6.2 Anchoring
6.2.1 Anchoring kit (models 2.8, 3.4 and 4.1) for Ecoflo
®
stand alone
When a single riser is installed on models 2.8, 3.4 and 4.1, the biofilter (stand alone) must be anchored with the
geotextile provided to this effect before the final backfilling such as to maximize the stability of the unit.
Spread out the geotextile as illustrated in the following figures and make sure it overextends by 20" (500 mm) on
each side. Next, use the 6 ties provided to solidify the installation at the pultrusions. Add backfill material on top of
the geotextile to keep it in place.
6.2.2 Anchoring of model 5.7 and 7.3 - Installation of the extension pipes and membranes
To ensure that the shell does not move in the soil, install the six (6) extension
pipes onto the ends of the pipes in the shell. On each side of the shell, place a
section of membrane over the three extension pipes. Adequately spread out
and level the backfill material under and above the membranes.
6.3 Initial backfill of the shell
Backfill around the shell up to 8" (200 mm) below
the invert of the feed pipe. To backfill around the
shell, begin with the two longest sides and end with
the extremities. Note that the backfill material must
be laid down rather than pushed (do not compact
the backfill material using the power shovel).
The backfill material must be sandy and free of
rocks or stones.
ATTENTION: Make sure that no backfill material enters the shell during the backfilling operation.
