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") base,
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 geotextile

Geotextile forms the protective layer for the
EcoBloc Inspect system and prevents dirt from
entering the system. Damage to the geotextile
should be avoided.
The geotextile is placed lengthwise on the
blinding. Ensure it overlaps sufficiently 300 mm
(11.81") 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 EcoBloc Inspect ground plates

The ground plates are placed on the geotextile.
Each joint between the ground plates is fixed with
Eco connecting elements.
7.4

Positioning the EcoBloc Inspect flex

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