InformatiKOM Karlsruhe – HAURATON drainage protects high-tech campus

Hidden technology: powerful rainwater management integrated into the design

The aim of the HAURATON experts was to keep rainwater in the natural cycle and prevent it from entering the sewer system. To this end, four infiltration swales with a diameter of up to two metres were created and 240 DRAINFIX BLOC infiltration elements were installed, each capable of storing 75 cubic metres of rainwater. These infiltration elements ensure the infiltration and retention of large quantities of water and are also designed for high traffic loads. A geotextile covering permanently protects the system from the inflow of fine particles.

In collaboration with project partners bau+grün and Bauer Landschaftsarchitekten, various channel runs were planned to direct rainwater to surrounding green spaces. These serve as retention basins and infiltration swales. Transport and cleaning are provided by low-maintenance DRAINFIX CLEAN filter substrate channels, whose CARBOTEC filter substrate reliably binds pollutants such as heavy metals and fine particles (AFS63). This ensures that clean water enters the infiltration elements and ultimately the groundwater.

An additional benefit: the channels not only support drainage, but also form a barrier-free guidance system around the InformatiKOM with their colourful and tactile design.
