Installation

The size of the excavation depends on the dimensions of the EcoBloc Inspect system, leaving a working
space of around one metre all the way round, see chapter 5.3.
7.1 Construction & installation of an infiltration tank
The excavation bed must always be prepared as a
horizontal, level pit with load-bearing capacity.
Sharp objects, larger stones or similar foreign
objects should be removed.
A gravel (grit 8mm/16mm) blinding, around 80 mm
thick, is then applied. This is then drawn out flat
and serves as a base for the next stages.
7.2

Covering with geo textile

Geo textile forms the protective layer for the
EcoBloc Inspect system and prevents dirt from
entering the system. Damage to the geo textile
should be avoided.
The geo textile is placed lengthwise on the
blinding. Ensure it overlaps sufficiently (300 mm)
at the joints.
Since the entire EcoBloc Inspect system will be
wrapped with the geo textile later on, sufficient
coverage should be ensured at this stage!
7.3

Positioning of ground plates

The ground plates are placed on the geotextile and
connected with the Eco connection elements.
The EcoBloc Inspect 420 is preferably laid with the
inspection channel (open side) lying lengthways.
