What Geoplan does

Geoplan GmbH is a German privately-held engineering consultancy founded in 1993 and headquartered in Neukirchen-Vluyn (Ruhr area), with a southern branch office in Seligenstadt near Frankfurt am Main. The firm specializes in the application, inspection, and testing of geosynthetics (Geokunststoffe) and related geotechnical and environmental engineering services. Its core work centers on independent third-party inspection (Fremdprüfung) of geosynthetic sealing systems used in landfill construction and tunnel waterproofing, conducted under DAkkS accreditation as an inspection body (DIN EN ISO/IEC 17020:2012, Type C) with BAM listing, and on physical/mechanical laboratory testing of polymer products such as sealing sheets, geotextiles, drainage elements, and plastic pipes in its DAkkS-accredited testing laboratory (DIN EN ISO/IEC 17025:2018). Beyond inspection and testing, the firm provides geotechnical consulting (Geotechnik), environmental and contaminated-site assessments, and a Sachverständigen-Organisation authorized under §52 AwSV by LAHUV NRW for inspecting facilities handling water-hazardous substances, including heating oil tanks (Heizöltank-Prüfung) and LAU/HBV plants.

Geoplan serves four primary use-case segments: landfill construction (Deponiebau), tunnel construction (Tunnelbau), groundwater protection / facility inspection (Grundwasserschutz / Anlagenprüfung), and geotechnical engineering (Geotechnik). Its customers are German municipal waste-management authorities (e.g., AVR Kommunal, Kreisverwaltung Bernkastel-Wittlich, ZAK Kaiserslautern) and industrial enterprises with legacy or active landfill sites (e.g., TERRAG, Neue Halberg Guss, Outokumpu Nirosta), alongside property owners and operators of water-hazardous-substance facilities. Service delivery is sales-led and project-based, executed via direct engagement through the headquarters and branch offices and a nationwide network of seven named certified Sachverständige spanning multiple German federal states.

The firm generates revenue through four documented streams — Fremdprüfung, Prüflabor, Anlagenprüfung, and Ingenieurleistungen — all classified as professional services. Pricing is quote-based and tailored to project scope and is not publicly disclosed. The company holds no external investors, has no subsidiaries or parent, and operates as a founder/management-owned GmbH under managing director Dipl.-Geol. Martin Schalkowski, with no funding rounds, M&A activity, or restructuring events on record.
