Enabling possibilities: We’re the trusted partner for the construction industry, municipalities, and industrial companies, both nationally and internationally. Our expertise ensures success in even the most challenging projects related to groundwater management.
Water is essential, but on construction sites, it can pose significant challenges. That's where we step in. Through targeted lowering of groundwater levels and advanced dewatering systems, we keep construction sites dry, whether they are linear projects, tunnels or metro developments.

Our freshwater resources are under increasing pressure from climate change and pollutants such as pharmaceuticals, microplastics and pesticides. Natural contaminants such as iron are also a challenge in many regions. We specialise in reclaiming water and making it usable again.

Whether for water utilities, mineral water producers, or industrial applications, we secure water supplies through advanced well drilling. With more than 30 years of experience and 10,000 wells drilled, we excel in even the most complex geological conditions.

We bring decades of well drilling expertise to geothermal energy projects, delivering sustainable heating and cooling solutions. From shallow to medium depth systems, we help harness the earth's energy for buildings. We make an important contribution to the energy transition and bring sustainable energy into your building.

When construction occurs below the groundwater levels, it's often necessary to temporarily lower the water table by extracting groundwater. If this extracted water is discharged into surface water or sewers, it's permanently removed from the natural groundwater cycle. Using our advanced technology, we return the extracted water back to where it belongs.

You can only manage what you measure. For sustainable groundwater management, it's vital to monitor groundwater levels and the environmental impact of water extraction. That's why we collect, control and monitor all water-related data.

As a specialist in dewatering and groundwater management, we continuously develop innovative, practical and sustainable technologies that meet the growing demands of our time. Our aim is to improve processes, conserve resources and find new ways to use water more intelligently.
Whether in civil engineering, pipeline construction, tunnelling or rural areas, our solutions are developed wherever conventional methods reach their limits. These include Hölscher weir systems, which retain rainwater across the landscape, and hw-dsi, a patented method for the effective reinfiltration of groundwater in construction projects.
