The requirements placed on car parks are as varied as the range of linear drainage systems is wide. While the focus of commercially used parking and manoeuvring areas is centred on functional characteristics such as robustness and cost-effectiveness, car park design also plays an important role in those used privately. The HYDROblock drainage solutions and the MAXI system meet the requirements for areas with a load class of up to F 900, while the TOP system with a load class of C 250 and a wide range of grating variants is ideally suited towards being used for car parks for passenger cars.
