Products & services
Vertikale Entwässerung
Vertical filter dewatering is a common method for temporarily lowering the groundwater level. The filter system is determined depending on the local soil structure and the required dewatering depth. Our systems: - Vacuum filters - Gravity filters - T&C filters - Pressure filters
Frequency-Controlled Drainage
One of our dewatering methods is frequency-controlled dewatering using level measurement. The pumps are connected to a fully automatic control unit, which regulates the dewatering based on the required water level reductions. Level measurement is performed by data loggers in various monitoring wells on the construction site. Benefits: - Flow rate reduction - Reduced environmental impact due to reduced range - Savings on fuel and/or electricity consumption
Groundwater Monitoring
An important part of dewatering is flow measurement and monitoring of groundwater levels and their effects on the surrounding environment. Our systems: - Groundwater level lowering - Data loggers - Flow measurement
Water Treatment
Groundwater can contain all kinds of natural and non-natural substances, which may make it necessary to treat the groundwater before it can be discharged or infiltrated into surface water, the sewer system, or the soil. Our treatment systems: - Iron removal systems - Straw filters - Oil/gasoline separators (OBAS) - Stripping towers - Activated carbon filters
Temporary Pumping Systems
Many projects require temporary pump deployment. Our rental fleet consists of a wide variety of pumps and accessories such as piping, controls, water meters, and frequency converters. We offer customized solutions for pump installations, from design, assembly, and dismantling to monitoring and periodic inspections and maintenance.
Return Drainage
In return pumping, extracted groundwater is returned wholly or partially to the soil. This form of pumping is used at locations where lowering the groundwater level could have adverse effects on nature, buildings, or soil contamination. By applying return pumping, the sphere of influence of the pumping can be significantly reduced.
Deep-well dewatering
Deepwell dewatering can be applied to lower the groundwater level in large and/or deep excavation pits. Deepwell dewatering is also used at locations with a large inflow of groundwater from coarse layers and strong water-draining aquifers. A deepwell consists of a drilled well in which a submersible pump is installed. Drilling techniques: - Suction drilling - Flush drilling - Auger drilling - Cased drilling - Pulley drilling - Air drilling Our systems: - Vacuum extraction well - Gravity extraction well - Pressure extraction well
Horizontal drainage
For the development of large construction sites and long cable and pipeline routes, the application of horizontal dewatering is a highly suitable method for carrying out work in dry conditions. Using our drainage machines, a drain is installed to a depth of up to 7.8 meters below ground level. To promote groundwater inflow in poorly permeable soils, the drainage trench is backfilled with drainage sand. Advantages: - Safe construction site due to minimal above-ground obstacles - Reduced extraction rate compared to conventional dewatering - Less impact on the surrounding area due to central extraction - Savings on fuel and/or electricity consumption Our systems: - Vacuum drainage - Gravity drainage
