Height
According to
valid guidelines
Min. 400 mm
Min. 800 mm
Max. 2250 mm
To top edge
Blocks
800 – 100 mm
Please note:
The infiltration ditch modules are installed
and connected in accordance with section
5. Ventilation heads should be installed in
green spaces.
The backfill materials of the different soil
layers may have a maximum specific
weight of 20 kN/m³ [124.86 lbs/ft³].
The soil layers must be evenly distributed
all round and compacted in layers of max.
300 mm using light or medium compaction
equipment. A degree of compaction Dpr of
97% should be achieved.
The use of compaction equipment with vi-
bration switched on is not permitted.
Sudden backfilling with large earth masses
is not permitted.
Properties
Observe local conditions with regard to frost-
free installation depth
Macadam road base
Free from foreign objects
E 45 MN/m²

Infiltration application: completely wrapped in
geotextile to prevent dirt ingress from the
surrounding soil
Retention application: 3-ply layer structure
(geotextile-sealing sheet-geotextile) to pro-
tect the sealing sheet and make the tank wa-
tertight
Gravel 8/16 mm [0.31/0.63"]
free from foreign objects (e.g. roots, shatter,
waste or organic material)
The permeability of the side backfill should
at least correspond to that of the existing
soil.
