA certifications that qualify it for regulated landfill, groundwater protection, and tunnel projects.

Naue generates revenue through four streams: (i) one-time sales of physical geosynthetic products, (ii) certified professional installation services on customer projects, (iii) engineering support and consulting, and (iv) subscription-style access to the NauePortal geotechnical software suite, which bundles over ten calculators (PavedRoad AASHTO, UnpavedRoad modified GH, AxleLoad, Platform design, VeneerReinforcement, SecuCalc, Erosion-Control, RetentionPond, Softrock, and SolutionFinder). The go-to-market is enterprise field sales: direct engagement via the Naue Customer Center, supported by a globally localized website in eight languages, case-study content, technical documentation, webinars, and a digital portal designed to drive product specification earlier in the design cycle.

The company serves nine primary use-case segments: tunnel construction, landfill engineering, civil engineering (roads, foundations, earth structures), and groundwater protection are flagged as primary; hydraulic engineering, mining, railway engineering, renewable energy, and erosion control are secondary. Customer concentration is not disclosed and no named end-customer logos appear in the source; the business is project-based with a long tail of infrastructure, mining, and environmental engineering buyers across Europe and globally. The company operates as an independent, family- or founder-controlled KG with no parent company, no disclosed institutional investors, no M&A history, and no leadership turnover visible in the source data.
