Deep pre-filtered wells
In the case of particular soil conditions, excavation depths and operational needs of the construction site, we create pre-filtered wells of a diameter between 200 and 500 mm and at depths of up to -10 m.
The particle size and quantity of material for the pre-filter are chosen according to the stratigraphic section and particle size of the soil concerned.
The wells that are made can be used to drain the groundwater naturally by gravity or artificially by means of a vacuum.
