Please note:
The infiltration ditch modules are in-
stalled and connected in accordance
with sections 6 and 7. Ventilation
heads should be installed in green
spaces.
The backfill materials of the different
soil layers may have a maximum spe-
cific weight of 20 kN/m³ [124.86
lbs/ft³].
The soil layers must be evenly distrib-
uted all round and compacted in layers
of max. 300 mm using light or medium
compaction equipment. A degree of
compaction Dpr of
achieved.
The use of compaction equipment
with vibration switched on is not per-
mitted.
Sudden backfilling with large earth
masses is not permitted.
