Load classes

6.1

Installation for pedestrian loading

When installing for pedestrian loading, vehicles of any kind must be prevented from driving over the sur-
face through structural measures or cordoning off. The permissable installation depths and max. earth
coverings are stated in
Tabelle 1
6.2

Green spaces above the EcoBloc Inspect system

If a grass is planted above an infiltration system, the system should be covered with a water-impermeable
geotextile or a layer of clay roughly 100 mm thick, otherwise the grassed area may dry out more quickly
than other areas.
6.3

Installation for vehicle loading

The minimum and maximum earth coverings differ depending on the various loading classes: car, lorry
12, heavy-duty lorry 30, 40 and 60.
The min. and max. earth coverings for the various loading classes. Deviating installation situations should
System covering (reuse excavated material and/or gravel) with a maximum weight of unit volume of
20kN/m³.

The installation depth depends on the loading classes and the angle of friction of the material used to
cover the EcoBloc Inspect system.
