For more than 60 years, we at Hölscher Wasserbau have been providing targeted lowering of the groundwater level and dewatering systems for dry feet on construction sites. With individual techniques and processes we protect your project from groundwater or rainwater.
Whether private or industrial construction projects, we use the appropriate dewatering methods for every construction project. Our successful projects range from rainwater reservoirs and underground car parks, pipelines and cableways to highly complex construction pits for wind farms, shopping malls, underground stations or subway projects at a depth of more than 40 metres.
With up to 2,000 wells installed and more than 100 km of drainage per year, we are one of Europe’s leading experts in water management.
We work closely with our customers and find the best solution on the preferred dewatering method for your project taking into account:
Just a few reasons why our clients choose Hölscher Wasserbau:
Hölscher Wasserbau has a large selection of special systems and machines, such as the trench milling machine for groundwater lowering. Especially when constructing wind farms or power pylons on boggy ground, the custom-made design can be used more flexibly. The milling cutter also makes horizontal drainage possible in smaller pits.
With our branches, we are in service throughout Germany. Contact us and we will find your individual solution.
The technologies and processes we use, always depend on your project. Whether it’s cost-effective open drainage system with reinfiltration of water via ditches, seepage or drainage ditches into the floodplain or re-circulation in a closed system with wells and pipes, we always offer the right solution.
Every construction project is unique, so we use our many years of expertise to understand which solution best suits your needs. We are confident, we will always find the optimal solution, regardless of your challenges, to ensure that you complete your construction project on schedule and on budget
Our Services for your project
What happens to the water if it is removed from the aquifer? Hölscher Wasserbau makes every effort to keep the impact on the groundwater body as low as possible. Are you familiar with the patented and particularly sustainable hw-dsi® system?
Do you already know our individual solutions in the areas of groundwater treatment, remediation of contaminated sites and landfill technology? The responsible use of water is of great importance to us. That’s why we use modern methods to ensure that the water removed is free of impurities before it reaches the aquifer.
When lowering groundwater levels on construction sites, the effects on groundwater levels and aquifers must be investigated. Good groundwater monitoring continuously collects and analyses the most important data describing the nature and changes of groundwater. Remote monitoring is carried out with state-of-the-art PLC control technology.
