Perform the same work as in dry ground conditions with the additional recommendations and
modifications below:
For installations in a high water table area, ensure the adequate drainage of the excavation during
installation.
Anchor the unit(s) to the concrete slab (slab thickness should be a minimum 150 mm)
The base must extend to a minimum distance of 300 mm beyond the base of the tanks on all sides
If you are unsure, a qualified civil engineer should be consulted
Anchoring the tanks to the base is achieved with a system using the anchoring points; these
are positioned on the lower corners of the tanks
For installations in a high water table area, ensure the adequate drainage of the
excavation during installation and anchor the unit to the concrete slab
Important:
The tanks should be secured and anchored to the concrete base
In all high ground water conditions, the backfilling should be carried out to a level of 20 cm below
the tank covers.
We recommend that the tanks are backfilled with (lean mix) concrete instead of a regular backfill
