All services related to subsoil consulting and contaminated-site remediation, from a single source

KÜHN Geoconsulting® GmbH is an independent expert office  which has been active for more than 50 years in the areas of construction soil consulting and contaminated-site remediation. Having gained experience from over 22,500 contracts, ranging from detached homes to office skyscrapers, our staff provide professional, customer and practice-oriented solutions for all matters related to the projects.

Contaminated sites and demolition

In the field of contaminated sites, use our 48 years of experience in handling the discovery, investigation, assessment and remediation/securing of contaminated-site damage in soil, soil air and groundwater.

Our deconstruction services include the investigation and assessment of building materials which contain hazardous materials in the context of inventory and demolition field books as well as the design, organisation and execution of supervising restoration and remediation activities (including asbestos and PCB remediation).

Our holistic project management system includes all services and activities: from investigation and assessment, to planning, organisation and supervising execution. Thanks to our years of experience in all areas of contaminated site issues, we offer suppport in all projects by providing excellent consultancy, planning and execution.

Construction soil analyses and construction soil inspections

Our construction soil department provides you with all the key services in the context of construction soil investigation and foundation consulting: from pre-investigations and creating construction soil analyses, through to the supervision of construction activities and acceptance of foundation works.

Hydrogeological analyses

The teams in our hydrogeological department develop hydrogeological analyses as needed, and offer support concerning the planning and simulations related to all tasks concerning groundwater and surface water.

Geothermal energy

We develop feasibility studies, analyses and planning for facilities to use the earth’s heat in the areas of geothermal and regenerative energy.

Geographic information systems (GIS)

Our geographic information systems department develops interdisciplinary, transparent solutions for complex environmental circumstances using highly-specialised IT for geostatistics, geotechnical measurement systems and geographic information systems. Our application focus is on simulations, digital land and groundwater modelling, as well as geographic information systems (GIS).

Geographic information systems provide precise cost determinations and increase data transparency: a critical decision-making aide for official permitting procedures and the economical achievement of construction projects.

Measurement technology

In the context of many construction activities in the fields of building deconstruction, special civil engineering, well and sewer construction, increasingly highly sensitive measurement systems are used for geotechnical purposes (geological measurement technology) and for construction engineering (construction measurement technology).

Thus, even the smallest changes in the soil and buildings are monitored; critical changes and loads are recognised early; and negative effects are safely avoided.
