Making a safe & sustainable world possible
Ginger HPC has been working for people and their environment since 1948: we are specialist planners and experts in soil and groundwater, mineral and drinking water, building ground and geotechnics, urban water management, waste management, flora and fauna, as well as approval procedures, geothermal energy, building demolition, site assessments, occupational safety, raw materials, road planning and construction supervision, and much more.
With sustainability always in mind, we develop solutions for land recycling, environment and safety as well as infrastructure as an engineering company. We work in an interdisciplinary, international manner and with engineering precision.
Thanks to many years of experience, we are able to provide you with competent support.
Challenges are becoming more complex and are often interrelated. To master them, our employees combine their individual services and expertise in interdisciplinary teams. Their cooperation within and across sites leads to pioneering achievements – as evidenced by specialist patents and numerous publications. In selecting our methods and measures, we focus on accuracy, experience and innovation. We scrutinize every new technology and compare it with our experience before applying it.
With this knowledge, we also help our partners adapt to changes in climate change and provide constructive support with our experience as a sustainability consultancy: heavy rainfall risk management protects against severe weather, while our knowledge of groundwater management and drinking water infrastructure helps regions experiencing extreme drought. With our experience from decades of remediating contaminated sites, we are also equipped to adequately address new pollutants in soils, buildings and groundwater. We support companies and municipalities in identifying, preventing and disposing of pollutants, thus setting important trends in sustainable construction.
With future-oriented processes, we take the issue of sustainability seriously.
Through our work, we protect nature, human health and safeguard the values of our partners. We innovatively accompany the development of a greener economy with our engineering knowledge. Our expertise in geology and groundwater management is crucial for planning and building mineral water developments and geothermal plants or repairing damaged facilities. We take the topic of energy transition seriously.
We think globally across
all sectors.
To keep our finger on the pulse, we also rely on a network of many specialized sites – in Germany, Italy, Austria, Poland and Spain. As part of the Ginger Group and a founding member of Inogen Alliance we also work on international projects.
