The website's title ('Geotechnik und Tunnelbau') and footer content (mentioning services like 'Construction Supervision', 'Project Design', 'Structural Design', 'Geotechnics', 'Consulting', 'Inspections') clearly indicate a focus on the construction and engineering industry. The language is primarily German, as suggested by the title and the 'DE' suffix in the footer, with English used for standard business terms. The website serves as a corporate portal to present company information and services.
