Covering the EcoBloc Inspect system

Before filling the installation, all inlets, vents and
shafts must be connected. Before backfilling
ensure that the geotextile is not pulled apart.
Overlaps must remain in place when filling.
The EcoBloc Inspect system must not be
driven over directly with construction
machinery.
When backfilling the excavation pit, the installation
conditions described in Chapter 6.3 must always
be observed and followed.
If the installation situation does not require any
special backfill materials, the EcoBloc Inspect
installation is filled with non-cohesive,
compressible loose rock (gravel, crushed stone,
sand etc.) at least up to the top edge of the
EcoBloc Inspect system.
If applicable, the excavated soil or similar can be
used above the top edge to cover the EcoBloc
Inspect system. Sharp objects, larger stones or
similar foreign objects should be removed.
