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) (0,31"/0,63") blinding,
around 80 mm (3,15") 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/11,8") 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 geo textile.
Each joint between the ground plates is fixed with
Eco connecting elements.
Attention:
The direction of the ground plate defines the
direction of the Inspection channel. There is an
indication at the top side of the base plate.
7.4

Positioning of EcoBloc Inspect 230

The EcoBloc Inspect 230 is placed on the ground
plate. The Eco connecting elements are also used
to secure each layer.
The EcoBloc Inspect 230 is preferably laid
lengthwise with the inspection channel (open side).
