Customer
Responsibilities
- Expose both ends of
the casing, verify length and size of casing.
- Check for
unobstructed vent access to casing.
- Install a top vent
(2”) on the high end of the casing, and a bottom
vent (2”) on the low end of the casing. Vent height
must be at least 4” higher than the actual casing.
Suggested vent sizes: 2” up to 1,000 gallons, 3”
from 1,000 to 2,500 gallons, 4” over 2,500 gallons.
- Vent opening into
the casing should be 2” minimum.
- Trenton recommends
optimal vent placement to be at least 12” from end
of casing. Shorter distances are acceptable, as long
as the vent is not restricted by the end seals or
spacers.
- Remove seals and
inspect condition inside casing.
- Flush casing, if
necessary, to remove debris in casing.
- Seal both ends of
casing with end seals.
- Air test casing and
seals with 5 psi for approximately 15 minutes.
- If the casing passes
the air test, back fill and schedule fill.
- Communicating any
difficulties in preparation of the casing, access to
the job site, and time scheduling (safety meetings
or early quit times, etc.) will help expedite the
work, and will assist Trenton Corporation in
achieving the maximum fill percentage.
Trenton Fill
Procedures
- A company
representative must accompany Trenton personnel on
the job site at all times.
- Air is blown from
the top vent to the bottom vent at or below 5 psi to
remove any water that may be present and to ensure
adequate flow between vents.
- Pre-Con is poured
into the fill vent at a ratio of 1 gallon per 200
gallons of filler.
- Fill Coat # 1 is
pumped into the casing thru the bottom vent when
possible.
- The fill process is
normally completed when the filler is displaced from
the discharge vent.
- Any Fill Coat # 1
discharged from the vents will be cleaned up by the
Trenton crew.
- It is the customer’s
responsibility to remove excessive amounts of Fill
Coat # 1 that leak from the casing or end seals.
Trenton personnel will determine the acceptable
limits for cleanup.
- Any prolonged delays
by the customer after Trenton has arrived at the job
site may be subject to a “down time charge” of
$350/hr (10 hrs/day max.)
Important Note:
Casing or carrier temperatures that exceed 110°F or
higher will cause Fill Coat #1 to melt and expand. This
could cause material to be discharged from the vents or
any other openings in casing.
