Covering the EcoBloc Inspect system

Before covering the installation, all inlets, vents
and shafts must be connected. Ensure that the
geo textile 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 the trench is being backfilled, the installation
conditions described in Chapter 6.3 must be
observed and adhered to. Provided that the
installation situation does not require special
backfilling materials, the packed drainage system
is backfilled with coarse-grained, compressible
loose ground (gravel, crushed stone, sand etc.) at
least up to the top edge of the drainage system.
Above the top edge of the drainage system, any
excavated earth or similar can then be used for
backfilling the trench if necessary. Sharp objects,
larger stones or similar foreign objects should be
removed.
