DELIVERY AND INSTALLATION DETAILS:
Excavation length and width should be at
450-600mm (18"-24") larger than the
dimensions of the concrete tank. More
clearance may be required if work is to be
completed on the outside of the tank.
Excavated material piles should be located
at a distance away from the excavation in
order to allow access for the delivery
A bedding is required in order to minimize
stress on the tank structure. A bedding
should consist of 150mm (6" to 8") of clean
20mm or less (3/4" or smaller) crushed stone
or sand. The crushed stone must be level
with all large stones removed. The soil
conditions need to be stable enough to
support the weight of the tank and its
contents when full.
Delivery is made with a crane equiped truck.
Tanks can be placed in position if the site
is accessible. Firm flat ground is required
as well as 18 ft of overhead clearance.
NOTE: Crane operators can refuse to attempt
an installation that is not safe or that
could damage equipment and/or property.
CONCRETE/MASTIC JOINT SEALS:
The mastic sealant is to be placed on the
lower joint surface once the lower portion
of the tank has been placed into the
excavation. All joint surfaces must be clean
and dry before placing the mastic sealant.
Once the upper portion of the tank has been
set in place it will take some time before
the sealant has settled in the joint. The
time required will vary depending on the
temperature. Usually 12 - 24 hours. Avoid
backfilling before the tank has settled in
When backfilling the excavation care must be
taken to ensure that no stones or rocks are
placed against the tank. The machinery used
to backfill must not place its weight over
the edges of the excavation or on the tank
Tanks can float if the fluid level in the
excavation rises too high. Excavated
material can be placed on the top of the
tank in order to weigh it down. NOTE:
Filling the tank with water is not
recommended unless the outer walls are being
supported with fill. The water can place too
much stress on an unsupported wall.
