What BlasyMader does

Blasy + Mader GmbH (operating as BlasyMader) is a privately held German engineering consultancy founded in 1988 and headquartered at Moosstraße 3, 82279 Eching am Ammersee, Bavaria. The firm is organized around six integrated specialist departments: Abwasser & Fremdwasser (wastewater and infiltration), Altlasten (contaminated sites), Baugrund (geotechnical engineering), Bausubstanz (building substance), Grundwasser (groundwater), and Monitoring – Umwelttechnik (environmental monitoring). It is staffed by an interdisciplinary team of approximately 30 specialists spanning geosciences, engineering geology, geophysics, civil engineering, environmental engineering, and surveying, supported by secretariat staff and led by Managing Directors Stephan Bourauel (Dipl. Geologe) and Sebastian Kroiß (M. Sc., TUM).

The firm's core technology stack is a regulated, field-deployed engineering platform rather than a software platform: a DAkkS-accredited in-house chemical laboratory (DIN EN ISO/IEC 17025:2018, DAP-PL-3095.00), proprietary calibrated measurement and sampling equipment (automated samplers, multisondes for temperature, conductivity, pH, oxygen, COD, BOD5, TOC, and radar/ultrasonic/magnetic-inductive flow meters) deployable within 48 hours, and continuous monitoring infrastructure with remote data transmission supporting 24/7 data availability. Service delivery spans site investigations, expert opinions (Sachverständigenleistungen), hazard assessments per §18 BBodSchG, groundwater monitoring wells and water-rights procedures up to 120m depth, long-term environmental monitoring, sewage network investigations, and certified building substance assessments for controlled demolition. Multiple accreditations — §18 BBodSchG expert status, AQS 01/136/18 wastewater, TÜV-certified QMS, §7 SprengG explosives permit, and OFD-H / BAM recognition — make its outputs legally usable in regulatory submissions.

Blasy + Mader generates revenue through project-based professional service fees rather than subscriptions or product sales. Customer acquisition is direct via the company website, phone (08143 44403-0), and email ([email protected]), with accreditations and 35+ years of regional reputation serving as the primary credibility signals. The firm serves municipalities and associations, the construction industry, industrial and commercial clients, and facility operators — but no individual customers are named and no pricing is disclosed. Geography is restricted to Southern Germany, with no subsidiaries, no external funding, no parent company, and no public-market exposure. Equipment rentals for automated samplers and probes represent an adjacent revenue stream around the firm's existing measurement asset base.
